## What is Pocket Tone?

Pocket Tone is a small, tactile frequency generator for people who use steady tones to settle in, focus, meditate, tune a room, or explore classic solfeggio frequencies.

Pocket Tone generates a clean sine wave in real time, with smooth transitions, background playback, and AirPlay support when you want to listen through external speakers.

Features:
• 432 Hz and solfeggio-inspired presets
• Custom frequency entry up to 20,000 Hz
• Real-time pure sine wave generation
• Smooth tactile dial with haptic feedback
• Background audio playback
• AirPlay and external speaker routing
• Minimal hardware-inspired interface

Use Pocket Tone for meditation, focus sessions, relaxation, sound exploration, speaker testing, or your own frequency rituals.

Pocket Tone is designed for relaxation, meditation, focus, and personal sound exploration.

Spin the dial to jump between 111, 174, 396, 417, 432, 528, 639, and 963 Hz, or slide open the keypad and type any custom frequency up to 20,000 Hz.
