Tell me when they update their app for the new iPhone. Tell me when they decide that when there's a bug that makes the calorie tracking almost useless for existing users they won't just fix it for new people and pretend it didn't happen, instead actually telling users who were affected and lost months and months of data.
Tell me when they decide to integrate into HealthKit.
Or maybe just fixing a bunch of the weird little UI things that have been wrong with the app since the iOS 7 version launch.
When FitBit pretends to care about their software they might be worth considering again. Right now they're behaving like just another hardware manufacturer who only makes half-assed attempts at software.
