iOS App - HiLo Interval
Aug 2013 Geoff Davis
I'm responsible (or to blame) for everything about this app. I built it from scratch in native Objective-C / Cocoa Touch, backed by a Core Data database. It features optional randomization of the intervals, and allows users to play alternating iTunes playlists, depending on the interval. Playback was complex enough that I ended up making a Finite State Machine to handle it.
Not only that, but all design and artwork are mine, lovingly hand-crafted in Illustrator and Photoshop, pixel-perfect for both Retina and non-Retina display. No blurry lines or weird anti-aliasing here. I even bought the faux-LED font off some Russian dude for $25. Isn't the Internet great?
As of this writing, my app has grossed around $58 USD worldwide. My strongest markets are the U.S., U.K. and Australia, which probably says more about the app's current lack of localization than anything else. (I'm counting on Canada to come on strong.) I didn't do much to promote it, as I have much more grandiose plans for my second app...
