GitHub · Google Play

Opens PDF, Word, Excel, PowerPoint, photos, video, audio, Markdown and code, all rendered on the device. About 5 MB, one build for every processor, Android 8.0 and up.

Search works in every document type. PDF text selects, copies and reads aloud to a screen reader, and there is a night mode that turns the paper black and leaves most photographs alone.

Its permissions page is empty and the manifest has no INTERNET so it can't open a network connection. Files reach it through the system picker, an Open-with intent, or a folder you grant once. The About screen asks Android what the app requests and shows you the result.

Not an editor. Legacy .ppt does not open. Complex PowerPoint renders approximately.

I will be in the comments today, so ask away, including why it isn't on F-Droid yet.

A lot of it was written with AI, yes, under my direction, and every push runs the test suite in CI.

The no-permissions part doesn't rest on trusting the code, though. The build fails if a permission is added, the About screen shows what Android says the app requests, and it's MIT, so the code is there to read.

If anything in it looks wrong, open an issue and I'll look into it: https://github.com/mokshablr/gander/issues
