It works without connecting sleep data. LEARN FROM YOUR ACTUAL SLEEP WITH CAFFEINE PRO Connect Apple Health sleep data or record your sleep manually. Caffeine Pro helps you review how your drink timing and actual sleep line up over time. • Review each night's saved bedtime, actual sleep, and estimated caffeine • Correct sleep entries and reversibly exclude nights from your patterns • Explore private patterns as sufficient reviewed history becomes available • Receive a conservative bedtime target and finish-by window when the evidence supports them • Try a guided earlier-cutoff experiment and review what happened Collecting nights is the start. Recommendations depend on the amount and quality of your history. Pro does not promise a personal answer after a fixed number of nights. YOUR HISTORY STAYS ON YOUR DEVICES Use Caffeine Mate without an account. Your caffeine history, settings, and optional Pro sleep data stay on your devices. Apple Health access is optional and controlled by you. Estimates and observed patterns are for planning. They are not body measurements or medical advice. Sleep patterns do not establish cause and effect, and individual caffeine response varies. Download for free, then choose Caffeine Pro Lifetime or Annual after your personal onboarding preview. Lifetime is a one-time purchase with Family Sharing. Annual includes a 7-day free trial for eligible Apple accounts, then renews automatically each year unless cancelled. Pro unlocks continued tracking, live forecasts, sleep insights, Apple Health syncing, Apple Watch, and widget logging. Your saved history and data export remain accessible without an active plan.
