Tabletime isn't available on the App Store - but you can still use the app on iOS!
The iOS version includes all the features that the native version has, except for notifications.
Installing Tabletime on iOS
To use Tabletime on iOS follow these instructions:
Tap here to open the web version of the app in Safari
Tap the share button
Scroll down and tap 'Add to Home Screen'
Now Tabletime should appear on your home screen just like any other app!
Why isn't Tabletime on the App Store
The reason Tabletime isn't on the App Store is that Apple charges developers an annual fee
of $99 to be able to publish apps.
As I am a small developer and this app is not monetized with ads or in-app purchases, I do not have the funds to
publish on the App Store.
