Currently, we have only built a Karbon mobile app for iOS devices.
A Karbon Android app is in our plans, but we don’t have a definite timeline yet. First, we are focused on improving and testing our iOS app, before turning our attention to building an app for Android devices.
If you'd like us to release an Android app as a priority, please let us know by submitting a feature request in the Help & Feedback menu in your main menu of Karbon.
In the meantime, you can also view Karbon in the browser of your Android phone or tablet.
