Show HN: Created a brain entrainment app – didn't expect growth

https://apps.apple.com/us/app/shimmr-binaural-beats-focus/id6479964631
3•Boxfreshpidge•3h ago
I used to work as an audio engineer and have been meditating for ~17 years. A few years back I started digging into brainwave entrainment — reading older research, patent filings, and papers (like those from the Monroe Institute), and experimenting with tone layering and sound design.

What started as a personal experiment and a way to learn iOS dev ended up becoming a full brainwave entrainment app, now live on the App Store. I released it last year after a few friends tried it and wanted their own version. It now gets several thousand users a month.

I know it's a saturated market but as I said it was only ever meant for me, but I do feel its pretty powerful app and sound wise it seems to work very well!

All the sound is generated and processed within the app — nothing is streamed. I built a flexible engine that lets each preset go through a full audio chain: compression, EQ shaping, stereo field manipulation, Haas effect, binaural panning, and reverb modulation.

So the app is incredibly flexible to attach more complex sounds in the future.

I am pretty happy with it. Please let me know what you think and if you have any cool info regarding Brain entrainment
