Sleep Tracking Ai

Do I need to sleep with my phone?

No, but we recommend wearing your Watch or Fitbit for better accuracy

You don't need to keep the phone on your bed or pillow, as long as you handle it right before sleeping and soon after you wake up, so it registers the motion. Most people do this, so it ends up working well.

If you leave your phone on your desk or charging for many hours before and after you go to sleep, then your sleep may be inaccurate as we won't have any information to use.

Do I need RescueTime?

We don’t strictly require it, but the sleep estimation may not be correct without it.

Without that data, you may get false positives if there is no motion data in the evening — ie. if you're sitting at your desk and working.

What if I already have a tracker?

If you already have sleep tracked in Gyroscope — through a sleep tracker or manually entered in HealthKit — then we will use that instead of trying to calculate it for the day.

Then we can just fill in the gaps for days where you didn't have any sleep — for example if you forgot to track it or if you were traveling. Sleep tracked with a hardware sleep tracker will often be more accurate than our measurements, which are rounded to the nearest hour or 15-minutes.

Can I use it without an iPhone?

Yes, but you do need a detailed source of steps for us to have enough motion data. We can do it through a Fitbit or Jawbone device, or through an Android Wear device connected through Google Fit.

You can also see all of your sleep data on the website, in the reports section and in the Helix theme.

Does it support time zones?

We have complete time zone support for storing data, but the reports will show in your current time zone.

If you travel a lot across timezones, the sleep may not be as accurate and the bedtime and wake time may be skewed due to time differences. However, the sleep duration report should still be accurate. This is something we are constantly improving and recalculating as we learn more.
