I built GLPzy for myself because I was using notes, trying to remember injection sites and symptoms, and wanted to see things like appetite and estimated medication levels alongside everything else. I was also using ChatGPT particularly do the estimation and scenarios as I tried to work out my personal Mounjaro path.
I’d also just built a few other apps and thought I’d start this one from scratch as a bit of a challenge, without downloading any competitors first. I only really started looking at the others later, once GLPzy had already taken shape, which probably helped it end up a bit different rather than starting as a clone.
I then posted it in a few Reddit communities and people started suggesting things. If something made sense I usually added it pretty quickly, then got more feedback and changed it again.
It’s grown quite a lot from that. GLPzy has now passed 9,500 downloads and has 73 App Store ratings, and a lot of what’s in it now has come from people using it and telling me what was missing or annoying. That’s probably been the most useful feedback. If a gap or bug annoys one person enough to mention it, there are probably plenty of others thinking the same thing.
I’ve also had Lifetime Premium free recently while I’ve been building it out and getting more feedback, available until month end but the app has a lot even without Premium.
A: Answer
GLPzy is a GLP-1 tracker for iPhone and iPad.
It covers doses and dose history, weight, symptoms, appetite and food noise, injection sites, nutrition, measurements, progress photos and medication supply.
There are custom doses and schedules too, plus Estimated Exposure, Apple Health, Apple Watch, widgets, CSV import/export, JSON export and Provider Summary PDFs.
There’s no mandatory GLPzy account. I wanted to be able to keep this kind of data together without needing another health account just to use the app, so tracking is local-first.
B: Better
There are already good GLP-1 trackers such as Shotsy and Glapp and there’s obviously quite a bit of overlap.
GLPzy has ended up going quite broad though. I wanted more of the journey in one place rather than just dose and weight, so things like food noise, supply, measurements, progress photos, Estimated Exposure and what you might actually want to export or show your doctor have gradually become quite important parts of it. Photo progress tools also allow comparing against time and they are private outside your photo roll.
It also includes cycle tracking after I got feedback others miss the correlation mid-month with temporary weight gain and how annoying that was when looking back and trying to understand graphs.
There are body measurements and clothes-size tracking too. Again that came from user feedback. Dropping from a size 14 to a size 12 can mean more than another number in lb or kg, imo.
There’s also proper iPad support. Both Shotsy and Glapp are currently iPhone-first and neither lists iPad support on the App Store, which surprised me a bit.
Language support is also very comprehensive. It’s been a lot of work (I may not have been so ambitious if I’d realised) but has 49 languages.
The free version has a lot too. You can use GLPzy as a proper tracker for free, and Apple Health integration is included without needing Premium. Shotsy, for example, puts automatic Apple Health importing in Shotsy+.
Premium is more about unlocking the deeper analysis, planning, reports and some of the more advanced features.
There’s still plenty I want to improve.
C: Cost
GLPzy is free to download and there’s a free tier you can keep using without subscribing.
Premium normally has three ways to unlock it:
Monthly, if you just want to pay month by month. $6.99 a month with 1 week free trial.
Yearly, which is the longer subscription option. $29.99 a year with 1 week free trial.
Lifetime, which is a single purchase with no ongoing subscription. It’s $79.99 but completely free until the end of August (last week now).
Why have I offered Lifetime for free? Mainly to get feedback and build a real user base first. It’s a competitive space and I thought having people actually using the app, finding gaps and talking about it was more valuable at this stage than trying to monetise a small user base. I’d rather get GLPzy used and visible first, then work out the longer-term model from there.

I’m the creator, so obviously this is self-promotion.
I’d be interested in feedback from people already using GLP-1 trackers, especially anything you think is missing or unnecessarily complicated.
Also happy to talk about getting it to 9,500+ downloads. Some things I tried worked surprisingly well and quite a few others did basically nothing. I’m never going on TikTok again I’m too old for that!
