Braintunes - Focus music that uses real neuroscience, not binaural beats

by•
I kept trying focus music apps and they all had the same problem: either they're just playlists with a "focus" label, or they want $10/month for rain sounds. Braintunes uses amplitude modulation at target brainwave frequencies — the same technique a 2024 Nature study found boosted focus brainwaves by 119%. Four modes (Focus, Relax, Sleep, Meditate), three intensity levels, sleep timer. Free, no ads, no subscription. Web, iOS, Android.

Hey — I'm Aleks, I built this. Quick backstory: I was using various focus/sleep apps for years and got increasingly frustrated. Most of them are either glorified Spotify playlists or subscription traps that gate basic features behind a paywall. And the "binaural beats" ones — I dug into the research and found that the evidence for binaural beats is actually pretty weak (only 5 of 14 studies in a 2023 review supported them). So I went down a rabbit hole on neural entrainment research and found that amplitude modulation — basically rhythmic volume pulsing at a target frequency — produces much stronger brain synchronization. There's a solid 2024 study from Northeastern's MIND Lab (published in Nature's Communications Biology) that backed this up with EEG and fMRI data. Built Braintunes around that approach. The music itself is AI-generated to be genuinely boring in the best way — no vocals, no sudden changes, just warm ambient textures that stay in the background. I made it free because I wanted people to actually try it, not bounce off a paywall. Try the web app first — takes about 10 seconds to get sound playing. Curious to hear: do you currently use anything for focus/work music? What made you stick with it or drop it?
