SipSense: Caffeine Tracker

That 4 PM espresso is why you're staring at the ceiling at midnight. SipSense shows you exactly how much caffeine is in your system — and when to stop. ONE-TAP LOGGING A built-in beverage library covers coffee, espresso drinks, tea, energy drinks and sodas. Log your usual in one tap, or add custom drinks. DAILY LIMIT RING Watch your intake fill a progress ring toward the commonly referenced 400 mg daily guideline. CAFFEINE DECAY See a live estimate of caffeine leaving your system through the day, based on its typical half-life. SMART CUTOFF TIME Tell SipSense your bedtime and it calculates when your last caffeinated sip should be. TRENDS Weekly and monthly charts reveal your patterns — which days spike, and how your habits change. PREMIUM Unlock trends, decay visualization, unlimited favorites, custom beverages and full history with a monthly subscription. PRIVATE BY DESIGN Everything you log stays on your device — no account, and your caffeine data is never uploaded. Free users see ads, which may use your device's ad identifier if you allow it; Premium removes them. SipSense is for personal tracking only and does not provide medical advice. Auto-renews monthly. Cancel anytime in your Apple ID Subscriptions settings. Any unused portion of the introductory offer is forfeited when you purchase a subscription.
