## Review summary

Users find the Water Flow Calculators app to be a simple, quick, and powerful tool for friction loss and pump operation calculations. However, multiple reviews highlight issues with app stability, such as difficulty exiting the app and needing to force close. Users also desire additional features like elevation options, customizable hose sizes and coefficients, and default nozzle pressures. Overall, while useful, the app requires improvements in functionality and stability to better meet user needs.

### Pros

- Simple and quick friction loss calculator
- Very useful and powerful tool for pump operations
- Informative and handy app
- Good for quick calculations

### Cons

- App crashes or cannot exit properly (needs force close)
- Lacks certain features like elevation option and customizable hose sizes
- Does not default to standard nozzle pressures when selecting options
- Needs ability to change coefficients for different hose brands
