## Review summary

ToneGen is a simple two-tone generator praised for precise frequencies and relaxation use, but user feedback centers on input glitches and lack of presets. Manual entry often fails and the slider’s precision is insufficient for exact Hz. The app also lacks easy preset saving and robust export/support options, which limits repeated use. For those who need exact frequencies and presets, it may be frustrating; others appreciate its basic tone-generation utility.

### Pros

- Supports multiple tones simultaneously (multi-tone capability).
- Generates precise frequencies reported by users (some verified with a meter).
- Useful for relaxation/sleep and ambiance; easy to use for basic tone generation.

### Cons

- Manual frequency entry is glitchy or unusable; the slider is imprecise and backspace may not work.
- No ability to save or name presets; difficulty recalling exact frequencies across sessions.
- Export/share options are limited or unreliable (FTP often not working) and support options are unclear.
