Brain.fm is a free productivity app for iPhone that offers science-backed music that enhances focus, improves sleep, and reduces stress and anxiety. The app uses sound to change your brainwave patterns, so you can drop into deep focus or fall asleep faster, every time. With the new ADHD mode, the app now offers extra stimulation to help ADHD brains focus better.

The app offers personalized music for your brain type, tons of genres from LoFi beats to Classical, and even Nature soundscapes. The stimulation level is adjustable, with a boost option for ADHD brains. It also comes with a Pomodoro mode for productivity sprints.

Brain.fm includes focus modes optimized for deep work, learning, creativity, and more, relax modes made to help you recharge during the day or unwind in the evening, meditation modes including both guided and unguided meditations, and sleep modes including guided sleep and energizing wakeup.

The app is funded by the National Science Foundation (USA) and uses patented tech via brainwave entrainment, which has been tested extensively with funding from the US government.
