Hypatia is the worlds first FOSS malware scanner for Android. It is powered by ClamAV style signature databases.

This is a fork of the original (and discontinued) app, which is still looking for maintainers.

Features

Near zero battery impact: you'll never notice any impact on battery at all
Extremely fast: it can scan small files (1MB) in 20ms, and even large files (40MB) in 1000ms.
Memory efficient: with the default databases enabled it uses under 120MB.
Regular scan: allowing selection of /system, internal storage, external storage, and installed apps
Realtime scanner: can detect malware in realtime on write/rename in internal storage
Completely offline: Internet is only used to download signature databases, files will never ever leave your device
Persistence: will automatically restart on boot/update
Tiny codebase: coming in at under 1000 sloc, it can be audited by even someone with basic programming experience
Minimal dependencies: the app only uses libraries when necessary
Signature databases can be enabled/disabled at the users demand

WhatsNew:

- chore: security disclaimer
- feat: share scan feature
- feat: add new database urls and make codeberg default
- enhancement: database downloading conditions updated and fixed unnecessary or missing updates
- enhancement: More modern notification UI
- enhancement: Warn if signing key is wrong/not matches
- dev: update gradle to 8.9 and java to 21
- dev: drop Android 4 support
- dev: support Android 14
- dev: new logger mechanism for better/async debugging and logging
- dev: new AppCompat implem

Download Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
