Wattz is an open-source (MIT) Android app by Dustin Brown. The APK we host is 684 KB, it needs Android 9 or newer, and it declares 5 permissions.

The file on this page is Wattz 1.20, 684 KB, and it installs on Android 9 and newer.

We compared the signing certificate of this build with the certificate recorded the first time dubrowgn.wattz 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 declares 5 permissions, none of which cover contacts, location, SMS, the camera or the microphone.

Its licence is MIT. We took this build from F-Droid, and the source for this exact version is linked below.

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.
