NoMeat Hybrid App
The app fuctionality in comparison to the earlier version is basically the same. Users see a calendar and click on days that they want to track as “no meat-days”. Of course, they can track whatever they want.
One advantage that comes with installed apps from the app store is that apps can use the local device storage to store data. So users don’t need internet connection to use the app. You also don’t need a user account unless you want to use the app on different devices.
