Yes. Version 4.1 added support for airplay, bluetooth and external speakers.
Using airplay: Double-tap the home button. Swipe to the right until you reach the iOS volume settings. Press Airplay and choose your speakers.
Using external speakers with cable or dock: Just connect the cable to the headphone input, or dock your phone.
We recommend disconnecting your headset when running an alarm.
The alarm will sound though the headset in the morning (but the vibration will wake you up anyway).
We made this change in version 4.1 to ensure people with reduced hearing can connect external speakers with a cable, dock or Airplay.
The Sleep Quality is affected by two factors:
* Total time asleep
* Amount of movement
In short, the more you sleep and the less you move, the higher Sleep Quality.
Sleep Quality will be calibrated the first nights using Sleep Cycle, and the value will be more and more accurate over time.
We are currently researching the next version of Sleep Quality, with factors such as waking up in the middle of night, % deep sleep, number of sleep cycles etc. affect the value.
Yes. You can exit Sleep Cycle 4.0 after you have activated your alarm, and you will see a red bar in the top of the iOS menu. Background mode is fully supported from iOS 5.0 or higher.
Yes. Just make sure to lock your phone after setting the alarm, since DND only works when the phone is locked.
Yes. Under the tab Settings, at the top of the screen, just change Alarm to Off. Sleep Cycle will now only analyze your sleep and not wake you up.
Under the tab Settings, go to Sleep notes or Wake up mood and change the settings to On. From there you can also change the default Sleep Notes by choosing “Edit sleep notes”. Sleep cycle will now each night ask you to input your sleep notes, when starting the alarm before going to sleep. And you will be asked to enter your Wake up mood in the morning when you wake up.
The volume in version 4.1 is totally independent of the iOS volume. Sleep Cycle will sound even if your iPhone is muted, you have turned off the volume, or you are using Do not disturb in iOS6.
The volume under Sleep Cycle settings will define the starting volume of the alarm. After about 1,5 minutes this is increased automatically until maximum volume is reached.
Yes. We support all iPod Touch devices except the first and second generation iPod Touch. We also support all generations of iPad.
We do not recommend using Sleep Cycle without a charger connected. Sleep Cycle uses at average 30% of the battery during one night. Sometimes more sometimes less. If you do not charge your iPhone/iPod touch during the night it can become discharged. Then the alarm will not sound in the morning. If you still want to try Sleep Cycle without a charger we recommend using a regular alarm clock as back up.
No, this is not normal. Make sure you do not cover your device with anything more than the sheet. For example, make sure that your pillow does not cover your iPhone/iPod touch.
We cannot guarantee that Sleep Cycle will work on these mattresses. Even so, a lot of users have used Sleep Cycle on such mattresses and said that it works well for them.
Yes. The alarm will sound in the morning even if the device is muted.
There is no need to reset the alarm during the night.
We have done a lot of testing in order to make Sleep Cycle work with two persons in bed. The short answer is: yes, Sleep Cycle works very well with two persons in bed. It could be a problem if the person using Sleep Cycle weighs much less than the other person but in normal circumstances it works very well.
There are two cases regarding this issue:
1) Sleep Cycle has a hard time detecting your movement.
In this case the movement of the other person will not be registered at all so there really is no issue. Sleep Cycle will work in a mode that uses all movement detected for the sleep analysis.
2) Sleep Cycle detects a lot of movement, from you AND the other person.
In this case Sleep Cycle will adjust it’s algorithm to only register larger movements. The small movements will be filtered. Since the other person is further away from the device these movements are smaller and will be filtered out.
Our extensive testing show that this works well.
Sleep Cycle detected movement and created a graph when I placed it on a table during the night. Why?
Sleep Cycle needs one, sometimes two, nights to calibrate to your accelerometer. Usually the calibration is not needed but on some (very few) devices the accelerometer is too sensitive and can detect movement when there was none during the first one or two nights. If you place your iPhone/iPod in bed, according to the instructions, then this is not a problem.
When calibrated, Sleep Cycle is extremely sensitive to movement. It can detect the slightest vibrations. For example, you walking past the iPhone/iPad or a car/truck passing by on the street outside.
When you place your iPhone/iPad on a flat surface then Sleep Cycle detects very little movement. It then assumes that the users movements are very difficult to detect and goes into a mode where every movement is treated very seriously (and creates a big spike in the graph).
If you still feel Sleep Cycle creates inaccurate graphs, please do not hesitate to contact us. We’ll analyze your data and check if you have discovered an issue with the Sleep Cycle movement-detecting code.
Sleep Cycle needs at least two nights to adapt and calibrate to your accelerometer. Taking that into account it is possible for the alarm to go off at the end of the time 3-4 nights in a row when you start using Sleep Cycle.
You can also have a look at the sleep graph examples to see if your phone is sensing your movement correctly.
