Focus Tunes
Focus sounds that stay out of the way.
A focus-sound app for iOS and Android. Layer ambience and noise, run a pomodoro timer, or dial in a tone, then leave it playing in the background while you work. The core is free, there is no account, and nothing you listen to is tied to you.
Layer your own mix
Play several sounds at once, each with its own volume, and save the mix you keep coming back to.
Pomodoro and session timers
A timer with presets and a fade-out, so a session ends instead of cutting off.
Tone generator
Presets plus a custom frequency, synthesised live on the device rather than shipped as audio files.
Background playback
Audio keeps going with the screen off, with play, pause and stop on the lock screen.
Offline by default
Every feature works with no network. The only traffic is optional usage counts, crash reports, and store purchases.
Free core, no subscription
Mixer, timers, tones and the base catalogue are free. Optional sound packs and tips are one-time purchases, never a subscription.
