## Description

Tone Generator is a versatile tool for electronics testing and music preparation. It can generate multiple waveforms with adjustable frequency and amplitude to test amplifiers, filters, and other circuits, and it's also useful for musicians to tune instruments using real-time pitch recognition.

The app includes a built-in tuner (notes from C1-C8) with pitch display, a metronome for steady tempo, stereo left/right channels, and the ability to create, save, load, and export tone sequences (including .caf). Optional features (purchase) add ad-free use, manual frequency input, Bluetooth support for connected devices, white/pink noise, and more. Note: hearing-test results are stored temporarily and can be shared after guidance.

## Review summary

Tone generator is praised for reliably producing tones and being useful for testing audio equipment or teaching sound concepts; it is easy to use and supports high frequencies. However, intrusive full-screen ads, paid upgrade issues and suspected scams, crashes/exports problems, and imprecise tone controls with no volume adjustment heavily color the experience.

### Pros

- Reliable tone generation that works consistently
- Useful for testing audio equipment and studying sound
- Simple, easy-to-use interface without unnecessary bells and whistles
- Capable of high-frequency output beyond basic ranges
- Positive reports of benefits for sleep and tremor relief for some users

### Cons

- Intrusive full-screen ads disrupt usage and cover the screen
- Paid upgrade practices and reports of scams/no clear value for paid features
- Crashes or instability, especially around exporting after payment
- Difficult to precisely tune frequencies due to imprecise slider controls
- No adjustable volume or amplitude controls (volume control is missing)
