★★★★★ Not sure what your expectations are, but since the Apple sleep feature is more robust, I guess it doesn't matter, so it's a useless app
★★★★★ It's been inaccurate and can't deal thinking I'm not well.
★★★★★ Just a place to manually journal that you've slept. Compared to Sleep As Android, this is truly an embarrassment
51 of the 1 and 2 star reviews.
★★★★★ Won't read “active energy” no matter how many times you toggle it off/on in the apple health app
★★★★★ This used to reliably work but stopped accurately tracking my sleeps and cuts off half the night constantly. The FREE Health app Apple offers does this better than this guy's development does. How did this app get…
★★★★★ It does not work automatically and has to be started and stopped.
25 of the 1 and 2 star reviews.
★★★★★ App has been great for years, tolerated ads and now you want to paywall my sleep history in the app???
★★★★★ They will keep your credit card info and charge.
★★★★★ It is off by hours even though watch is fully charged and securely on my wrist.
23 of the 1 and 2 star reviews.

★★★★★ I have emailed the dev and messaged him on Mastodon with no response.
★★★★★ I have received no response from you and the app seems to be sitting dormant.

★★★★★ App has been great for years, tolerated ads and now you want to paywall my sleep history in the app???
★★★★★ Seems kinda goofy that I can't access my history anymore. I've got years of data on this app and now I can't even view it all :/
★★★★★ It's a great app for tracking sleep but the ads are awful.

★★★★★ This app no longer works and freezes with my Apple Watch four.
★★★★★ For whatever reason, stopped recording last April… and App is freezing while trying to dig in… Not going to look further, others App are working fine and improving.

★★★★★ Yo, i wanted to say thank you to the developer for making such a simple yet useful app for free when others are horrific in comparison.
★★★★★ Easy to use app that does it all.
★★★★★ You are a great intuitive developer, ignore some of the negative comments.
19 of the 4 and 5 star reviews.
★★★★★ Love the app—would be cool if (1) it reported your sleep deficiency to calibrate where you're at, (2) would love to see Core, Deep, and REM graphed over time to see if there's trends impacting sleep quality over time,…
★★★★★ Accurate to the minute on times awake during sleep.
★★★★★ Even the basic info is accurate for me and nice to have, but I really prefer having more advanced than analysis regarding my sleep stages.
15 of the 4 and 5 star reviews.
★★★★★ It helps guide you on possible approaches you have to your sleep cycle.
★★★★★ Yo, i wanted to say thank you to the developer for making such a simple yet useful app for free when others are horrific in comparison.
★★★★★ The “Trim Night” feature is very useful to remove false sleep data recorded while I am reading books.

★★★★★ Yo, i wanted to say thank you to the developer for making such a simple yet useful app for free when others are horrific in comparison.
★★★★★ Has the same (some even better) features as most other apps that cost a subscription. Highly recommend
★★★★★ It's great that it's currently free and I'm going to pay for the app.
7 of the 4 and 5 star reviews.
★★★★★ I really enjoy using this app.
★★★★★ I've enjoyed Pedometer++ for years, but only recently added Sleep++ The details in the app are great, but the one piece of info that I really wish I could get at a glance is the “readiness score.” Have I overlooked…
★★★★★ I've enjoyed this app for many years however the past couple of years the morning sleep summary stopped working.

I do very much like this app but I wish there was something for shift workers 🤷♀️. I’ll continue to manually put us to sleep as it cannot incorporate a shift worker’s schedule. /Ang… I’m still working shift work & nothing still works for shift workers
Had this app for years now all of a sudden you have to pay to see your sleep score. Unreal.
App has been great for years, tolerated ads and now you want to paywall my sleep history in the app??? Absolutely unacceptable, do not install.
What’s the point of the app if there’s no watch interface? Not sure what your expectations are, but since the Apple sleep feature is more robust, I guess it doesn’t matter, so it’s a useless app
Won’t read “active energy” no matter how many times you toggle it off/on in the apple health app
Seems kinda goofy that I can’t access my history anymore. I’ve got years of data on this app and now I can’t even view it all :/
