SugarData
Open app

A display. A bridge. Your data.

Your glucose.
In plain sight.

A dedicated screen for a quick glance. A bridge to bring your sensor readings online. SugarData connects them in one simple place.

01 / The display

A little screen.
A clearer view.

Keep glucose visible on your desk or bedside table. See the reading, where it’s heading, and how recently it arrived.

The essentials, together

Large glucose numbers, a trend indicator, reading age, and recent history. Choose mg/dL or mmol/L.

Your choice of source

Use your own or a shared SugarData bridge, connect an existing Nightscout feed, or read a G7 sensor directly on a supported ESP32-S3 display.

Set it up from the app

Adjust brightness, units, and display settings. Check device status and install firmware updates from SugarData.

02 / The bridge

From your sensor.
To your screens.

A SugarData Bridge reads a G7 sensor over Bluetooth and uploads readings over WiFi. Use a dedicated T-Beam, or let a supported display do both jobs.

Two ways to connect

Keep a dedicated bridge near your sensor. Your other displays receive its readings through SugarData.

History with context

Review a seven-day chart in the app, along with sensor status and battery information where supported. Devices can backfill up to six hours of readings.

Share on your terms

Give someone a viewer role to see readings, or a manager role to help with settings. Both displays and bridges use the same permissions.

One device can do both

A supported ESP32-S3 display can show your readings and bridge them to SugarData. No separate collector is needed for that setup.
