It has been a year and the app still works great! However...

• Android 10 and 11 lack the names. Since Android 9 (28) it seems safe to assume that in future releases that name is the same as the SDK, so 10 = 29, 11 = 30,... 21 = 40.
• Too much green: 28-30 are the same color. Similarly to previous suggestion I propose increasing the yellow minimum every November.
