I never got to use it not even found it I would recommend do not use
★★★★ Evelyn Torres 6/8/2026
extremely bad the app kept on kicking me out when it was what it told me to do and also when you check your heart rate it burns your finger with the flashlight.

this app freezes and says close window, does not work after I paid a premium price, now they will not refund me. I'm choked. I would not give any stars because of this.

★★★★ John Arnold 4/26/2026 v2.1.2
I already answered about 15 questions si i got out of the app thinking i ciuid judt set it ti track. Wrong. Too invasive. Uninstall.
★★★★ Lisa Drew 4/19/2026

★★★★ Marilynn Dapp 4/9/2026 v2.0.9
not as described. It has logs but was not what I was looking for.
★★★★ S “Grandma” Underwood 4/8/2026 v2.1.0

★★★★ Monica Sangster 4/6/2026 v2.1.0

★★★★ Rana Mini 4/3/2026 v2.0.3
it doesn't do anything
★★★★ Vanessa Harvey 4/1/2026 v2.1.0
tried the last 3 nights, never stays recording the whole night, I wake up and the app is closed, and I dont even get a report of when it is recording
★★★★ Yolanda M Sallard 3/31/2026
wasted time
★★★★ Robyn Martin 3/28/2026 v2.0.9
I am constantly either having trouble turning the recording on or once getting it started I can't find a way to turn it off in the morning so it doesn't track anything. It worked during the trial but isn't now I've paid a subscription.
★★★★ Asher Smith 3/27/2026 v2.0.9
Frequently crashes overnight so I wouldn't get the sleep logs. Also after the 7 day trial they started charging me $10 per week. Not per month.
★★★★ Joan 3/25/2026 v2.0.9
u have to pay.
★★★★ Nauku Maija 3/20/2026 v2.0.9
Didn't record anything despite the fact that I started a recording when I went to bed. Swapped to SleepCycle, which worked fine. First time opening the app is like those online ads that say you'll get a free weight loss/training plan, and then it "calculates your plan" and expects you to pay money. Also has a really horrible white noise option called "cat purring", which is like a repeating 20 second clip of a cat loudly washing itself and licking the mic.
★★★★ Derrick Anderson 3/19/2026
Absurdly expensive subscription model.
★★★★ Estelle Ray 3/16/2026 v2.0.9
I have not used this site but Im being charged. You all made another charge off of my husband's card as well. I Need a refund for every week I've been charged.
★★★★ Jill M 3/14/2026 v2.0.9
This app completely changed my entire home screen and they continue to charge you weekly even after you uninstall it after the free trial. Be careful and read the fine print!
★★★★ Tania Fain 3/12/2026 v2.0.9
does not track sleep even with phone right beside you
★★★★ Kayden Cook 3/11/2026 v2.0.9
it doesn't work for me I'm giving this a 1 star
★★★★ John Inglis 3/10/2026 v2.0.9
They want 60.00/momth after the free trial. I will pass on that. There a lot of "sound machines" they play different sounds to help you sleep. You can purchase for a reasonable price, I've been using one for a few years now when I sleep .
★★★★ Teresa Lewis 3/4/2026 v2.0.8
that's not what I wanted!
★★★★ Karolina Poplawska 3/1/2026
didn't work at all, every time i'd start tracking my sleep when i awoke it would show it didn't log anything at all. just a waste of storage because a lot of it's uses are also locked behind a paywall
★★★★ Çağrı Burçin Gökahmetoğlu 2/28/2026 v2.0.8
the first questionnaire + waving 92 percent improvement part can not be completed no matter how many times i tried
★★★★ GOD 2/27/2026 v2.0.8
this app is a scams it never records anything
★★★★ Wendy DalMonte 2/27/2026 v2.0.8
Terrible app. I had everything set up two nights in a row, only to find out in the morning that it tracks nothing!
★★★★ Jenn Grady 2/26/2026
I tried this app for 4 days . I wear a Garmin Fenix & the results from both were on completely different ends of the spectrum. this app data indicated 3 hours while Garmin data indicated 9+ hours. I wanted to see if I snore/talk in my sleep.most things logged as talking or snoring. none of which were either . most were pet noises.
★★★★ Miha Pucelj 2/23/2026 v2.0.7
There is no free trial. every action brings up "pay us 10€/week" screen. keep away from this
★★★★ Jess D 2/20/2026 v2.0.7
As far as I can tell it dont work. App must have forced its self closed at night, woke up excited to see only to find the app at somepoint completely gave up and didnt even save what it already had. Happened 2 nights in a row and you want $10/month? TFOH.
★★★★ A Google user 2/19/2026 v2.0.7
this app is not freaking for me I go to sleep it's in you stay up for 3 and 4 hours The North is so loud this apps I just delete it this apps is suck they told me you just wake up it just my dog just barking in the room it's pretty bad 1/10👎👎👎👎👎
★★★★ FreeState Rifle 2/17/2026
tired of these fake free apps that want to charge $365 a year.
★★★★ Guy Roy 2/15/2026 v2.0.7
I couldn't even get the app to record anything.
★★★★ Alec Heesacker 2/13/2026
I can't sleep very well without a night light due to Half-Asleep Hallucinations! That's my complaint!
★★★★ Alfreda Neely-Sawyer 2/13/2026 v2.0.7
never worked
★★★★ Jordan “조던” Thompson 2/12/2026 v2.0.7
doesn't seem to work on S25. I do heart rate, start cycle, days recording. go to sleep, wake up, nothing recorded, asks to start a cycle to record shatatics.
★★★★ Cj Mcfly92 2/10/2026 v2.0.7
the very first thing said that it was free it's not free
★★★★ Mohand ali (Mohand ali abdallah balal) 2/9/2026 v2.0.4
free bad, a lot of ads show
★★★★ Stephanie B 2/9/2026 v2.0.6
canceled before subscription ended, no support in app and was still charged, this app isnt affiliated with remly.
★★★★ Боян Бановски 2/8/2026
Extremely inaccurate
★★★★ Carol Warland 2/7/2026
The heart rate feature doesn't work on this app, nor does the app itself. I checked my phone now at 04.03 and it had turned itself off and nothing was tracked! A rubbish app and definitely don't pay for it! At first, it wouldn't let me cancel my subscription and I had to try 3 times before it would allow me to do this!
★★★★ Dima 2/6/2026 v2.0.6
Horrible, when I woke up, my sleep was not recorded neither the white noise . I will uninstall it.
★★★★★ Ryan Ryan 4/17/2026 v2.1.0
I keep trying to track my sleep, but the app keeps turning my sleep off in the middle of the night for some reason. I can't figure out how to stop it from doing that. when I go to bed I start tracking, but when I wake up it's like I never did it in the first place. it's been doing it the last four nights in a row
