If you’ve ever wanted to prove just how loudly your significant other snores or that they really do steal your covers, then you guessed it – there’s an app for that. SleepKeeper is a simultaneously creepy and fascinating app that tells your iPhone or iPad to take incremental photos and sound recordings while running. Designed to be used during sleep, SleepKeeper compiles the photos taken into a brief “sleep theater” time-lapse video that lets you see what you or others do while sleeping.
On the one hand, SleepKeeper acts as a quasi amateur sleep study. The increments for photo taking can be set to 5, 7, 10, 15 or 30 minutes and the duration of the incremental sound recordings can be set to 5, 10 or 15 seconds. For fun, SleepKeeper throws in a “graph lab” that organizes sleep sessions into a timeline and “records” the stages of sleep. Being realistic about sleep studies, the graph lab obviously isn’t capable of actually measuring stages of sleep, but it does give you the opportunity to view photos taken at or around a specific point on the time line. There may be no way for SleepKeeper to actually show you when you or your subject reaches REM, but it could be interesting to see what you look like at 1:00 a.m. versus 5:00 a.m. (more...)
