Description by WonHyeong Chang (from the App Store)
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 and Home Screen widgets — toggle without opening the app
• Sleep timer you set in hours and minutes, with a gentle fade-out
• Volume tuned for the low, quiet range that noise needs
