WhatsNew:

The dev lost the signing key, you will have to un- & re-install to update from 1.8.2 or below. F-Droid & IzzyOnDroid have verified to their best abilities this change should be legit, see https://github.com/JustDeax/ComposeStopwatch/issues/4

Find the dev's notes at https://justdeax.github.io/ComposeStopwatch/key-rotation

- Added settings dialog, more settings!
- Added vibration enable
- Added autostart enable
- Added themed icon
- Changed minimum android
- Improved and faster stopwatch saving

Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos.

Download Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
