Magnet Mode (thank you Stubenhocker on the rebble discord). When magnet mode is on, the balls get caught in gravity mode just like the real magnetic ball bearing watches (unless you get them to fly past too quickly)
Fixed bug that battery bar on rectangular mode was always showing 100%. Tweaked Gravity sensitivity settings, and changed gravity mode to work better on Rectangular tracks (the ball bearings now settle in the corners).
Rectangular tracks mode added (rectangular watches only). Let me know if you see any bugs
New setting to choose how fast or slow the balls move in Gravity Mode, by changing the retained velocity/friction level
Tweaked Gravity mode slightly
Now with Gravity Mode (not on Aplite). Also tidied up the code
Initial release, let me know if there's any bugs
