Glucomate is your iOS companion app for recording, tracking, and monitoring blood glucose. From Zach Simone’s release announcement:
It’s an app for people who record, track, and monitor their blood glucose and use HealthKit to do it. Glucomate is the app that finally does something with all that data. You can analyse recent readings, spot trends, or go back to any date and view its history. It does all this while trying to look as good as possible. A notable feature is the ability to customise each of the tabs by reordering the displayed data. You can even choose to hide the data that isn’t relevant to you.
