Everything Mirri One surfaces from the day you already live.

CarbIn

One number for coverage

How your insulin coverage compares to the carbs you've eaten, at your own ratio. The gauge fills as doses land; the coverage line says how many grams you're ahead or behind.

22g carbs · 3.80 U 20g ahead at 11.0 g/U

ShotClock

Every dose on the clock

A bar that fills across the full four hours, a countdown to the next milestone, and a color for every phase — yellow fresh, purple working, green through the check window.

The Playbook

Days worth repeating

Save real days that worked — meals, activities, doses — each stamped with its CarbIn. Search, sort by category, and pin tonight's play to the home screen.

Trends

The month at a glance

Your glucose over the purple band with the thresholds that matter — 250, 180, 100, 70 — plus average and time in range for the last 30 days.

CarbIn calendar

Every day, a tile

Each day's CarbIn becomes a tile on a calendar — so a drifting week shows up long before a lab result would.

Apple Watch

The gauge, on your wrist

The live CarbIn gauge with your carbs and units in one glance — no phone required. Logs from the phone keep the wrist current on their own.

Low Mode

Treat first, log after

When you're low, the app gets out of the way — a simplified screen with no math in the moment. Log it once you're back.

Cycle tracking

Cycles, correlated

Insulin needs shift across the menstrual cycle. Mirri One reads cycle data from Health and lines it up with your glucose and CarbIn trends.

Mirri Relay Coming soon

Share, 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.

Streaks

Showing up, rewarded

A streak for logging the day you actually had — not for perfect numbers. The flame is for consistency, nothing else.
