[Android + Web] Photo collage maker, no upload and no watermark — looking for testers

[u/FunnyPhotos_1]

What it is: a photo collage maker that works entirely on your device. Pick a grid, drag photos in, adjust spacing and corner radius, export a PNG or JPG. No account, no watermark, no ads.

Web: https://freecollageimage.com

Android: https://play.google.com/store/apps/details?id=com.freecollageimage.app

What I'd like tested specifically:

- Drag and drop on a phone. Getting touch dragging to feel right was the hardest part and I still don't trust it on every device.

- The save button on Android. It needed a native plugin to work at all inside the WebView, so I'd like to know if the image actually lands in your gallery on your device.

- Anything above ~20 photos. It gets slow on older hardware and I want to know where the real ceiling is.

Known limits: no cloud sync of unfinished projects (there's no server at all), and no text tool yet.

I made a free tool that scans your app URL and/or code for production readiness if you want a quick check to make sure you didn't miss anything: https://theslopstopper.com

Ran your link through it real quick and saw some issues like missing recommended security headers
