Apps
In general, all of my apps are free and open-source, with the code available on GitHub.
Note that my Android apps are no longer maintained. They were designed for older versions of Android and may or may not work on newer versions. Since Android itself does not typically maintain compatibility with older apps, they may or may not appear in the Play Store, but you can download the APKs below.

Relatedness Calculator
Ever wondered how you’re related to your second cousin? How about your great half-uncle? And what in the world is a “double cousin,” anyway? The Relatedness Calculator can answer all these questions and more, drawing a nice little graph and calculating the relatedness coefficient for many different kinds of relations.
Imperial Calculator
End-of-game score calculator for the board game Imperial. It was basically just a “Hello World” app to teach myself AngularJS, Bootstrap, and PhoneGap, but you might find it useful if you like the ingenious board game by Mac Gerdts.
Japanese Name Converter
Transliterates English names into Japanese characters – both katakana and roomaji. Uses the machine learning method described in this post.
Ultimate Crossword (defunct)
Inspired by an XKCD comic, it’s a crossword-solving app based on a leaked database of password hints. It makes an important statement about password security (I hope), and plus, it’s fun to try to “solve”!
Update: I have retired the Ultimate Crossword. It was an interesting experiment, but it’s time to let it go. The code is still available.
Pinafore
Pinafore is a web client for Mastodon, focused on speed and simplicity. It’s the project I’m mostly working on these days.

Android apps
CatLog
I was disappointed with the other Logcat applications on the Market, so I wrote this one. It’s basically everything you’d ever want in a Logcat app. Record logs in the background? Check. Save, open, and send logs? Check. Home screen widget? Check. If you needed a kitchen sink to read logs, I would have added that, too.
Developers: You can invoke CatLog from an external Intent. Learn how.
Chord Reader
A straightforward app that allows you to download chord charts from the Interwebs and transpose them. I wrote it because I was tired of having to manually transpose all my chord charts in order to accommodate my pathetically tiny vocal range. It also shows guitar fingerings for each chord.
KeepScore
KeepScore is a score-keeping app that can be useful for any game requiring you to tally points as you play, such as hearts, Carcassonne, Scrabble, etc. I wrote it because I like to play cribbage, but I found all the other score-keeping apps on the Android Market to be too clumsy and awkward.
For older Android devices (< 2.1 Eclair), please download the legacy 1.1.4 version of the APK.
Pokédroid (defunct)
The perfect app for either the Pokémaniac who’s gotta catch ‘em all or the Gen-Y hipster trying to be ironic. It started out as something of a joke app, since the main feature was that it used the Android TTS engine to speak aloud each Pokémon’s description, similar to the Pokédex in the TV show. Now it’s more of a full-on strategy guide, with lots of detailed info for Pokémon gamers. Supports generations three through five.
Update: In June of 2011, Pokédroid was removed from the Google Play Store due to a DMCA takedown notice from The Pokémon Company (TPC). The app will stay down.
