Questions, answered

Everything you might wonder about caffeine and sleep.

How does Matcha know when it's safe to sleep?
Matcha models caffeine's half-life in your body (about 5–6 hours, adjustable to your sensitivity) and counts down to the moment your level drops below a sleep-safe threshold before your chosen bedtime.
Is Matcha free?
Yes — Matcha is free to download with real-time caffeine tracking and logging. Matcha Pro unlocks the weekly Sleep Score, unlimited history, all themes, custom drinks and every widget.
Does it work with Apple Health and Apple Watch?
Absolutely. Matcha syncs caffeine and sleep two-ways with Apple Health, and you can log a drink or check your status right from your Apple Watch.
How accurate is the caffeine database?
Matcha includes 2,300+ drinks and brands with researched caffeine values, plus size adjustments. You can also create custom drinks with your own caffeine amount.
Will it nag me with notifications?
Never. Smart cut-off alerts are optional and send at most one gentle reminder a day — when it's time to stop caffeine for the night.
