15-Day Wear

No Daily Calibrations

Set it once and let the data flow.

Why Harmony

A clearer picture of how your body responds — every day.

Most of us run on rough guesses about energy, sleep, and how meals land. Harmony quietly fills in those gaps so the day-to-day choices add up.

Real-time glucose trends

Watch your readings move smoothly through the day. Spot which meals, walks, or evenings shift your curve — without spreadsheets.

Gentle alerts

Configurable nudges when you're heading outside your comfortable range — quiet enough to ignore at work, clear enough to act on.

Weekly snapshots

Friendly summaries with what trended up, what trended down, and one small thing worth trying next week.

Tidy on the arm

Sensor weighs less than a sugar cube. Sits flat under sleeves, stays put through showers and workouts.

Two-week wear

One sensor lasts a full 15 days. Pull off the backing, press it on, forget about it.

Quietly shareable

If you'd like, a partner or family member can follow along — encouraging, not intrusive.

How It Works

Three small steps, then it's automatic.

No appointments, no syringes, no daily setup ritual. Open the box, attach the sensor, and the app does the rest.

Unbox & pair

Open the Harmony app, tap "Add device," and bring your phone close to the sensor pack. Pairing takes about 20 seconds.

Attach to your upper arm

Use the included applicator on the back of your arm. A quick press, no setup ritual, no daily fuss.

Let the data flow

Within an hour you'll see your first glucose readings. From then on, the app keeps your trend line current — for 15 days straight.

From Our Customers

Quiet days, clearer evenings.

A handful of stories from people who built Harmony into a regular weekly habit.

★★★★★

"It's the first wellness gadget I haven't forgotten about by week two. The app shows my afternoon dip clearly and now I bring an apple to my 3 PM call instead of coffee #4."

Rachel D. — Portland, OR
★★★★★

"Painless application, lasted the full 15 days through two showers a day and a 5K. I appreciate that the alerts are quiet — no shouting, just a gentle vibration when something's off."

Brian K. — Austin, TX
★★★★★

"My partner and I both wear it during the same two weeks now. It's become a quiet conversation starter at dinner — 'how did your morning trend?' Strangely fun."
