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.



Obtainium already works with the GitHub releases, and the README has a one-tap link for it.
There’s no edit feature, but the viewer’s Share button hands the file to any app that accepts it so that should work for what you said.
Brilliant, thanks - my obtainium attempts had “.git” on the end. Looks great, the share feature is exactly the use case I was looking. Only looking for it baked in because android’s share feature is fairly poor.
Glad Obtainium works now! Fair point on the share sheet, a button that only lists the apps that can open that file type would be nicer.
