Last Coffee answers one question: "Can I drink this now, or will I regret it tonight?" It's not a tracker. It's a sleep-protection instrument. The home screen shows your verdict — GO, CAUTION, or STOP — based on how much caffeine will still be active when you fall asleep, not just how much you've drunk. WHAT IT DOES • A verdict-first home screen, written in plain English. "Your system is clear." "Hold the line." "Caffeine is likely following you to bed." • A dynamic cutoff time. As you log drinks during the day, the safe coffee window slides earlier. You always know the latest minute you can still add one more. • A live curve. See your caffeine over time, with your bedtime marked. Tap to peek into the math. • A widget for your home screen. Caffeine remaining + cutoff time, glanceable. • A daily reminder. 30 minutes before your safe window closes, the app gently nudges you. One notification a day, max. Never on first launch - only when you opt in. THE MATH Caffeine has a 5-hour half-life and a 45-minute absorption ramp. A coffee drunk right before bed is the worst kind - it absorbs while you're trying to fall asleep. Last Coffee accounts for the worst-case load during the sleep onset window, not just a snapshot at bedtime. Three strictness profiles (Relaxed, Normal, Strict) match different sensitivities. YOUR DATA Stays on your iPhone. No accounts. No analytics. No third-party SDKs. No cloud sync. Apple handles in-app purchases via StoreKit; the app never sees your payment details. LAST COFFEE PRO (one-time, $2.99) Unlock the drinks you actually drink: Matcha, Pre-workout, Coke Zero, and any custom amount. NO ADS. NO SUBSCRIPTION. NO TRACKING.

v1.1 - see what each drink will do, before you log it. · Pre-log preview shows projected bedtime mg + verdict as you slide · Past-bedtime now reads STOP regardless of math (no more accidental "GO" advice when you should be asleep) · "Max safe" threshold labeled on the curve and home view · Decaf added to the drinks menu · Normal tier now treats 95mg pre-bed as STOP (was CAUTION) · Yesterday's drinks no longer leak into today's view Math is the same; the math is now visible at decision time.
