Caffeine Tracker: Sundown
My cutoff time looks wrong. Check your bedtime and your half-life in Settings. Smoking roughly halves how long caffeine stays with you; hormonal contraceptives and pregnancy roughly double it. You can also set the half-life by hand.
A drink is missing from the list. Tap the + in the log screen to create your own with its own caffeine amount and serving.
I restored my purchase and it did not appear. Make sure you are signed in with the same Apple Account you bought with, then tap Restore on the Pro screen.
Health is not syncing. Open Settings > Apple Health inside Sundown and connect it, then check Health > Sharing > Apps.
