## Description

Tone Generator EX is a compact audio tool that generates tones across a wide frequency range (15 Hz to 22 kHz) using four classic waveforms: Sine, Square, Sawtooth, and Triangle. It supports background playback and convenient controls from the notification area or headset buttons, plus an auto-off timer for power management.

Users can create and save their own presets, tune frequencies by musical notes, and enjoy auto-pause on incoming calls or alarms. This extension is ideal for sound testing, music/app development, and educational demonstrations.

## Review summary

Tone Generator EX is praised as a free, ad-free, accurate sine-wave generator with a clean, responsive interface. It’s valued for tuning, calibration, and musical reference, and for precise frequency entry and a built-in keyboard. Top cons focus on its outdated status, limited low-frequency range, and absence of export/sweep saving and DAW plugin support.

### Pros

- Free and ad-free; no nag screens or subscriptions
- Accurate sine-wave tones suitable for calibration and tuning
- Clean, intuitive UI that feels responsive and musically oriented
- Precise frequency entry with decimal support (two decimals)
- Built-in keyboard to hear notes and view exact frequencies

### Cons

- Outdated/not updated recently; potential compatibility risks with newer iPadOS
- Low end frequency limit (~15 Hz); users request lower ranges (down to 10 Hz or 0–12 Hz)
- Lacks export/save of created tones and sweeps and missing DAW plugin support (no VST3/AUv3)
