GitHub is probably the largest code hosting service in existence today, but its mobile presence is … lacking. The company released an Android app back in 2012, but it was removed from the Play Store in 2015. GitHub has announced a new brand so far, but there is no clear launch date for Android.
The new mobile app, which is already in beta for iOS, is dedicated to providing features that a developer might want. That probably means no code editing, but you'll be able to share comments in discussions, integrate code changes, view files, go through notifications, and more.
GitHub has not explained when the Android version will be available, just that it will be available soon. Good things come to those who wait, don't they?
