Programmed and designed by Peter Mostoff. You can contact me via Twitter if that's something you're interested in. I typically make things for the situations that they're needed in but I like to share my work and I'm sure there are plenty of ways that this can be improved. Please let me know if you have any cool suggestions!

If you're interested, you can visit my personal site to see what I'm up to at Mostoff.me or if you want to support my work, check out the apps that I've published on the App Store!
