Entry screen: a reading of 186 mg/dL with the context suggested before dinner Today screen: every reading on a 24-hour dial, in range at a glance Report screen: a PDF report ready for the doctor Meter scan: the camera reads the number from the meter screen

No gimmicks

Glyka does not measure blood sugar with your camera or your face. No app can.

Glyka records the number from your meter, and can read it off the meter's screen with the camera so you don't have to type. No blurred charts, no fake “preparing your profile” screen.
