What might your next coffee add at bedtime? Onset estimates caffeine remaining at your chosen bedtime from the drinks you log. Check a possible drink first, adjust its amount and time, then log it only if you've had it. CHECK BEFORE YOU LOG Compare your logged drinks with a temporary What if forecast. Adjust caffeine amounts with the dial, choose a serving and set the drink's time. KEEP YOUR DAY TOGETHER See today's drinks beneath your forecast. Save your usual drinks, review earlier entries, and edit or remove a log. EXPLORE YOUR OWN PATTERNS Review caffeine timing alongside optional Apple Health sleep records and morning ratings. Personal comparisons need enough recorded nights; a clear pattern may never appear. MAKE IT YOURS Choose Ember, Matcha, Midnight or Obsidian, with light and dark appearances. PRIVATE BY DEFAULT Your history stays on your iPhone. No account, cloud sync or tracking. Drink search works offline. Apple Health sleep access is optional and read-only. Forecasts are estimates based on recorded drinks and model assumptions, not measurements or predictions of how you will sleep. Feedback and support: inder@doodlestudio.io
