Altune: Focus, Relax, Sleep

There is a strange economy around calm. Breathing apps, focus apps, sleep sounds — most of them cost somewhere between five and fifteen a month, forever, for audio and a timer. Altune is the same category, bought once. FOCUS Sound environments built around 40 Hz gamma frequencies, layered under ambient settings — a coffee shop, a train interior. Consistent sound with no lyrics and no sudden changes, which is a reliable way to hold attention. A Pomodoro timer is built in, so the sound and the work interval are the same thing. RESET Guided box breathing — four in, four hold, four out, four hold — with a visual guide. Two minutes before something stressful does more than telling yourself to relax. SLEEP Slower delta-range soundscapes with a timer, so it stops on its own. For the three a.m. version of the problem, where you are awake and your head is going through tomorrow. TRENDS Lifetime completed minutes, if you want to see it. RUNS ON YOUR DEVICE No account, no sign-up, nothing uploaded, no ads. A note on the science: research on gamma entrainment and binaural beats is real but early, and the effects are modest. Altune describes what the sound does, not what it cures. It is a tool for focus and rest, not a treatment for anything. One-time purchase. No subscription.
