About
Most people drink caffeine every day, but almost nobody manages it.
CafFix changes that.
Tell us your goal, better sleep, sharper energy, or just staying within your daily limit, and we'll build a caffeine plan around your body, your schedule, and your life.
Your personalized caffeine limit:
Forget the generic "400mg a day" advice. CafFix calculates your exact daily limit based on your body weight and age, so your goal actually means something.
Know when to stop automatically:
Based on your bedtime, CafFix tells you your caffeine cutoff time every single day. So you stop guessing why you can't fall asleep.
Three goals. One app.
* Sleep Better - optimize your caffeine cutoff for deeper rest
* Optimize Energy - time your intake for peak performance
* Just Track It - stay under your daily safety limit
Always with you:
Live Activities on your lock screen and a home screen widget mean you never have to open the app to know where you stand.
Built around your week:
Different bedtime on weekends? CafFix adapts your caffeine windows day by day.
Finally, a caffeine tracker that works as hard as your morning coffee.
