Mirri One turns carbs, insulin, glucose, and real life into patterns you can plan around — CarbIn coverage at a glance, a ShotClock on every dose, and a Playbook of days that worked.
One number that says how your insulin coverage compares to the carbs you've eaten, at your own ratio. The gauge fills as doses land — and the coverage line tells you exactly how many grams you're ahead or behind.
Every dose gets its own ShotClock — the bar fills across the full four hours while the countdown runs to the next milestone, and both change color with the dose's phase: yellow while it's fresh, purple while it works, green through the two-hour check window.
Save real days that worked — meals, activities, doses — each stamped with its CarbIn. Sort them by category, search them, and pin tonight's play to the home screen before life repeats itself.
Your glucose over the purple band with the thresholds that matter, plus a CarbIn calendar that turns every day into a tile — so a drifting week shows up long before a lab result would.
CarbIn rides along on Apple Watch — the live gauge with your carbs and units in one glance, without taking your phone out of your pocket. Doses and meals you log keep the wrist up to date on their own.
When you're low, the app gets out of the way — a simplified screen for treating first and logging after, with no math in the moment.
Insulin needs shift across the menstrual cycle. Mirri One reads cycle data from Health and lines it up with your glucose and CarbIn trends.
End-to-end-encrypted sharing with the people who help — join a diabetes camp by QR code or share 1:1 with a parent. The server only ever sees ciphertext.
A working simulation of the real home screen, running entirely in your browser on made-up data. Demo time runs ~20× faster than real life, so the ShotClock actually counts and doses play out in minutes.
Everything in the phone is simulated with fake data generated on this page — no accounts, no servers, and nothing leaves your browser.
Free to try on iPhone. Your data stays yours.
Mirri One is in active beta. Some features shown on this page and in the demo — including Mirri Relay sharing — are still in development and may change, ship later, or look different in the App Store build. The interactive demo above is a simulation with fake data, not a recording of the shipping app.
