## Review summary

Users praise the app for its simplicity and strong conversion capabilities (metric/standard/ISO and US units) and its free baseline access. However, it faces repeated criticism over updates that degrade usability, intrusive ads (often with loud audio), a steep premium price for an ad-free version, and the removal or reduction of convenient features (like saving frequent conversions and easy input editing). These recurring issues drive many long-time users to reconsider or seek alternatives, despite the core functionality remaining solid.

### Pros

- Easy to use and intuitive
- Very useful for metric/standard/ISO conversions and US measurements
- Reliable over years; simple and efficient for frequent use
- Free to use (basic version) and provides essential conversion functionality

### Cons

- Ads and intrusive advertising (including autoplay audio/video) disrupt usage
- Latest updates degraded UI/UX and made the app less friendly to navigate
- High price for ad-free/premium version (reported around $25); perceived as overpriced
- Loss of convenient features (e.g., no easy way to save most-used conversions and limited input/edit options)
