We each have this app on our phone and have had multiple sync issues.
- Starting and stopping across devices appears to be broken, and some time counts have turned out to be wildly wrong. Some of this might be user error but the app itself seems dodgy in its performance even when we do simple, same-device operations.
- the data sheets keep showing huge (12+ hour) blocks of sleep time that never happened.
The UI on the sleep/wake toggle is unclear as well, and if you need to correct a resulting mistake then you find a major iOS 9 bug that makes the start-time adjustment very difficult.
Sprout is pushing their newer all-in-one baby metrics app as the solution, so not sure why theyre still selling this on the app store.
