Does the iPhone app needs to be running through the night for this device to work? that's what I hated about Sleep Cycle and would not want to use it if it has the same flaw.
If you want the optimal wake feature to work you need to leave the app running. If you just want to collect data and wake up at a predetermined time you can background the app. Unfortunately this is a limitation imposed by iOS.
I can't answer for the original poster, but for me...
At night is when I charge my phone and there isn't always a plug near where I sleep.
Having my phone have to run at night without a charge will mean it's not fully charged at the beginning of the day, which is a very big deal breaker for me. My phone will last the entire day, but only if it's fully charged when I get up in the morning.
So with Wakemate, if it could run in the background with no need to be plugged in and screen shut down , relying on notification, that would be a great improvement.
As a person who pre-ordered the phone, that is appreciated very much:)
I wanted to chime in on this. I may not use my phone at night, but it is certainly receiving notifications and SMS messages throughout the night. This means that with any iPhone alarm, I have to go through numerous close dialogs just to get to my alarm in order to turn it off. A minor annoyance, but the wrist band helps. Otherwise, I'd have to go through my settings and disable notifications prior to going to sleep so as not to disturb me. <-- Heavy sleeper
Another flaw I would think is the potential risk of radiation of having it on you all night.
