Insert a test strip into the slot. NFC auto-identifies the strip type and the device confirms it's ready. Wash your hands with warm water to improve blood flow.
Use the included lancet on your fingertip. Apply a small drop (~1μL) to the test strip. Results appear on the LED display in 5–15 seconds and sync to the app.
Prick the side of your fingertip. It's less sensitive than the center.
