A calm, glanceable companion for the numbers you check forty times a day — sometimes at 3 a.m. with shaking hands. One quiet number, your whole history, gentle alerts.
Coming to the App StoreLumi is a calm display companion for the Dexcom G7 family of continuous glucose monitors. It listens quietly alongside the official app and turns your readings into something you actually want to look at — soothing, legible, and entirely yours.
One big, calm number with a soft glow that breathes — your trend and the last three hours, at a glance.
A chart you can pan through everything your sensor has ever told you, plus time-in-range and a report for your care team.
Low, high, and a gentle wrist tap for urgent lows — guidance, never sirens on the screen.
Apple Watch complications, home- and lock-screen widgets, and a Live Activity so the number is always one look away.
No account. No servers. Your data never leaves your device.
Lumi is not a medical device and does not replace your sensor manufacturer's app. Never make treatment decisions based on Lumi alone — confirm with a fingerstick and follow your care plan. Questions? [email protected].
