Binaural works well.
Binaural beats can help you relax, meditate, sleep, or even concentrate.
Binaural is the simplest, easiest to use binaural beats generator. Just pick a frequency, hit play, and it’ll do the rest.
I took a short break before a final hour of work this afternoon. Selecting an alpha frequency and medium rain setting, I placed headphones on my ears, sat in our comfortable bamboo rattan chair (which can lean back and rock a bit), and passed out within a few moments for fifteen minutes.1 After the noise stopped, I woke up and felt refreshed. Incredible, and free. Give it a try.
Aside: I wrote this post a few months ago.
- I used the built–in timer in the Clock app. For the option When Timer Ends, choose “Stop Playing”. Binaural also has a timer if you buy the IAP for $2.99. I wrote this before the feature was added on November 12, 2014. ↩
