 - The main font for the time is now Audiowide
 - Removed the written out day name and replaced it with steps and bpm
-- Changed the date string to a (for me) more readable string
+- Changed the date string to a (for me) more readable string
+
+Timer function:
+- Touch the right side, to start the timer
+- Initial timer timeout is 300s/5min
+- Right touch again, add 300s/5min to timeout
+- Left touch, decrease timeout by 60s/1min
+- So it is easy, to add timeouts like 7min/3min or 12min
+- Special thanks to the maintainer of the a_clock_timer app from which I borrowed the code.
+
+Todo:
+- Make displayed information configurable, after https://github.com/espruino/BangleApps/issues/2226
+- Clean up code
