Matcha vs Caffeine mg

Love coffee? Sleep great anyway. Matcha is the caffeine tracker that tells you when to stop. Log your coffee, matcha, tea or energy drink in a tap, and Matcha shows your personal coffee cutoff: the last time you can have caffeine and still be low on it by bedtime. Most caffeine apps just count milligrams. Matcha answers the questions that matter: "Can I have another coffee?" and "Will this hurt my sleep tonight?"

See when you're "Sleep-ready at 10:50 PM" • Tonight's forecast: Great, Good, Restless or Rough sleep ahead • A friendly reminder 30 minutes before your cutoff ALWAYS IN VIEW • Home Screen and Lock Screen widgets show your cutoff and which drinks still fit tonight, in StandBy too • Live Activity: a countdown to your cutoff on the Lock Screen and in the Dynamic Island • Siri & Shortcuts: "Log a coffee in Matcha" or "When can I have coffee in Matcha?"
