Kairo turns your logged doses into a living picture — a pharmacokinetic model of your medication, your full peptide protocol, training, labs, and an AI that knows your numbers. All on your device.
No account. No sign-up. Your health data stays in protected local storage on your iPhone.
Weekly pens or daily orals — Zepbound, Mounjaro, Wegovy, Ozempic, Rybelsus, Saxenda, Trulicity, compounds and more. Streaks, reminders, and a home-screen widget with your next-dose countdown.
A population pharmacokinetic model of every logged dose — watch levels build, overlap, and taper across 7-day to all-time views, with an optional forecast.
Track every compound on one schedule — doses, cadence, adherence, and injection-site rotation that remembers where you last pinned, per compound.
Upload any lab PDF or photo. You review every extracted value before it saves. 83 biomarkers with plain-English explanations and trends over time.
Equipment-aware strength plans built to help you hold onto muscle while the scale drops, with PR tracking and recovery-aware guidance.
An assistant grounded in your own logged data — doses, weights, recovery, protocol. Optional, consent-gated, and off until you turn it on.
Kairo's curve isn't a mood ring. Each medication's absorption and elimination parameters come from FDA prescribing information and peer-reviewed research — and every source is linked inside the app.
Kairo launches straight into the app — there is nothing to sign up for. Health tracking records use protected local Core Data on this device. RevenueCat processes a purchase identifier for subscriptions, and disclosed content is sent online when an AI feature makes a request.
Prices in USD; local pricing set by the App Store. Subscriptions renew automatically until cancelled in your App Store settings.
Kairo is built by one person, for this community. The public board is where the next feature gets decided — post an idea, upvote what matters, and see what's planned.
