What's New in Version 2.2

This is a notable update! Here's what's new:

• Discover your "Sleeping Heart Rate Dip", an estimate of how much your heart rate slows—or "dips"—while you sleep compared to waking. The amount heart rate slows during sleep has been found among particular populations to be an important indicator of overall and cardiovascular health. Get motivated to build a healthier lifestyle by seeing how adopting small lifestyle changes — like a healthier diet and more physical activity — impact your estimated Sleeping Heart Rate Dip.
• Now you can track changes in your Total Restful Sleep Time and Sleeping Heart Rate Dip estimates on a daily, weekly, or monthly basis in the Trends tab.
• Now you can drill into the details of your sleep activity and heart rate data by tapping on the 'Avg. Sleeping Heart Rate' or 'Sleep Activity' widget from the Today view for a moment-by-moment analysis. On that detail view, press-hold-and-drag to display a helpful timestamp indicator. On the Today view you can now scroll up or down to reveal the 'Avg. Sleeping Heart Rate' widget.
• If your Sleep Watch regularly and significantly over-estimates or under-estimates your Total Sleep Time, you can now change your "Sleep Detection Sensitivity Level" to either "Low" or "High" from the Account menu.

Customer Reviews


I haven't used my Apple Watch in months. Part of the reason being that I want to use it to track my sleep and there was no convenient way to do so. Most sleep apps require you to launch them on the phone and watch then set them to sleep mode. This would be okay if I weren't a borderline insomniac - the very act of going through all this when I was so close to sleeping was enough to keep me up for a couple more hours. So this little app has been a godsend. Not only has it accurately detected when I fell asleep without all the "sleep-mode" business, it has even done so with me falling asleep and waking up at weird times like my little 5am-10:00am incident the other day. Keep up the great work as I will definitely recommend this to others. Also, extra kudos for not requiring an account.

Constant Improvement

The reason I got this app was because of the activity in the updates. They are really working hard to make this app the best it can be. I have total confidence that this will be everything I want. The addition of the sleep graph was nice. It shows that it knew when I woke up because the sleep time didn't display that. It's a little hit and miss with my sleep times but not too far off. Perhaps a monthly trend of sleep? I think a graph of the sleeping heart rate would be a great idea. I'm looking forward to what's coming next.

Update: This app just keeps striving to be the best. The new sleep heart rate dip feature is a nice new metric. I got my graph of the heart rate I asked for. Love this app.

Terrible Customer Service

I bought this app about 2 weeks ago. I really wanted an automatic sleep tracker. I work overnight and I wanted to track my naps during the day, I have 2 kids I can't just come home and sleep 6-8 hours, so I break my sleep up and wanted to track that to make sure I was hitting my goal. Well after 1130am this thing does not track. I didn't see anything in the description of it only tracking until a certain time. I can get a free app to track manually and did not need to pay for something not to work. I reached out to app support-- what support?? No answer, no automated we will get back to you, not a peep...I wish I could give it zero stars for their lack of responding. So 3rd shift workers beware, this app will not help...
