## Description

The Universal Triangle Solver is a free and versatile Chrome extension designed to compute all unknown parameters of any triangle when provided with three known sides or angles. Whether you're working with right or non-right triangles, including ambiguous cases under the law of sines, this tool delivers accurate results efficiently.

It supports angle measurements in degrees, radians, and grads, making it ideal for students, professionals, and hobbyists engaged in trigonometry, math homework, roofing calculations, or CNC programming. The solver also visually displays the triangle along with its height for better understanding. Simple yet powerful, this extension is a must-have for anyone dealing with triangles.

## Review summary

Users praise the app as an invaluable, reliable triangle solver that quickly computes missing sides/angles from three inputs and offers a good visual display. However, it faces recurring issues with compatibility on newer Android versions/devices, occasional functional outages, and a user experience plagued by UI misalignment, readability problems, and annoying default field behavior. The core functionality is strong, but platform compatibility and usability are the main pain points.

### Pros

- Invaluable triangle solver used daily; reliable and handy.
- Accurately computes missing sides/angles from three inputs and handles different configurations.
- Saves time and is easy to use for both math novices and professionals.
- Clear visual display with adjustable triangle orientation.
- Long-term reliability; trusted by users for years.

### Cons

- Compatibility/updates issue: stops working on newer Android versions or devices (e.g., Vivo V40).
- App sometimes becomes unusable or stops functioning.
- Poor UI/UX with misaligned inputs, inconsistent visuals, and readability/color problems.
- Cumbersome startup behavior: default values (e.g., 10.00) auto-fill and must be cleared; fields aren’t cleared on start.
