Universal Triangle Solver

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 !

Great app but entry blanks don't align with labels. This causes some problems.

Handy app if you're not a math whiz

I use the app often, just wish the owner changed the fusia/pink color to something more readable, like light-blue. I have a lot of trouble with any shade of red. Also, PLEASE fix the boxes on startup so that they clear themselves when you touch the box or take out all the zeros in the startup except one. That's way too much to gave to clear out. Thanks. If not for the above mentioned, I'd give it a 5☆ rating.

This is exactly what i want. Only one thing which has been bothering me since a long time now is that once we clear the things, the values are set to 10.00 as default. One needs backspace the digits to enter new values... I want the sides length to be blank when we press clear button so that we can directly enter new values and dont have to back space default values...

I really like this little app, I love the visual display and the way you can change the orientation of the triangle. I would give it 5 stars if you could purchase an ad free version of the app, and if you got rid of the pre population of the fields, as you have to delete them before you can input your own figures.

I am a machinist by trade and have used this calculator for a few yrs now and it's great! I don't have to think twice about it's reliability like I remember a different trig app had. I have run many thousands of worth of parts off this app and I can't remember correctly how to sohcahtoa! Great app!

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 Side situation.

Terrible ui, does not look like the photos, and not very user friendly. It took longer to check answers with this app than it did solving them in the first place. There are much better versions out there.

nis. p. May 7, 2018     

It is just ok, It have two negative problm 1. It canot zoom because if smoll distance in one side we can't sea the measurements 2. Solved values not showing seperate like another apps

nei. o. Dec 29, 2014     

Does not give accurate answers.difficult and cumbersome user input,my rateing is zero

Jay. K. G. Apr 27, 2017     

In Samsung s7 edge it is not working properly, pls fix

Art. R. May 25, 2016     

It should start at 0. Pain to have to clear each cell before entering

Great app. Covers all triangles and ads dont get in the way.

Kyl. B. Oct 4, 2015     

It's great. Does what I was looking for. Just wish it would save the inputs.

This is as good as it gets. Unix philosophy... Do one thing and do it well.

Ada. M. May 20, 2015     

Works great, simple, adds are placed out of the way of the important bits.

Jac. G. Feb 8, 2016     

Uses very little space, works great, does its job well.

I can calculate the area of triangles

If it had mils it would have been perfect

Very cool, swipe to move the triangle to different orientation
