Caffeine Mate: Coffee Tracker
Sleep Forecast & Drink Log
Free · In‑App Purchases
Trying to cut back on caffeine? See what you’re drinking and how much remains at bedtime. Let's do this.
Can I have another coffee before bed?
Log your drinks with Caffeine Mate, then check your estimated caffeine now and at bedtime. Preview your next coffee, tea, matcha, or energy drink before you add it to your day.
TRACK YOUR DRINKS
• Log coffee, espresso, tea, matcha, energy drinks, or a custom caffeine amount
• Find familiar drinks, save favorites, and reuse recent entries
• Review and edit your drink history
• Log from iPhone, Apple Watch, or an interactive widget
PLAN YOUR NEXT CUP
• See your modeled caffeine estimate now and at your chosen bedtime
• Compare your bedtime estimate with the target you set
• Preview how another familiar drink would change that estimate
• Adjust your processing settings, bedtime, and target
• Follow the caffeine curve and inspect the formula behind the estimate
The forecast uses your drink log and settings. 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.
