iPhone: The stock music player for the iPhone is fine, but it requires you to keep your eyes on it to use it. In:play is a music player designed so that you can use it without ever looking at the screen.
The basics of in:play are simple: you navigate the menus with gestures or taps. For instance, a right swipe on a track or album starts playing it automatically. Once you're playing a song, you can tap anywhere on the screen to pause it, or swipe anywhere to change the track.
Essentially, you never have to look at the screen to navigate through it. On top of the basic navigation, in:play has lots of other little tricks hidden inside it. For example, you can double-tap on a currently playing album and quickly navigate through other albums from the same artist. You can always load up your library instantly by swiping down on the screen from pretty much any menu.
Additionally, in:play supports AirPlay and a night mode. If you're looking for a music player that doesn't require you to peck through menus, in:play is worth a look.
