The app, which arrived on the App Store in December, monitors the volume and frequency of your breathing to figure out whether you're snoring. "The noise has to be strong enough and continue for a second and then repeat" for Snoring U to leap into action, Pointer CEO Ilan Aisic explained to me on the Expo show floor.

When Snoring U determines that you're sawing logs, it can vibrate or play a sound clip of your choosing; the idea is this will nudge you into rolling onto your side. You can set how many times the app will sound off each night as well adjust its sensitivity to snoring.

The app works after the screen auto-locks and the iPhone goes into sleep mode. Aisic estimates that over the course of an eight-hour night, the app will consume about 20 percent of your battery power--assuming that you don't keep your phone plugged in on your nightstand.

Currently at version 1.1, an update to Snoring U is in the works that will add a history feature to the app which will log how often and how loud you snored as well as how many times Snoring U had to vibrate or play a noise.
