Will you support iOS8 and the Apple Health App?
Yes, sleep cycle will have full support for Apple Health.
Will you support Apple Watch?
Why is it asking me for permission to use the microphone when I start an alarm?
The app uses the microphone for noise analysis and some background support. It does not record and store anything.
It does not matter if you give permission or not, the app will work perfectly anyway since the accelerometer is the primary source for analysis.
Does Sleep Cycle function in the background / background mode?
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.
Does Sleep Cycle work with Do Not Disturb in iOS?
Yes. Just make sure to lock your phone after setting the alarm, since DND only works when the phone is locked.
Important: Your incoming messages will always be muted when Sleep Cycle is used in the background and without Airplay set to On. Keep Sleep Cycle in the foreground without locking the phone and activate Airplay in Settings/Advanced if you want your incoming messages to sound.
Can I run Sleep Cycle in “No alarm mode”?
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.
How is Sleep Quality calculated?
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.
Why are my notifications silent?
Activate AirPlay support under Settings/Advanced and keep Sleep Cycle in the foreground without locking the phone. Sleep Cycle will still function normally and the alarm will sound through your phone, (unless you actually connect AirPlay speakers).
Can I activate Airplane mode via the app?
No. It is not possible for us to automatically set airplane mode when going to bed, this is an limitation Apple has set on us developers.
Do I have to keep the charger connected all night?
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.
Does Sleep Cycle function properly with auto-lock on?
Yes it does.
How well does Sleep Cycle work with 2 people sharing a bed?
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 its 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.
Does Sleep Cycle work on water beds or memory foam mattresses, such as Tempur?
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.
If I wake up in the middle of the night and get up from the bed, should I reset the alarm?
There is no need to reset the alarm during the night.
The alarm always goes off at the end of the time! Why?
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.
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.
My iPhone/iPod touch becomes hot during the night. Is this normal?
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.
How does the volume setting function in Sleep Cycle?
The volume in 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.
Can I listen to music or podcasts while using Sleep Cycle?
1. Set an alarm.
2. Start your music.
Can I use my own MP3 music as a wake up melody?
Can my iPhone/iPod touch be muted (work in silent mode)?
Yes. The alarm will sound in the morning even if the device is muted.
How will Sleep Cycle work with headsets connected?
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.
Do you support external speakers using Airplay, Bluetooth, dock or cable?
iOS7: Yes, activate support for Airplay under Settings / Advanced / Airplay.
iOS6: Yes, airplay, bluetooth and external speakers are supported.
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.
What does Activity and Steps mean?
If you have a iPhone 5S the phone measures your activity during the day automatically. Activity is the amount of steps you have taken since your last sleep session.
You do not have to keep the app running to measure steps, the phone does this automatically. If you do not want the phone to measure this please go to:
iOS Settings -> Privacy -> Motion Activity
How do I enable Sleep notes or Wake up mood?
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.
What is SleepSecure?
SleepSecure let’s you sync your sleep cycle data seamlessly to the cloud and between devices. With SleepSecure you can change, restore or upgrade your device without having to worry about losing your data sleep cycle data.
In addition, you also get access to SleepSecures web interface where you can look at bigger graphs, export your data, see quick stats and more.
Some of the graphs currently available in addition to the standard ones found in the app are:
- Went to bed per day of the week
- Time in bed per day of the week
- Time in bed vs Went to bed
- Sleep note usage
More graphs and feature will be added continually
Does Runkeeper work with Airplane mode activated?
No. Runkeeper integration works only if Sleep Cycle is used without Airplane mode.
Do you support iPod Touch or iPad?
Yes. We support all iPod Touch devices except the first and second generation iPod Touch. We also support all generations of iPad.
Does Sleep Cycle works with Exchange server auto-lock security features on?
Yes it does.
