The wake up preset in the app also gets rid of the morning grog. Great job and THANK YOU!!! This app will help a lot of frustrated insomniacs... ### 5/5 — Great app *2011-09-08* Excellent sleep tool!! ### 5/5 — Excellent App. *2011-07-03* I have an extensive collection of Binaural Beat Applications. I have all of Brians apps. There are no Sleep apps better than His. I have only one minor suggestion. The suggestion is that he provides for 8 hours of duration or, better still, run contonuously until a preset in app alarm is triggered. Well Done Brian !!! ### 5/5 — Crazy *2011-05-12* Was referred by a friend who got this and said they were having great sleep and strange dreams. So I picked it up the next day and i've had great sleep and amazing dreams. ### 5/5 — Carol *2011-04-13* Excellent app!!! It is better than any other sleep app! I've tried a bunch. You wake up refreshed and not groggy at all. Love it. Highly recommend ### 5/5 — Amazing *2011-02-23* I bought this around noon, so I was not very tired at all, just wanting to test it out within three seconds of listening I started yawning and the took a three hour nap. When I woke up I felt quit refreshed having had one of the deepest sleeps I've had in a while, coincidence? I think not, I could listen to this again ( I just woke up from my nap ) and go back to bed waking up refreshed again! ### 5/5 — Brilliant *2011-02-19* Great proven interface which is used on other applications made by this person. I like how it operates in a straightforward way. It is not only sleep that is covered by this application...also dreams...and astral projection. Well made with care and attention...also great help page. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not working *2024-10-20* Used to love this app. Not sure what just happened - between yesterday and today - but it will no longer run unless the screen is on the app. So I now have to change the phone setting to never turn off screen. That doesn’t work for many reasons at night. I used to be able to use the wake setting in the background. Now I can’t do that either. It doesn’t even show up as a program on my phone when I search for it. Please fix this ASAP! ### 1/5 — Useless *2020-04-29* Basically spent money for nothing. There are much more apps that do things better and for free. ### 1/5 — Disappointed *2011-10-22* It doesn't play the binaural beats at all, just background noise. Crap and waste of a dollar ### 1/5 — DONT BUY THIS *2011-04-01, version 2.2* All this is terrible!!! "nature and household sounds"????? It's so poorly looped that the bird in the Forrest sounds is repeating the exact same chirp, over and over. It's pure trash and I WANT MY MONEY BACK!!!! 2.00$ for this pathetic garbage? My year old niece could come up with something better...... Pathetic! Total rip off. :(. Don't buy this!!!! ### 2/5 — OK. Look Elsewhere for Better Ones *2013-06-24* Does NOT last long. Can only Program for 4 hours MAX. Well most people sleep more than 4 hours a night. Many sleep 7-9 even 10 hours a night. This App is best for people who take naps **Developer response:** Per the instructions...run for 30 minutes BEFORE going to sleep...jeez😳 ### 3/5 — Not enough for what it is *2011-08-14* Appreciative of simplicity but I need more options. The loops are obvious in the background--a little click in the waves for example--that thwarts my letting go. Glad it works for others. ### 4/5 — a great line of apps! *2011-07-09* Sleep System plus Pain Killer are a potent pair. I look fwd to more time with the other binaural apps by this developer. ### 5/5 — Also my favorite sleep app *2015-08-26* The setting for pain and sleep is fantastic. I also use the wake up setting to get me going in the morning. I love all of Brian's apps. ### 5/5 — My Favorite Sleep App *2013-06-04, version 2.6* I have tried many things to help me sleep. And none are as effective as this. And I love the dryer background noise. I used to sleep on top of the dryer when I was little. Very soothing ### 5/5 — Amazing! *2013-05-30* Best sleep in a long time, thank you :) ## Most praised reviews (7 highest-rated) ### 5/5 — Works well *2013-03-18, version 2.6* I have trouble getting back to sleep at night. After trying different settings it worked very well. I got to sleep fairly quickly. I use a special headband with soft speakers in it that I ordered online ### 5/5 — It Works! *2012-09-01* Best white noise maker. I use often when I nap. ### 5/5 — This is an awesome app *2012-08-28* The sounds are a bit weird, but it totally works. These are not background noise to read or work. They take your total attention, and they work. 'Nite. ### 5/5 — Works! *2012-08-21* Definitely try it if you have chronic pain! Trust me ### 5/5 — Finally some sleep! *2012-08-04, version 2.5* I have always had trouble falling asleep and also staying asleep. I have used prescription sleep aids and over the counter. Some just simply don't work and some do but end up leaving me groggy the next day. After the 3 week of sleeping for only 3 hours at about 4:0 am I down loaded this app. After only 15 minutes with it I was sleeping soundly until 10 am! I never sleep that long. I use it now every night and if I do wake up I just turn it back on, but I haven't had to do that much. I highly recommend this app! ### 5/5 — It Actually Works! *2012-04-06* I suffer from fibromyalgia which usually means many sleepless nights for me. But since this app I am now getting full nights of sleep instead of only 2-3 hours! ### 5/5 — Great App! *2012-04-01* All of this Developers apps are great. Binaural beats are scientifically proven and safe. I have other apps downloaded by other developers but I have found this developers to be the most proficient. I have 2 sets of head phones. The earbuds that came w/ my phone and a richer sound set. For me I have found that the apple earbuds work the best. Pain Killer 2 is another excellent app.... it works. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
