FatWatch 2.1, released last week, has two problems:
FatWatch 2.1.1, submitted to the App Store last night, fixes both of these problems. The first one was mostly an oversight; I didn’t realize how many people were using older versions of iOS. The second was a stupid mistake; my test data has very few completely empty days, so I didn’t notice the problem until it was too late.
2.1.1 is a very minor update, let’s hope it doesn’t spend a long time in review.
