Google Fit and
Apple HealthKit. If the app is installed on Android it need to read from Google Fit. If the app is installed on iOS, it need to read from Apple HealthKit.
I found an article how to read from Apple Health Kit using Ionic framework. But I don’t any references how to read from Google Fit using IONIC.
Is there any hybrid app frameworks implementation examples that can read fitness history from both Google Fit and Apple Health Kit?
