## Review summary

TLV ToolBox is praised as a very useful, easy-to-use pocket tool for steam calculations and TLV alignment. However, users repeatedly report Android UI/screen-fitting issues on several devices and versions, plus a limited feature scope focused mainly on steam calculations, with recommendations to use the website for water or gas calculations.

### Pros

- Very useful tool for steam/power plant calculations.
- Handy pocket tool that's easy to use.
- Exactly what I was looking for and meets user needs.
- Represents TLV well and aligns with TLV standards.

### Cons

- Android UI not fitting the screen: top cropped or partially visible content across multiple devices (e.g., Pixel 7, Galaxy S23/S24, Moto 50 Pro).
- Not optimized for latest Android versions; mobile UI/good viewing experience is inconsistent.
- Steam-only scope: lacks water/gas calculators and other functions; users suggest using the website for those calculations.
