Boilerplate description

Use any portion freely. For coverage assistance, email below.

Freqscope is a precision audio tool for musicians, sound designers, and anyone who wants exact control over frequency — not a mood app, a real signal generator and analyzer that runs entirely on your device. Dial in any frequency from 20 Hz to 2000 Hz with sine, square, triangle, or sawtooth waveforms, or start from the nine classical Solfeggio tones and the A440 tuning reference. Point the built-in analyzer at any sound and Freqscope reads back the exact frequency and musical note in real time — a capability most tone-player apps simply don't have. Save your own presets, browse a full session history, export any tone as an audio file, or run a frequency sweep to ramp smoothly between two frequencies. Unlock Pro for binaural beat mode, unlimited presets and history, and unlimited audio export. No accounts. No internet connection required. No data ever leaves your device.

Founder quote

“Freqscopeis built around one principle: your data stays on your device. We don't want it, we don't store it, and we don't need it to make the app work. Everything that can run locally, does.”
— Peter Zhang, solo developer, Obelisk Club
