We compared the signing certificate of this build with the certificate recorded the first time eu.roggstar.luigithehunter.batterycalibrate 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 no permissions at all.

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.

The most recent release upstream is from Sep 17, 2021, over 5 years ago. It still installs; it is simply not being updated.

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.
