Store description excerpt
One button. No ads. No subscription. No account. Press it and deep brown noise flows within a second. Buy once, keep forever. Three sounds — brown, pink, white. Swipe to switch. Everything is generated on your device in real time: no audio files, no streaming, no loop seams. Private by design: Hum never uses the network. No tracking, no sign-up, no cloud. Nothing leaves your phone. • Background playback with Lock Screen & Control Center controls • Lock Screen widget — toggle without opening the app • Sleep timer with a gentle fade-out • Volume tuned for the low, quiet range that noise needs
