Brain.fm

Brain.fm sells something narrower and more honest than most "focus music" apps: functional audio engineered with rhythmic modulation intended to support attention, relaxation, or sleep, rather than just curated playlists. The distinction is real — tracks are built to fade into the background without lyrics or hooks to grab your attention, and many users (particularly people with ADHD) report it genuinely helps them settle into work. The company also invests in research and has collaborated with neuroscientists, which is more than most competitors do, though it's worth being clear-eyed: the supporting evidence is promising and growing rather than definitively settled, and effects vary a lot from person to person. Practically, it's a focused, no-frills product — pick a goal (focus, relax, sleep), pick a vibe, press play — on web, iOS, and Android with offline downloads. At $9.99/month or $49.99/year it's priced like a premium single-purpose app, and the free trial is the right way to find out if your brain responds, because some people feel a clear difference and others feel nothing. If background music already helps you concentrate, Brain.fm is a worthwhile upgrade to try; if you need silence to focus, no audio tool will change that.
