CafTrack: Optimize Caffeine

Your caffeine, optimised. Doses tuned to your body via Apple Health. Select a Peak Window for your sharpest hours. See it live on your home screen with the new widgets.

Caffeine is a performance tool. Most people never use it like one.

CafTrack shows you how much caffeine is really in your system, when it peaks and when it clears, then plans your day around it. Sharper when it counts, still asleep by midnight.

ON YOUR HOME SCREEN Small and medium widgets show what is active, your next dose and when you are clear to sleep. Most people never open the app to check.

TRACK IN SECONDS Type a drink or scan a barcode, both free. Snap a photo, say it out loud or pick from the drinks library with Pro.

KNOW WHAT IS ACTIVE Live active caffeine, not a daily total. Every dose still working in you, and the exact minute you are clear to sleep.

MEET YOUR AI STRATEGIST A dosing plan for your day that adapts every time you log. Want two coffees in an hour before a deadline? Tell it, and it sets them. Ask it anything: when to dose, what to drink before a run, when to stop for a clean night.

BUILT ON YOUR BODY Link Apple Health and your sleep, heart rate and workouts shape every recommendation. Set a peak window for the hours that matter. Plan gel timing for your runs.

PROTECT YOUR SLEEP Caffeine's half life is over five hours. That 3pm coffee is why you are awake at 2am. CafTrack shows your clear by time, a cutoff that fits your evenings, and a projected sleep chart so you can see the real cost.

YOUR WEEKLY REPORT Every Sunday: intake against target, sleep protection, top drinks, how closely you matched your plan, and what to change next week.

MAKE IT YOURS Set a daily performance target, choose your cutoff, and pick from ten themes.

FREE VS PRO Free: type and barcode logging, live dashboard, home screen widget, five themes. Pro: photo and voice logging, drinks library, AI Strategist, Apple Health, peak window, sleep preview and insights, run fuelling, weekly reports, full trends, five more themes, no ads. 7 day free trial.

Pro pays for the servers and the AI, and that is the job done.

I built this app because my own coffee stopped working. Built and answered by one person.

Your first insight is one drink away.
