Sleep Watch

Smartly de­signed app for track­ing sleep

$2.99 From Body­mat­ter, sleep­ Made For iPhone, Watch Needs iOS 9.0 or later Ap­ple clearly has sleep track­ing on its radar af­ter ac­quir­ing Bed­dit ear­lier this year, but if you want to mon­i­tor what’s go­ing on while you slum­ber, there’s al­ready an app for that. With one caveat: You’ll need to keep Ap­ple Watch strapped to your wrist while you’re in bed.

Sleep Watch uses ar­ti­fi­cial in­tel­li­gence and ma­chine learn­ing to pro­vide in­sight into your noc­tur­nal habits, in­clud­ing sleep rhythm track­ing to help you get back to a reg­u­lar sched­ule. Most of the heavy lift­ing takes place on iPhone, so Ap­ple Watch be­comes a pas­sive par­tic­i­pant used as a tool to col­lect data while you sleep.

The iPhone app looks great and pro­vides a wealth of au­to­mat­i­cally recorded data – there’s no way to ini­ti­ate track­ing by hand – but you can man­u­ally con­firm sleep times when you for­get to wear your Watch. You can also en­able a fea­ture that in­quires how rested you feel each morn­ing, which will be in­cluded with other logged data.

The watchOS app isn’t ex­actly a slouch, and does a good job of dis­play­ing recorded in­for­ma­tion, in­clud­ing rest­ful sleep, av­er­age heart rate, and, more im­por­tantly, how much your heart rate dipped while you were snooz­ing. Some of this data can even be dis­played on your pre­ferred Watch face, thanks to the app’s sup­port for com­pli­ca­tions.

There’s just one big prob­lem: Many Ap­ple Watch own­ers have a hard time just get­ting through the day on a sin­gle charge. If you have to wear it all night to use Sleep Watch, when will you have time to recharge the bat­tery? This isn’t re­ally the de­vel­oper’s fault, but it’s likely to be an is­sue for many users.
