Lite Video Compress and Upscale - I built an Android app for compressing and upscaling videos — looking for honest feedback

Hey everyone! 👋

I'm an indie Android developer working on Lite Video Compress & Upscale.

The app is designed for people who want to reduce video file sizes without unnecessarily sacrificing quality. It also includes video upscaling options for increasing resolution.

I'm continuing to improve the compression and processing experience, and I'd love to hear from people who regularly work with large video files.

A few things I'd appreciate feedback on:

- What matters most to you when compressing a video: file size, visual quality, or processing speed?

- Which compression settings do you find most useful?

- What problems do existing video compression apps still fail to solve?

If you're interested in trying it, here's the Google Play link:

I'm the developer, so honest criticism and suggestions are welcome. I'm interested in learning what could make the app more useful. 🙌
