Sleeptracker-24/7 FAQ

I put my iPhone on the floor or a table while recording sleep and see sleep data, why is this?

Placing your iPhone on a solid surface such as the floor or a table while recording sleep causes MotionX to become highly sensitive to very small movements. This level of sensitivity is required for users sleeping on a very firm or motion-absorbing mattress (such as Tempur-Pedic®).

However, with the iPhone on the floor or table, noise from the accelerometer sensor can be registered as sleep cycles resulting in a random sleep graph and random sleep statistics.

Ensure that you place your iPhone according to the instructions, either in bed or in an armband, so that 24/7 can accurately monitor your sleep and wake you up at the optimal time.
