Your last coffee decides your night. Halvo shows you how much caffeine is actually working in you right now — and tells you the point after which the next cup starts costing you sleep. Your personal cut-off. Most caffeine apps count milligrams. Halvo works with the caffeine that actually reaches your system: it rises, peaks and fades. Halvo predicts how much of it is still there when you go to bed. YOUR PERSONAL CUT-OFF Everyone clears caffeine at a different speed. Halvo shows you the latest you can have a cup without too much of it still active when you fall asleep. LOG IN SECONDS Add coffee, espresso, tea, energy drinks, soda, mate or your own pre-workout in a few taps. Halvo sums it up automatically and shows how much is still working. ON YOUR HOME SCREEN AND ON YOUR WRIST The widget shows your level and your cut-off without opening the app — one tap logs your favourite drink. In the evening it switches to "lights out" on its own. Plus Apple Watch with a complication for a glance-and-go check. SEE YOUR CURVE Watch caffeine rise, peak and fade on a real concentration curve — and see exactly where you'll land when your head hits the pillow. A MODEL THAT LEARNS YOU — HONESTLY (PRO) With your permission, Halvo reads your sleep, heart rate and HRV from Apple Health and learns your personal caffeine half-life over time. Here's what makes it different: when the signal in your data is too weak to be sure, Halvo says so and keeps using the population value — instead of faking precision it doesn't have. WORKS WITH YOUR WEARABLES (PRO) Apple Watch, Oura, Whoop, Garmin — anything that syncs sleep and heart data to Apple Health. Halvo never connects to those services directly; it only reads what's already in Apple Health. PRIVATE BY DESIGN Your intake and health data are processed on your device. Halvo doesn't sell your data. FREE & PRO Logging caffeine, seeing your curve, using the widget and finding your cut-off are free. Halvo Pro adds the personal learning model and the nightly sleep analysis.
