So much improved and thank you

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 🙏😊

Not happy with changes

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.

Why would you remove the original music

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

Love the brain waves but too many glitches!

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.
