About this app

FlowLock uses scientifically-backed binaural beat audio to help your brain reach specific mental states — deep focus, creative flow, relaxed alertness, or sleep — on demand.

HOW IT WORKS
Binaural beats work by playing two slightly different frequencies in each ear. Your brain perceives the difference as a rhythmic pulse, naturally guiding your brainwaves toward your target state. No caffeine. No crash.

WHAT'S INSIDE
- Focus Mode — Alpha and Beta waves for sharp concentration and task completion
- Flow Mode — Theta waves for creative deep work and problem solving
- Relax Mode — Alpha waves for calm, present-moment awareness
- Sleep Mode — Delta waves for deep rest and recovery
- Built-in timer with session tracking
- Clean, distraction-free interface

WHO IT'S FOR
Students pulling long study sessions. Professionals doing deep work. Creators in the zone. Athletes in pre-competition mental prep. Anyone who wants to get more out of their focused hours.
