Focus better with sound and structure. There are two ways focus tends to break down. One is going too hard for too long — no breaks, no signal to stop, until the energy runs out and recovery takes longer than the work did. The other is the opposite: attention that spreads across too many things at once, never settling deep enough to get real traction. This app is a quiet guide for both. It pairs 40Hz-centered audio — sine waves and noise you can blend and adjust — with Pomodoro-style session timers. The sound gives your mind something steady to anchor to. The timers give your effort a shape: work in a bounded block, then stop on purpose, then return. Not because you collapsed, but because you chose to. WHAT'S INCLUDED 40Hz audio — Sine waves and noise centered around 40Hz. Research suggests this frequency range is associated with alertness and sustained attention, though the effect varies by person. Adjust the frequency and mix until it settles into the background the way you need it to. Sound options — Sine waves, white, pink, or brown noise, or combinations. The goal is a consistent ambient layer that keeps you oriented without pulling you away from what you're doing. Session timers — Pomodoro (25 min work / 5 min break) and other configurable formats. Structured intervals help if you tend to either push past your limit or drift before you've fully arrived. The timer marks when to go deep, and when to genuinely rest. One-screen control — Start, pause, and adjust everything from a single place. Minimal by design. WHO TENDS TO USE IT People who work in long, unbroken stretches and find themselves depleted before the day is done People who sit down to focus but feel their attention thin out before it has a chance to settle Students and remote workers who want a quiet rhythm to structure their sessions around Anyone who already uses Pomodoro or ambient sound, and wants both running together HOW IT WORKS Pick a sound and adjust the blend. Choose a session type or set your own work/break lengths. Start the session — the app handles timing and playback from there. When the timer ends, take the break. Then come back. No ads. No subscription. The app does one thing and tries to do it reliably. If you recognize either pattern — pushing until you're empty, or struggling to land anywhere long enough — it might be worth trying as part of your working rhythm.
