One App to Rule Them All!!!

These 3 points will make this app perfect and allow the Apple Watch to beat Fitbit in ALL areas. I'm speaking to developers.

1) Apple Watch Integration
• Allow for Apple Watch heart rate monitor and accelerometer and microphone if worn into bed. It can also assist with waking with the tapping in the wrist.

2) You guys have another app- Power Nap- that would be amazing to integrate
•Integrate it as a power nap mode. I take naps all the time. I am always calculating the time so I won't go into deep sleep.

3) Allow for both accelerometer and microphone to collect data.
• The accelerometer works better with the intelligent snooze but the microphone records more accurate data. Integrate the two for the ultimate experience.

4) allow editing to sleep data. When I lay in bed both before sleep and after waking it often records it as light sleep and sleep time is inaccurate which also effects sleep quality number.

Used to be great

This app used to be great back when it was free, when it based tracking off movement before audio.
But it started declining a while after it became paid. First, a one time payment. Then, subscription.

It’s all about collecting data and marketing in-app purchases now. And the tracking has no relation to real life experience at all.
With multiple smartwatch options, sleep cycle is now obsolete.

Tracks Everything

I love this app for how it tracks sleep

Banners

There is a “50% off Premium” undismissible banner at the top of the main tab. The app also keeps showing full-screen banners when I’m trying to go to sleep.

Great app for sleep

I bought the app a long time ago so I can’t attest to the subscription tier but as a heavy sleeper this one wakes me up every time during my lightest sleep. Thank you sleep cycle!!
