Caffeine Tracker vs Progress Hub

Doppio is a native caffeine tracker that estimates how much caffeine is still in your system right now — and how it fades over the hours ahead. Log drinks with a tap, watch your levels decay on a personalized metabolism curve, and finally answer the question that matters: is that afternoon coffee going to keep you up tonight? Doppio is free for the core functions. Track your caffeine, see your metabolism curve, and brew better coffee without paying anything — ever.

They come from a standard half-life model adjusted by the answers you give during setup — not from measuring your body. Doppio is not a medical device and does not provide medical advice; talk to a clinician about specific health concerns. Your data stays on your device and in your private iCloud unless you enable Apple Health sync. Analytics are optional and never include your caffeine logs, health samples, or notes.
