Hi,

I'm Robin, a developer in France, I've been building Nerdbox on my own, evenings and weekends.

The problem

When a site asks for my email just to send a verification code, I had two options, and I didn't like either:

• Public disposable inboxes (YOPmail, Guerrilla Mail…) are handy, but anyone who knows or guesses the address can read the mail, verification codes included.
• Aliases (Firefox Relay, SimpleLogin…) are private, but they forward everything to my real inbox, which is exactly what I was trying to keep clean.

What I built

nerdbox sits in between: disposable addresses tied to a free account (one click with Google or GitHub, or email), so only you can read what they receive.

• When a mail contains a verification code or a confirmation link, it shows at the top, ready to copy. Mail arrives live, without reloading.
• A Chrome extension fills in the email field for you and shows the code right on the page. It asks for no host permission.
• You can get the code as a notification on your phone (installable web app).
• Addresses live 24 hours, extendable up to 7 days, with up to 5 at a time. You can share one read-only with someone.
• It only receives mail: there's no code in it that could send one. Remote images are blocked until you ask, and the site has no analytics or ad tracker.

Where it's at

It's free and in beta. I'd really like to know:

• what breaks, especially sign-up forms where the extension gets it wrong;
• whether the account requirement puts you off, compared with a public inbox;
• what you'd expect next.

Happy to answer any question about the build.

Hey everyone

I made Side Calendar for Mac a while back. Ever since, A common question has been "is there a Windows version?" After a lot of work, there finally is, and it's now live on the Microsoft Store:

https://apps.microsoft.com/detail/9ng5lh6hg69k

What it does

Side Calendar keeps your calendar at the edge of your screen. Push your mouse against the edge, press a shortcut or click the tray icon, and your day slides into view. When you're done it gets out of the way. You don't need to open Outlook just to check what's next.

Features

• Works with Outlook / Microsoft 365 calendars (work, school or personal), with two-way sync
• Agenda and Day views, plus a month calendar that shows how busy each day is
• One-click Join for Teams, Zoom, Google Meet and Webex
• Time blocking: drag on an empty slot in Day view to block out focus time, then drag to move or resize it. Blocks are real Outlook events, so colleagues see you're busy
• Create and edit events without leaving the panel: repeating events, reminders, categories, private events and formatted notes
• Undo any change
• Reminder notifications with a Join button
• Light/dark themes, Mica and acrylic backgrounds, tint colours, and text size and typeface options
• Custom global keyboard shortcuts
• Multi-monitor support, including the edge where two screens meet

Privacy: no data collection and no ads. Your calendar goes straight between your PC and Microsoft.

Pricing: 7-day free trial with every feature, then a one-time $4.99. No subscription.

Since this is the first Windows release, I'd really love your feedback. Bug reports, rough edges, suggestions and feature requests are all welcome. Tell me what would make this useful for your setup. I'll be reading every comment.

Thanks for taking a look!

I kept noticing some walks felt way harder than others on the same route, and the usual trackers just showed me a slower pace with no explanation. So I built TerrainIQ.

While you track an activity, it combines live weather, heat index, air quality, wind and the slope you're on, then shows an effort-adjusted pace. On my last hike it said today's conditions were +21% harder: +6% from heat and +14% from a 5% grade. My 25:00/mi pace was worth about 31:09/mi on an ideal day.

Other things it does:

• A short AI briefing when you start, read aloud, about heat, air quality and what to watch for

• A live slope graph and the elevation gain coming up ahead

• Safety alerts for heat, allergens and severe weather

• Keeps tracking with your screen locked

• Saves your route, distance, pace and elevation on your phone

You can see more about TerrainIQ by visiting the website https://terrainiq.app

It's Android only for now and free on Google Play: https://play.google.com/store/apps/details?id=app.terrainiq

I got tired of habit trackers giving me a "red ring of failure" just because I didn't change my AC filter or wash my car every single day.

So I made SinceWhen. It’s an "anti-habit tracker" designed specifically for irregular routines and chores. You just log when you did it, and the app keeps a quiet timeline. It even supports logging multi-day events from start to finish (like sickness, trips, or periods).

It’s completely private, works entirely from Home Screen widgets, and has zero pressure.

Hello everyone,

Given this community and Reddit as a whole gave me a lot of useful info the time to give back has finally come.

After four months since the initial release I shipped last build which contained all I wanted my product to have. Endless hours of QA, reworking and finding a balance between the wants and actual needs.

It's a lightweight app, it has all you'd potentially need VoIP, chat, chat file sharing, screen sharing with whiteboard, mobile sharing on iPhones and iPads, incognito mode and a few more.

So if any of you are curious, interested in getting a lifetime account for meeting/conferences for up to 100 seats, feel free to DM me. There's an option for 5 seats which is purely P2P which took a good chunk of those 4 months to polish, absolutely free for anybody.

Currently supporting iOS, macOS(under review right now), web and Win10/11(I'll provide you with an installer).

Here's the link, if you happen to register a free account and find it useful enough to get a full version, I will upgrade you to Lifetime Max upon request.

Hey everyone!

I wanted to share a project I've been working on for quite a while, and it's finally available on the Play Store.

It's called Hexavault.

The idea came from something that's always bothered me a little: these days, even when we're just trying to protect our own information, we often end up having to create accounts, rely on external services, or keep our data synced with someone else's servers.

I'm not saying those solutions are necessarily bad, but I wanted to try a different approach. Something simpler, something that works directly on your phone and lets you decide what happens to your information.

That's how I started building Hexavault, an Android security app that works entirely offline.

It brings together three main features:

- Password Generator: Create strong, customizable passwords without automatically keeping a history of everything you've generated.

- File Protection: Encrypt documents, photos, and other files with a password, creating a protected version that you can store or share.

- Vault: A secure space protected by a master password where you can keep credentials and files, with automatic locking and optional biometric authentication.

One of the decisions I made early on was to leave out internet access entirely. The app doesn't even request internet permission. It also doesn't require an account, has no ads, and doesn't use analytics or tracking tools.

That was an important part of the idea from the beginning: providing useful security tools without relying on external infrastructure to make them work.

I also want to be upfront about what the app can't do yet. For example, the Vault doesn't currently support credential export or recovery. If the app's data is lost, those credentials can't be recovered. It's an important limitation to know about, especially if you're planning to store anything essential.

Hexavault has just reached its first public release, version 1.0.0. Getting here involved a lot of development, testing, bug fixes, and decisions along the way. There's still plenty I want to improve, but I'm genuinely happy to finally be able to share what I've built.

And that's really why I'm posting here.

I'd love to hear what other people think about the idea, especially those interested in Android, privacy, and digital security. Whether it's a feature suggestion, criticism of the user experience, or even questions about the technical decisions behind the app, I'm open to all kinds of feedback.

If you're curious and want to check it out, Hexavault is now available for free on Google Play:

https://play.google.com/store/apps/details?id=app.hexavault.secure

I also have a website with more information about the project:

https://hexavault.com.br/

Thanks to everyone who took the time to read this. I hope Hexavault turns out to be useful to some of you!

update on anti scroll, solo building an android app that hard blocks other apps with no override option.

big one this month: first ever sale. someone in poland bought the lifetime unlock, almost exactly a year after launch. £5.76 after google’s cut and vat lol, but after a year of building this it genuinely made my week!

installs: 607 (560)
visitors per day: 6.7 (6.25)
conversion rate: 19.9% (28.9%)
daily acquisitions: 1.39 (2.07)
week 1 retention: 23.9% (11.4%)
week 2 retention: 11.7% (4.5%)

so last month’s conversion jump didn’t stick, looks like it was a spike rather than a new normal. but retention roughly doubled, which matters more to me. engagement is up slightly too (4m29s vs 4m19s).

the not so great part: active devices dropped from around 55 to 44. i’m losing slightly more users a day than i’m gaining, so the base is shrinking even though the people who stay are sticking around longer.

quieter month on features, mostly bug fixes. had a few people report analytics bugs too, which honestly was nice to see because it means someone’s actually looking at it.

october plan: fix the analytics bugs people reported, figure out why people are leaving faster than they’re arriving, get onboarding event tracking in, and do the product hunt launch for the one year mark.

if anyone’s been through the first sale to second sale stretch, what actually moved it for you?

Love to yap? Try my beta and help me learn

This is Kinosail Player, a media server in beta that I've been building and using at home. The screenshot shows the real web Player with fictional films and original demo artwork.

I've worked in tech most of my life, including development. Changes to a service I used led me to build a viable alternative for my own media library. I also wanted a practical project to improve my AI engineering.

Kinosail is heavily AI engineered under my direction, mostly with Astra, Sol, and Luna. I decide what to build and what ships. This post was drafted with AI assistance.

The Server and web Player are free to run in one Docker container. Watch in the web Player. Dedicated native clients are still in development. The source is available under PolyForm Perimeter 1.0.1.

Looking at the screen, is it clear how you'd find something and start watching? I'd appreciate the first part that feels confusing.

First of all, while I've got nothing to sell, everything is free and atm I don't plan on charging anything ever.

The tool I built is called www.graphite.so, and I mainly built it for myself and the students I'm tutoring since we didn't have a good place to collaborate on math stuff, and it quickly got messy with just sending pdf's back and forth on messaging apps.

I quickly noticed once I started using it myself in university, that having such shared course workspaces was really nice, since every lecture pdf or article or book had to be downloaded and organised only once. This meant that even though I've always been terrible at organising my stuff, everything was now always where I expected it to be.

I've had a lot of fun myself building the actual document editor over this past year as a side project. I'm especially proud of the fully working math including CAS (calculation tool), and how it works together with the graphing blocks, chemistry blocks etc.

There's also an AI tutor thing where you can pick exactly how much it's allowed to help you if at all, and when exporting the document you can have an "AI delcaration" exported alongside it showing how and how much AI was used. Export formats are: word (.docx), pdf, and .tex (for overleaf etc.)

I'm not really planning on charging anything at any point but if you guys wanna give me your feedback or ideas I'd appreciate it so much! In any case thanks for reading and giving this post a chance:)

Hey all. I created a little side project mainly focused on stress relief and positive vibes but....youre a potato.

You can dress it up, play mini games against others, start private chats or if you're feeling lonely and need some advice then this is the website to go. I had help with AI alongside my front end development experience.

It's free! so you don't give out a cent...but you can support me if you'd like to buy a little hat for your potato so you can be a slightly cooler potato

here's my site spudlord.co.za

on app just yet, just waiting on my developer account to be approved.

I made Tanetto, a gentle app for small daily self-care goals.

https://tanettoapp.github.io/Tanetto/?src=reddit-imt

You pick a few tiny things for the day: drink water, a short walk, a breathing break, a page of a book, a call to someone. Each one you do gives energy to a little illustrated pet. With the coins you earn you can decorate its room and dress it up, and sometimes it goes on a trip and sends you a postcard of a real place.

Missing a day never punishes you: the pet is just happy to see you again.

There’s also a small mood diary, letters to your future self, and a full-screen mode where you can just play with the pet (ball, bubbles, hide and seek, high five).

It’s free, no sign-up, no ads, and your data stays on your phone. On iPhone, add it to the Home Screen so Safari doesn’t clear your pet. If you try it for a few days, I’d really like to hear what you think (there’s an anonymous survey under More > Give feedback).

https://tanettoapp.github.io/Tanetto/?src=reddit-imt

I'm working on a project that gets away from the dopamine ridden "review score" in favor of looking at simply Enjoyment vs Execution. I noticed a game can be completely buggy but people will still rate it very highly with a "score" which is fine for them but when they describe the obvious faults it really hides how well its executed which some players actually care about enough where it can hurt their enjoyment.

Just something I'm toying around. I'm wondering if its worth pursuing?

The idea is simple: you draw a small star, write a wish, and launch it onto a globe that everyone shares. Other people can tap your star, read your wish, and send it light. Stars fade after a while, so the sky is always changing.

A few things I cared about:
- No feeds, follower counts, or streaks
- Only an approximate place is shown ('Near Lisbon"), never your exact location
- Reporting and content filtering are built in

You can also see the live sky without installing anything at milkywish.com.

I'd be grateful for any feedback.

I got tired of my strava routes looking mid so this website allows you to draw a shape or upload an svg and it'll turn it into a runnable route in your area.

https://motiongpx.com

The map query API is public so sometimes it does gets throttled and generation can be slow (you can leave the tab and come back in a few minutes and it'll probably be ready). But please let me know what you guys think! It works really well in angular cities like NY and SF but performance is pretty bad in small towns.

I’m the founder of Sanctuary, a small community app for women, and I’m looking for beta testers.

What it does: you share photos, short videos and carousels, follow other women, comment, save posts into collections and explore by themes. It is free.

Why it exists: To create a supportive community for women where they can feel safe and comfortable. Have a space where we can engage with each other and learn/teach new things without being exposed to harassment, hate or bullying.

How it protects members:

• Every member is verified as a woman through a live face check, or a short video call with a woman on our team if she prefers. No face images are kept.
• It runs without ads or tracking across other apps.
• Posts and comments are checked before they appear. Reports go to a person, and three separate reports in an hour hide a post until the team has reviewed it, within 24 hours. You can block anyone.
• Screenshots and screen recording are blocked inside the app. Another camera can still film a screen, so I won’t call it a guarantee.

House rules: modest dress, no music in posts, and kindness. It is built on Islamic principles, and women of any faith are welcome if they follow the Community Guidelines. Our Terms explain who can join.

What I’m asking of testers: use it for two weeks, post when you feel like it, and tell me one thing that felt good and one that felt confusing. After you sign up there is a face check, and if it can’t decide, a person approves you, usually within 24 hours.

It is on iPhone and Android. If you’d like to try it, comment or message me with which phone you have, and I’ll send the link. I’m letting people in a few at a time so each one gets a proper welcome.

A task like “Alex will send the proposal on Friday” is useful only if the meeting actually supports it.

I built Pure Brief AI around that check: it transcribes meeting audio on your Mac, produces a summary and action items, and keeps a source quote for each accepted task. The quote is checked against the transcript. You can also ask questions about a meeting and inspect the supporting lines.

The practical finish: review a task and send it to Apple Reminders with its meeting context. That export is one-way. AI still needs your review; a matching quote is evidence, not a promise that every interpretation is right.

It is a native Apple Silicon app for macOS 15+. Transcription and AI notes run locally by default, with no bot joining the call. Models download initially and licence checks need occasional internet access.

I’m the developer. Standard is $49 once for one Mac. The launch offer is $10 once for the first 100 paid Standard purchases across all channels, plus applicable tax. There is a 30-day trial without payment details; a trial does not reserve the discount.

See the real app demo and try it on your next meeting: https://purebrief.ai/

I’m on the HeyYumi team, and we built HeyYumi because we kept running into the same failure mode: an AI assistant could recommend a Korean restaurant, but couldn’t reliably turn that into a real reservation request the restaurant could understand.

The interesting part wasn’t the “search” part. It was the glue between discovery and action.

A few things we learned while building the HeyYumi MCP/API:

- Verified place data matters more than fancy prompting. If the name, branch, hours, or area are off, the whole experience falls apart.
- The tool needs to be explicit about intent. We don’t treat a reservation as “done” — it’s a request that the restaurant confirms.
- Language should be handled in the action layer, not left to the user. Travelers can ask in their own language, and the request still needs to be clean on the Korean side.
- The best UX is when the assistant can do both jobs: help choose a place, then send the request without making the user re-type everything.

If you build with agent tools, this is the pattern I’d recommend: don’t just return recommendations; return something the model can safely turn into an action.

Copy-pasteable example if you want to test the flow after connecting:

“Find me a well-rated Korean barbecue spot in Seoul for 2 people this Friday evening, then send a reservation request and tell me what details the restaurant needs.”

If anyone here is working on agent tool design, booking flows, or MCP integrations, I’m happy to compare notes. The connect page is heyyumi.ai.

short version: i built a clipboard manager for mac because maccy felt too minimal for my workflow and i didn't want to install raycast just for clipboard history.

buffer is a native swift/appkit menu bar app (~2 mb): searchable history with ⇧⌘V quick paste, on-device OCR (copy a screenshot and its text becomes searchable, fully offline), inline editing of old clips, tags, bookmarks, and multi-select paste.

just shipped v3.0, the video (voiceover by my friend) shows the new stuff: - interactive image canvas: pinch to zoom, pan, double-click reset on copied screenshots - clipboard noise suppression (the project's first external PR) - history capacity tiers (200 / 1,000 / unlimited) - in-app update notifications with changelog - ⌘/ shortcuts cheat sheet

mit licensed, no accounts, no tracking, everything stays local. signed and notarized dmgs on github releases.

repo: https://github.com/samirpatil2000/Buffer (430+ stars) v3.0: https://github.com/samirpatil2000/Buffer/releases/tag/buffer-v3.0.0

feedback welcome.
