Kepler-App is an open-source (GPL-3.0-only) Android app by AntonioAlbt. The APK we host is 65 MB, it needs Android 7.0 or newer, and it declares 10 permissions.

The file on this page is Kepler-App 2.18.2, 64.86 MB, and it installs on Android 7.0 and newer.

We compared the signing certificate of this build with the certificate recorded the first time de.keplerchemnitz.kepler_app 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 10 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.
