## Review summary

HyTools is praised as a useful and comprehensive tool for heating system calculations, including balancing valves and pipe sizing, mostly appreciated by users familiar with metric units. However, many users report significant issues after updates: critical features like the pipe calculator malfunction, the app fails to open or exits poorly, and the user interface is not intuitive or user-friendly. Lack of clear instructions and support for specific piping materials further limits usability, leading to negative feedback especially concerning app stability and functionality on Android devices.

### Pros

- Useful and fantastic tool for calculating pipe sizes, pressure drops, valve settings, and dirt separation units.
- Includes a balancing valve tool that can assist in adjusting flow rates for heating systems.
- Supports metric measurements, which is suitable for many users outside the USA.
- Long-time positive user experience noted by some users who rely on the app for heating system calculations.

### Cons

- The user interface is difficult to use and unintuitive, especially the balancing valve portion lacking clear clickable areas or instructions.
- Pipe size calculator and other functionalities do not work properly after recent updates, causing frustration.
- The app sometimes fails to open or remains blank on Android devices after updates.
- Lack of support for certain pipe materials (e.g., PPR) and lack of differentiation between open and closed loop piping causes confusion.
- App is perceived as unstable or crashing, with users unable to exit from the latest version.
