Caffeine Wise is a personal caffeine clock. Log what you drink, see how much caffeine is estimated to remain in your system, and decide whether another cup still fits tonight.
No account. Core tracking works on your device, even offline.
WHAT YOU CAN DO
• Log coffee, tea, energy drinks, and custom drinks with time and serving • Watch remaining milligrams on a live clock, including a bedtime estimate • See whether you are still on track for the bedtime threshold you set • Review daily and longer-term patterns on device — not uploaded to use the charts • Get optional reminders: daily log, threshold, inactivity, or a bedtime alert • Read short, sourced articles on caffeine and sleep • Ask Caffio AI before the next cup (optional). Engine numbers stay the source of truth for milligrams • Optionally write today’s caffeine to Health Connect. The app works fully without it
BUILT FOR CLARITY
Estimates use a half-life model you can personalize. Skip the questionnaire and change half-life, threshold, and bedtime anytime. Catalog caffeine values are not invented; Caffio AI is not allowed to make up doses.
PRIVACY
Your drink log, profile, and estimates stay on this device unless you export them or use an optional live AI feature. We do not sell your data. Ads, if shown, never receive health, profile, or consumption data. Analytics are off unless you opt in.
Caffeine Wise is for information and self-tracking only. It does not diagnose, treat, or prevent any condition, and estimates are not lab measurements. If you are pregnant, take medication, or have a medical condition, talk to a qualified clinician.
