Good Spirits is a drink tracker for iOS. Ever since learning about the correlation between drinking and various kinds of cancer, I've been meticulous about logging and tracking every drink I consume. Good Spirits makes this process easy: just set a weekly limit, check in your drinks, and the app will let you know when you're in the danger zone. For the craft beer drinkers, you can automatically pull new check-ins from Untappd. Free and soon-to-be open source!
I built two macOS apps that turn your desktop wallpaper into a rotating mini-art-gallery. (Art not included, though!)
MusicMessages! is a collaborative step sequencer for the iMessage App Store (iPhone, iPad). Using the simple and (hopefully) intuitive interface, you can punch in a few chords or a percussion line and send the message off to your friends, who can then make their own changes and send it back. Five instrument layers and over 40 MIDI instruments are available to use. Bonus: if you have an iPhone 7, the note buttons respond to pressure and "pop" like bubble wrap with the help of the Taptic engine!
