Used Data Sources

Nightscout Project
Checkmate is using the Nightscout glucose data API to receive your raw glucose data and calculate and visualize the up- and downs of your current diabetic treatment status. Therefore a Nightscout database is mandatory to run Checkmate. Follow the guide here to set-up a Nightscout database

XDrip (with for example the Dexcom G6) can be used to upload glucose data from the smartphone to the Nightscout cloud. This program is not replacing any functionality of XDrip+ which can be downloaded at Jamorham’s Page.


I want to thank A.S. for his great contributions and improvements of the features and checkmate code. The Nightscout project, Jamorham, and PhilJay from MPAndroid for making this project possible and for improving my life as a diabetic to a degree which would be not possible with the commercialy available software.
