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. ### 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 🙏😊 ### 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 ### 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. ### 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. ### 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. ### 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. ## Frequently asked questions about Delta Waves+ Sleep & Relax Now ### What does Delta Waves+ do?
