Comments on Universal Triangle Solver for Android

★★★★☆ A Google User · Nov 15, 2014

Needs changes to font and layout for 5 stars Intuitive to use and seems accurate so far. Useful for quick checks on surveying and engineering calculations. I have only tested it in degrees setting so far. I use it mostly on a Sony tablet and wish it could be used in landscape mode. The triangle could be centered higher and the entry fields much larger. Sometimes the data entered scrolls off-screen, making it difficult to confirm an entry. It seems laid out for smaller screens. The ads at the top are not too intrusive, but they do make it hard to concentrate. Maybe instead of constantly changing, they could pop up when a new calculation is performed. I dislike that fields are prefilled by default. The area calculation is very useful. I want to try grad values, but I cannot find the menu and settings button. I have not tried any similar apps as this one serves my needs.

I am a machinist and this app helps me all the time. Super easy to use as well.

Solves triangles with 3 pieces of info. This is a neat tool that lets you input 3 pieces of information (angles & sides) and gives you the rest of the unknowns. Of course 3 angles alone won't be useful, but it will give both possible options if you have an Angle Side situation.

Description by Ctoutpris Written by the developer, not by AppBrain. Click to read.

This application is an universal calculator for triangles. When you give three parameters (sides or angles), this tool computes the remaining parameters and the area of triangle.
The triangle thus determined is displayed with its height.

It works with any right or non-right triangle, including the ambiguous case of the law of sines (the two solutions are given). Support angles in degrees, radians and grads.

Useful for trigonometry, roof computations, math, homework or CNC.

Feel free to email developer to request features, localizations, or anything else !

Simple and effective, and available for free !

Recent changes:
- Add context menu with new settings, to replace the options menu which was not accessible on some devices which don't have a menu button.
- Screen orientation can be changed in settings.
- The "second solution" is accessible only when there is one.
- Added the triangle height. It can be disabled in settings.
- Some other minor improvements.
