What's the difference between Sleep101 and Zeo?
Sleep101 is a free smartphone app that uses your movements throughout the night to track your sleep. Zeo is a $99 scientifically validated smartphone accessory that uses your actual brainwaves to track the different phases of sleep you progress through every night. Zeo is the most accurate way to track your actual sleep phases, but the simpler Sleep101 is enough to help you start to understand your sleep and take control of it. For more information, compare Sleep101 to other sleep tracking technologies.
How does Sleep101 wake me up feeling more refreshed? What is the Smart Alarm/SmartWake?
When you turn ON the Smart Alarm/SmartWake setting in Sleep101, the app will wake you up at an optimal time during the 20 minute window before your set alarm time. The app uses your movement to guess when you are less likely to be in the deeper part of a sleep cycle, so you can wake up feeling less groggy and more refreshed. Note: You will never be woken later than your set alarm time.
How accurate is Sleep101?
Sleep101 is 86.2% as accurate as expensive wrist-based sleep monitors (tracking your sleep based on wrist movements), a clinically proven way to track your sleep.
Where did 86.2% come from?
Sleep101 accuracy is based on an internal validation study by Zeo; using a prospective analysis, we compared the results of Sleep101 to wrist actigraphy for each 30-second epoch across multiple subjects over several nights.
How long does each bar last on the sleep graph?
Each bar on the sleep graph is a 5 minute block of time.
What are the different phases on the sleep graph?
For each 5-minute period, Sleep101 decides whether you were:
- Likely Awake- Sleep101 detected movement that lasted more then 30 seconds.
- Disrupted- Sleep101 detected movement that lasted less than 30seconds.
- Asleep/Resting- Sleep101 did not detect any movement for 5 minutes.
Do I have to keep the app running at night?
Yes, in order for Sleep101 to track your sleep, it must be open and running throughout the night.
Will the alarm ring if my phone is locked?
No, your phone needs to be unlocked for the alarm to ring.
Do you support iPod Touch?
Yes, Sleep101 works just as well on an iPod Touch.
Do I have to keep my phone plugged in all night?
Yes. Keep your phone plugged in to prevent it from running out of battery at night.
How well does Sleep101 work if I sleep with a partner?
Sleep101 was designed for single-person use, though will still give you a good idea of how well you slept even if you have a bed partner.
How well does Sleep101 work on memory-foam style mattresses?
In BETA: we're still working on tweaking this feature, but it's good enough to try. For all memory-foam mattress users, turn "High Sensitivity: ON" in the settings (and let us know if it works better).
Do you have an app for Android?
We currently don't have a version of Sleep101 for Android, but we do support the app called ElectricSleep.
What should I do now that I have this sleep data?
Sleep data is most useful to help you understand:
- How you're actually sleeping AND
- What impact different lifestyle changes have on your sleep quality.
