Every currently available client that I tried to use was either too simple (single-feature), required payment for the most basic of features (such as commenting on an issue) and/or didn't have the best UI. For all of these reasons, I built GitPoint.
I launched the iOS version of the app two weeks ago and we've already picked up a decent number of users (~3000). With some amazing contributors, we've added a number of new features since then as well as publish the Android version just yesterday!
Please don't hesitate to leave feedback of any kind!
If yiu could add starred repos to the profile view( maybe in a 2x2 grid instead of 3x1), it would be perfect.
Starred repos serve as kind of a code bookmark /read it later service for me and sometimes I like to browse through it before starting a new project to get ideas.
