Coffee keeping you up at night? Cira tells you the exact hour of your last cup, worked out from your bedtime and your body, so your coffee stays out of your night. Most trackers count the cups you drank. Cira counts what is left: caffeine climbs for about 45 minutes, then leaves at a rate set by your own metabolism, not by an average adult. Between a fast metabolism and a slow one, the difference is hours of sleep. WHAT YOU SEE FIRST • Active caffeine right now, in milligrams • The hour after which a normal cup starts costing you sleep • Whether tonight holds, and when you will be clear • The whole day as one curve: where the peak was, where it goes next TUNED TO YOU Smoking clears caffeine almost twice as fast. Contraceptives and pregnancy slow it down. After 65 it slows again. Cira applies all of it, and if you know your own half-life you can set it by hand. SLEEP JOURNAL Rate your night in one tap and note how you feel during the day. Connect Apple Health and Cira places your Apple Watch sleep next to the caffeine you logged, so you see what coffee really does to your nights. BEFORE YOU DRINK Check any drink at any hour before you pour it. Cira puts tonight with it and without it side by side. The log-it-anyway button never disappears: the job is to name the price, not to take the choice away. WHO IT IS FOR People who drink coffee after lunch and then lie awake. People cutting down who want to see what changes. People who take an energy drink before training — and get up early. FREE FOREVER Logging drinks, active caffeine right now, your last-coffee hour, tonight's verdict, the daily curve, the reminder before your last cup, and the sleep and mood journal. PREMIUM The before-you-drink check for any drink and hour, the full physiology model, journal insights and Apple Watch sleep analysis, the hours your caffeine is actually working, history beyond a week, your own drinks, and a step-by-step plan to cut down. Cira gives an estimate, not a medical diagnosis. It uses a standard one-compartment pharmacokinetic model with first-order absorption. That is a good approximation, but no app can measure your blood.
