Tactus is an iOS app I developed for a few reasons. 1) Apple's music player keeps getting worse, and 2) I wanted something that was easier to use when hitting/hunting small buttons wasn't necessarily in my best interest. #1 I think was kinda true for v1, but it has improved a lot for v2. #2, being probably the main driver for the project, I feel is very successful.
One of the main problems though has been testing. TestFlight didn't exist before, so I am hoping to get a lot of input, especially in the following areas:
This YouTube video of the previous version of Tactus should be a decent intro to what the app is about. Same gestures, but different functionality in a lot of cases.
The following images describe some detail in to gestures and how they work or why decisions were made a certain way.
