CafTrack: Optimize Caffeine

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.

MEET CAFFI, 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 Caffi, and it sets them. Ask anything: when to dose, what to drink before a run, when to stop for a clean night. New to the app? Caffi shows you around, one screen at a time.

KNOW WHAT IS ACTIVE
Live active caffeine, not a daily total. Every drink sits on your curve, so you see what is still working in you and the exact minute you are clear to sleep.

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

ON YOUR HOME SCREEN
Small and medium widgets show what is active, your next dose and when you are clear to sleep. No need to open the app to check.

BUILT ON YOUR BODY
Link Apple Health and your sleep, heart rate and workouts shape every recommendation. Drag your peak window to the hours that matter and Caffi times your coffee to hit them. Plan gel timing for your runs.

PROTECT YOUR SLEEP
Caffeine's half life is around 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 a plan for next week you can apply in one tap.

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

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