Hi Product Hunt! I discovered this app while searching the iOS store for a simple, consistent, ad-free / minimalist binaural beat app. The problem with other binaural beat apps is that they’re usually not pure beats (they may add rain or other SFX or switch between frequencies), and if they are, they have a lot of ads ruining the flow of listening to a consistent stream. This app is good because you don’t need to pay to enjoy it, it’s simple and easy, and you can change frequencies from the lock screen. I wake up every morning listening to theta waves and sometimes fall asleep with delta. Using gamma waves while working puts me in the flow state faster as well. Thanks to @mipstian for this app. Hope ya’ll enjoy!

nice app
