According to the American Sleep Apnea Foundation, sleep apnea affects over 12 million Americans, but “the vast majority go undiagnosed.” If you find yourself suffering from daytime sleepiness and loud snoring at night, you might have sleep apnea.

The Sleep Aid App will record you sleeping, then allow you to compare your snoring and nighttime activity with samples of sleep apnea. This way, you can test yourself and be alerted to this life-threatening disorder without the need to go in for an expensive sleep study.
