I have to be honest when Dr. Schmalz, a clinical psychologist (if you didn’t know) recommended Binural tones I brushed it off as a strange not going to help app. Well I tried it, thought it was extremely weird. I doubted it but kept it going. Somehow a half hour later I was clam, so calm I was sleeping. ME the bipolar manic anxiety person who always had diificulty sleeping (as in final sleeping for more than 10 mins at 5:30a and has a toddler that is beyond up no later then 7:30a. Needless to say I continued using it. Now I don’t necessarily use it every night. But I do when I’m struggling with sleep again and started using it through the day to relieve stress and anxiety and relax and be able to focus (helps my ADHD also). I am not usually a person to use something like this or I would use it once and never again, I might think about it but constantly slips my mind. However, this app is AMAZING. I more then recommend it, I now also use it with my 14yr old son. Helps him focus before and during COVID-19. He is diagnosed DMDD, ADHD, unspecified mood disorder, sensory processing disorder, anxiety, specified learning disability and Executive Functiong. He’s a lot, but this app has helped him more than I anticipated!!!!! At least give it a try even if you doubt it initially try a few more time, YOU WILL LOVE IT!!!

I urge you to try this app.

I never really paid attention to these sorts of sleep strategies - I know that if I concentrated on relaxing for example, I would fall asleep - sometimes. Some would call that meditation - maybe that is what it is, but its not always easy to “turn off” my racing thoughts. But the binaural effect that this app produced was quite dramatic, and this particular app consistently helps me drop off to sleep in a very short time, regardless of the chaos of my day. I would urge you to try it, play with the various settings to find a sound pattern you enjoy. I did just that, and never looked back. I’m a cynical person, but I was so pleasantly surprised with the effectiveness of this app. It is very easy to use - I applaud the clean minimalist interface, and the dark mode. You’ve got nothing to lose by trying this app. After using it for quite some time I ponied up with a payment, for no other reason than “a job well-done”! Thanks!

Best one that's free with auto frequency change

I downloaded about 6 different binaural sound apps this one is the best. In order for this to work you have to have headphones!
2nd app on my list is iMeditate that's if you like the sounds of munks praying. I think it's cool but too distracting for me.
This app has 2 required features that not all apps had.
Best feature is to automatically adjust the frequency to a final slower frequency.
This could be achieved quickly or slowly, you pick.
<< I usually set it to 10 min.>
2nd feature is to basically stop after a certain amount of time.
**Initially you have to find the sound that tickles your brain (should be high frequency since you're awake & everyday will be different), then the freq. as it slows down will gradually make your brain slow down too.
Funny thing is that I wake up as if I had a really good sleep each time. No head aches! I'm glad I didn't spent $200 on a beanie with headphones & brain wave sensor. Because this free app works.
