## Review summary

CellMapper is praised when functioning for its useful network data (signal strength, tower distance, bands) and for its educational value, plus support for user-contributed data. However, it frequently fails to load maps or display towers, regresses in some regions, is unavailable in certain locales, and users face captchas and confusing UI with heavy permission prompts.

### Pros

- Displays signal strength, distance to cell towers, and band information.
- Educational value about cellular networks.
- Allows user-contributed data to improve tower mapping.
- Generally well-regarded and useful when it works.

### Cons

- Map often empty or towers not displayed.
- App reliability issues and regressions; not working in many regions.
- Regional availability restrictions (Australia, UK, other regions).
- Too many requests and captchas causing friction.
- Confusing UI and excessive permission prompts.
