About this app

Studying, working, or taking a short break — pick and mix the sounds that
fit the moment.

The app is built from two kinds of sound: "core sounds" — binaural beats
(two slightly different tones, one per ear) and white/pink noise, tuned
across bands from gamma (40Hz) down to delta (3Hz) — and "ambience": natural
recordings like rain, ocean waves, and a crackling fireplace. Mix the two
freely to build your own combination.

✦ Key features
- 9 core sounds + 12 ambience sounds, play several at once with individual
volume control
- Pomodoro timer to manage focus and break periods
- Save your favorite combinations as presets
- Track today's and total focus time
- Keeps playing in the background even with the screen off

✦ Being upfront with you
Research on how binaural beats affect focus is still ongoing, and results
can vary from person to person. This isn't an app that promises guaranteed
results — it's a tool for comfortably experimenting with different
frequency bands and natural sounds.

One new core sound unlocks for free every month, and all 12 ambience
sounds are free.
