Battle Snake (iPhone, iPad) Free (was $0.99)

Chances are, you’ve played Snake before: it’s a game in which you steer a snake around a grid, trying to get as long as possible without your head running into your body as it grows longer and longer.

Battle Snake takes the premise a step further with a multiplayer mode. Your goal isn’t just to drive your way around the grid without accidentally killing yourself, but rather to try and sabotage your opponents while gathering score blocks and power-ups for yourself. It’s free for the next few days, so grab this one while you can.

Front Camera Flash (iPhone) $0.99 (was $1.99)

This iPhone 4 app has a single job: it uses the phone’s display as a flash, so you can take photos with the front camera in various lighting conditions, not just full daylight. You can also set a delay before the photo is taken, so you have a chance to get ready.

Snag this app for half-off today, and start taking clearer, higher-quality front camera photos.

RelativePitch (iPhone) $3.99 (was $7.99)

Wish you could really understand the music you’re listening to? RelativePitch can help — it’s a music education app that trains you to listen to different sounds and understand how they work together.

RelativePitch uses various musical exercises, quizzing you to identify tones and tell how sounds are the same or different. You can also customize your learning experience and use different modes, including a training mode to help walk you through how the app works, and a testing mode to gauge how you’re progressing.
