## Review summary

Users praise Tone Generator! for its simple, affordable interface and ability to generate multiple tones simultaneously across sine, square, and triangle waves. It’s handy for tuning, ear training, and audio testing, with presets. The main drawbacks are that playback doesn’t continue in the background or when the screen sleeps, and frequency entry is clunky since there’s no direct numeric input. Overall, a solid low-cost tool with room for background playback and input improvements.

### Pros

- Simple and straightforward interface; easy to use.
- Excellent value for money (low price).
- Supports multiple tones simultaneously and multiple wave types (sine, square, triangle).
- Useful for tuning, audio testing, and exploring just vs equal temperament.
- Allows saving tones/presets for reuse.

### Cons

- Stops playing when the device locks, goes to sleep, or when switching apps; lacks background playback.
- No direct numeric frequency input; relies on plus/minus steps which is tedious for large frequency changes.
- Getting tones far apart quickly is cumbersome; would benefit from faster controls or a direct frequency input.
