Wave is too loud, music is too low volume. Nothing compared to what you showcase in live meditation. Would love if there was a way to make wave sound as light as possible. ### 3/5 — Love the brain waves but too many glitches! *2023-05-25* This would be my favorite sleep app if only it worked consistently! I am so frustrated that the brain wave sound only (no music or rain sound), my strong preference, will not give me audio on my 2017 iPad Pro without using headphones, not practical for sleep! Looked for something in settings to change this but found nothing. So I use it on my iPhone 11, but most nights I have to reboot the phone or clear all background apps or both to get the audio portion of the brain waves only—and since my insomnia occurs in the middle of the night, it wakes me up more to have to troubleshoot this app! That said, when I get it to work, it is an almost magical sleep aid! I just wish I could get it to give me audio on my iPad. Have never had this problem with any other app. I would pay for the upgraded version if I thought it would perform the way it should— but then again, all I seek is the most basic function on this app, and for it to deliver that shouldn’t require a paid upgrade, especially with no certainty that it would even eliminate the performance flaws. ### 4/5 — User Dw *2021-12-16, version 2.2.4* 👍👍👍👍 ### 2/5 — Ads stop it from working *2021-08-03* Ever since they started running ads in a banner there have been issues. Now more often than not it stops all sound when certain ads (ALWAYS the Calm App ad) run. Sometimes it just doesn’t make any sound at all. ### 2/5 — Monthly fee- no way! *2021-01-16* The previous app worked ok. This one lets you try just about nothing unless you submit to monthly withdrawals. NOT going to even try doing that. ### 1/5 — Makes me less tired and more stressed out *2018-12-10* The main part of the ONE song you get is relaxing until it loops to a sound that evokes the same thing as nails on a chalk board; it’s like an electronic bird chirping. For the $3 that’s required to download the app you should have more than one song option. To get access to more than one song you have to pay even more money, but don’t even get to preview them to see if the chirping is omitted. So disappointing. ### 4/5 — Great App! *2018-03-26* I have had trouble sleeping, so I decided to try a app and it helps so much. The waves as well as the rain background helps so much. Would be 5/5 if it had iPhone X accommodation. ### 3/5 — Very basic *2018-01-12* Nice basic brainwave app, not a ton of distracting bells & whistles. However, I wanted some features from the upgrade, and it won’t actually upgrade. ### 5/5 — LOVE IT!! *2017-08-24, version 1.0* I love this app! ### 1/5 — Steer Clear *2017-07-16* Please do not get this. It truly limits you from getting true deep sleep! Then you wake up and have a problem with yawning and need to take a nap. Unless you want to create an impulse to sleep through life, turn to other way... ## Most critical reviews (10 lowest-rated) ### 1/5 — Not happy with changes *2025-05-03* The upped the price and reduced the value. The timer doesn’t work. I no longer have the same options as before for music choices. And it’s more expensive than it used to be. Wanting to find a replacement. ### 1/5 — Why would you remove the original music *2025-05-02* I loved the original delta waves music I’ve been using it for a while why did you remove it I don’t like the new one. Please bring the old one back ### 1/5 — Not happy *2020-12-23, version 2.2.3* Not happy that I had paid for the premium on the old version and now have to pay monthly. 🙁 ### 1/5 — Delta *2020-11-09, version 2.2.2* Seems like a good idea, but I doesn’t work properly or I don’t know how to use it and there are no instructions Overall very poor ### 1/5 — Most recent update horrible!! *2020-10-23* You now can’t have it playing in background. Kills battery. And the customer support hi from them keeps writing please email us to correct problems. I have several times and they have yet to respond or reach out. They will not help they try to give good presence but do nothing to fix! **Developer response:** [Update] Hi Stopmadness!

Equilibrium Apps Team ### 1/5 — NEW UPDATE REMOVED BACKGROUND PLAY! *2020-10-17* Very upset, the free version of the app only has 2 songs which I loved listening to every night to help me sleep... However, the new update now has banner ads.. but the WORST thing is now you CANNOT play the sound while the screen is off! You must leave the screen on to play the sound which makes it useless for me now... The app is ruined and unfortunately, I cannot use it if I can't turn off the screen (the battery will drain badly and the phone screen will get damaged from leaving it on all night)... Not happy about it, I have used the free version of this app for years.. this is absolutely appalling.. you have to pay a membership for this app... very disappointed, this was actually my favorite app for sleep despite only having 1-2 free songs... **Developer response:** [Update] Hi Jeff Pham!

Equilibrium Apps Team ### 1/5 — Paid for full subscription - now null *2020-07-29* I’m a bit disappointed. I paid for the full version of the app 3 months ago and after a routine update all the extra features I paid for in the new version are gone and now a part of delta waves 2.1 update. **Developer response:** Hi edchack!

Equilibrium Apps Team ### 1/5 — Delta Waves *2019-04-30, version 1.0* Bought the add on won’t work can’t contact support their comments are closed? ### 1/5 — Scam *2019-03-13, version 1.0* I paid for the full version and it won’t give me access to the full version ## Most praised reviews (10 highest-rated) ### 5/5 — So much improved and thank you *2025-05-11, version 3.0.2* Great app, loved it before as a sleep and relax workhorse. Now it’s a whole new universe to explore. It s my must go to every night 🙏😊 ### 5/5 — Delta sleep *2023-03-28, version 2.2.4* Best sleep I ever had ### 5/5 — The Delta Waves really do Make Me Sleepy *2023-03-08* I have so much trouble getting these apps to work for me. It’s very confusing how to find one and then be able to have it run long enough to keep you asleep for the night. I don’t like it when they stop and change. It wakes me up. I’m still working on it, but this one has good music, or delta waves, and I think it’s running long enough so that I can stay asleep. ### 5/5 — Great app to assist with sleep *2021-07-09, version 2.2.4* I use this app nightly after it was recommended to me by a brain specialist. When I wake in the night I use it to fall back to sleep. Can you make the app operational when the phone is locked please? Give users the choice in the settings at least. Forcing the screen on only drains the battery and makes unnecessary light in the night. It’s counter intuitive as phone light reduces melatonin production. Great app and concept. Keep up the good work. ### 5/5 — Best app for delta waves *2019-05-24* I’ve been using this app for a while now, I love the basic set up!! I fall asleep a lot harder then I normally do especially with my insomnia, it helps me sleep like a baby, I like that you can chose to just have the delta waves ### 5/5 — Power napping *2019-03-08* I’ve been using this app for years, I find it very useful for napping. It’s very simple and doesn’t have ads. Seems almost like a relic from a time when apps weren’t bloated and didn't have all the invasive social media plugins and tracking ### 5/5 — Great...BUT... *2018-07-28, version 1.0* ... Can you have it that when adjusting the wave itself we can see what the hz rating is at? ### 5/5 — I like it *2018-07-27, version 1.0* Wish I could manage the volume of delta waves too ### 5/5 — Helped me sleep deeper *2017-12-20, version 1.0* I tried it out of curiosity after watching a TED about delta waves and deep sleep but it really worked! It doesn't put me to sleep but it helps me sleep deeper. I used to wake up in the middle of the night and stay hours awake. With this app, i sleep the whole night. I have been using it for 2 weeks and I can see the difference. Great App!!!! ### 5/5 — Works great! *2017-10-27* I had a hard time sleeping when I got the piles. I played this at night and fell asleep right away. 2nd night I was still awake. No biggie I set it to 10 minutes and it worked. If you ever wake up in the middle of the night and can't go back to sleep, don't play Candy Crush or read a book, just play this app instead! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
