Curfew: Caffeine Tracker
Last coffee time for sleep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know when caffeine clears before bed. Log coffee in one tap — sleep-safe countdown included.
Afternoon coffee? Curfew tells you exactly when caffeine will clear so you can sleep well — without guesswork or guilt.
Coffee, espresso, tea, energy drinks: log any caffeinated drink in one tap and watch your personal sleep-safe time update in real time. Curfew models how caffeine actually decays in your body using half-life science, not a flat "cutoff hour" guess, so the countdown adjusts to what and how much you drank. It's a calm, judgment-free companion for anyone who loves coffee in the afternoon but still wants to fall asleep on time.
KEY FEATURES:
• Sleep-safe clock — see the exact time your caffeine will clear
• One-tap logging for coffee, espresso, latte, tea, and energy drinks
• 8 built-in drink presets, sized small/medium/large
• Real caffeine decay math based on half-life — not a gimmick counter
• Gentle curfew reminders before your personal caffeine cutoff
• 7-day insights to see when and how much you're really drinking
• Lock Screen + Home Screen widgets with live caffeine level (Pro)
WHY CURFEW:
• On-device — your drink log stays private, never sold or shared
• Built for real routines: log a coffee in under 5 seconds
• Designed around sleep science, not caffeine myths
• Native widgets and HealthKit integration, no clutter
CURFEW PRO:

• Full history beyond 7 days
• Custom drinks and adjustable half-life (4–7 h) to match your own sensitivity
• Lock + Home Screen widgets with live caffeine level

PERFECT FOR:
• Coffee and espresso lovers who don't want caffeine wrecking their sleep
• Shift workers and night owls tracking a moving bedtime
• Anyone sensitive to caffeine who keeps drinking "just one more" too late
• People already using a sleep or energy tracker who want the missing caffeine piece
• Parents and students managing energy dips with coffee, safely
ACCESSIBILITY:
Curfew supports VoiceOver, Dynamic Type, and full Dark Mode, so the sleep-safe clock and drink log are easy to read and navigate for everyone.
