Numerus is an open-source (GPL-3.0-only) Android app by Konstantin VERNER. The APK we host is 15 MB, it needs Android 9 or newer, and it declares 3 permissions.
The file on this page is Numerus 2.0, 15.21 MB, and it installs on Android 9 and newer.
We compared the signing certificate of this build with the certificate recorded the first time xyz.numerus entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the app does.
The manifest inside the APK declares 3 permissions, none of which cover contacts, location, SMS, the camera or the microphone.
Its licence is GPL-3.0-only. We took this build from F-Droid, and the source for this exact version is linked below.
F-Droid, who build and sign this package, flag it: it relies on a network service that is not open source. We pass that on as they recorded it — we have not tested the app ourselves.
We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
