We compared the signing certificate of this build with the certificate recorded the first time dev.calyptra.pappus 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 4 permissions, including access to precise location and approximate location. Android asks you to approve those the first time the app needs them.
Its licence is GPL-3.0-or-later. 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 only works with one specific server, which 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.
