Brain.fm vs Liminal Flow

Brain.fm provides music for focus, sleep, relaxation, and meditation, with modes such as Deep Work, Creativity, Learning, Light Work, and Motivation. The company says its patented neural entrainment technology is designed to guide listeners toward a desired mental state, and that it reduces attention-grabbing elements so the music can remain in the background. Infinite, Timer, and Interval options track work and break periods. Brain.fm describes its music as designed for ADHD and offers a High Neural Effect mode. The maker says it evaluates music using attention tasks and placebo controls, as well as EEG and fMRI studies. The service works on the web, iOS, Android, Windows, and macOS. Desktop downloads list macOS 12+ and Windows 10+, and an internet connection is required. Monthly access costs $14.99 a month; yearly access costs $99.99 a year. Both plans include Focus, Sleep, Relaxation, and Meditation modes across web, mobile, and desktop. A 14-day trial and student plan are available; there is no free plan.
