The Accu-Chek SugarView app determines the blood glucose range using the Accu-Chek Active test strip and two photos taken off the strip with a smartphone camera. An easy-to-follow, step-by-step guide leads the user through the testing process. A dedicated algorithm assigns the blood glucose result on the test strip to one of the categories ranging from "low" to "very high". Based on the testing result, it combines the blood glucose range with basic information on how to take action, such as exercise or eating. The app is an approved invitro diagnostic medical device with a CE mark (CE0123).
