How much, how long ago, what’s still working. Mirri One puts the answers on one screen and tunes your insulin-to-carb ratio against what actually happened — so more of your day is something you can see, not guess.
One number for how your coverage compares to the carbs you’ve eaten, at your own ratio. The gauge moves as doses land; the line below shows how many grams you’re ahead or behind.
Every dose gets its own four-hour clock, so what’s still working is on the screen instead of in your memory. The color changes with each phase — fresh, working, check window. What you do with that is between you and your care team.
Some days just work. The Playbook saves them, each stamped with its CarbIn, so the next pizza night starts from the one that went well instead of from scratch.
A week can drift before anything feels different. A CarbIn calendar turns every day into a tile, so the drift shows up early — while it’s still easy to act on.
The same CarbIn gauge, on your wrist — your carbs and units in one glance, no phone out of your pocket. Doses and meals you log keep the wrist current on their own.
Straight from the wrist
Many people notice their glucose moves with their cycle. Mirri One lines cycle data up with your CarbIn and shows the average for each phase, so the pattern is something you can see rather than something you suspect.
When you're low, math is the last thing you can do. Low Mode gets out of the way — a simplified screen for treating first and logging after, with nothing to calculate in the moment.
End-to-end-encrypted sharing with the people who help. Join a camp by QR code or share 1:1 with a parent — the server only ever sees ciphertext.
Real captures from the app on iPhone — not mockups. Scroll across.
A working simulation of the real home screen, in your browser, on made-up data. Time runs ~20× faster so doses play out in minutes. It’s a small slice — the real app does considerably more.

Free to try on iPhone and Android. 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 Mirri One Mini demo above is a simulation with fake data, not a recording of the shipping app.
