Our Final Verdict
Brain.fm
Brain.fm is a polished subscription app that uses AI-generated audio to modulate cognitive states. Its music is pleasant and genuinely different from typical lo-fi playlists. However, it operates on a broad 'functional music' premise rather than using specific, targeted gamma-frequency (40Hz) entrainment. The Genius Song's dedication to gamma-range neuroscience for focus and memory consolidation gives it a more evidence-grounded mechanism than Brain.fm's wider but shallower approach.
