MyCaffeine - Caffeine Tracker

MyCaffeine helps you track your daily caffeine intake and understand how it affects your body — from your morning coffee to your last drink before bed.

Log a drink in seconds, see exactly how much caffeine is in your system right now, and get a clear picture of how it builds up and fades throughout the day.

Caffeine Tracking
- See the current caffeine level in your body, updated in real time.
- A live prediction graph shows your caffeine rising and falling across 24 hours, centred on now.
- Caffeine now absorbs gradually rather than spiking instantly, so the curve better matches how you actually feel.
- Forecast how much caffeine will still be in your system at bedtime.
- A heads-up before you log a drink that would push you past your daily or bedtime limit.

Water Tracking
- Track your hydration alongside your caffeine, with a daily goal and a rolling 24-hour graph.
- A hydration status label, from Dehydrated to Well Hydrated.
- Water from every drink you log counts automatically.

Apple Watch
- Log drinks and water straight from your wrist.
- Check your caffeine, hydration and daily total at a glance.
- Complications for your watch face, kept in sync with your iPhone.

Health Analysis
- See how your caffeine lines up with your sleep, heart rate and activity, using data already in Apple Health.
- Plain-language findings explain what your data actually shows.

Trends & History
- Track your intake, weekly patterns and bedtime caffeine levels over time.
- Findings on every chart explain what you're looking at, in plain language.
- Brand Ranking shows which brands you drink most, and what they add up to.
