Tired of dealing with Pythagoras theorem, law of sines, law of cosines and other trigonometric formulas? TriangleCalc lets you easily calculate any oblique, right-angled or isosceles triangle. Just select the sides and angles given, type in the values and if the number of inputs is sufficient to solve the triangle, the application does the rest for you. Its as simple as that. In addition, TriangleCalc lets you lock up to two values, so that they will not be erased if you start a new calculation. This feature is especially useful if you want to calculate a number of variants of your triangle.

Pros and cons of TriangleCalc app for iPhone and iPad

TriangleCalc app good for

This app has a clean, easy to use interface. Works as advertised.

I like this app, it works well but there should be an option for feet and inches and fractions if an inch then it will be worth 5 stars

Some bad moments

Ive DL over a hundred apps, but this is the first review Ive written. After teaching myself basic trig via Wikipedia and doing the math, then showing my results to a friend, he said that he bet there was an app for all that. He was right. I tried three other triangle apps, but this one was the best! And it confirmed that I had a minor error in my calculations. This apps is extremely ease to use! I dont have a single complaint at all. Nice work on this app! Im loving it!

I have two other triangle calks on my phone, this one is the best. Easy to use and gives me all the data I need for my day to day needs.

I was kinda reluctant when I was looking at this app but I decided to buy it and Im glad I did! This app has helped me so much in my trigonometry class! Great buy for a dollar!

The triangle is totally useful. You dont have to do any of that silly crap with Pi and all those weird Greek symbols or muck about with some lame calculator app you need an MIT degree to use. Just plug in the angles or the side lengths and the rest of the calculations are done. Very useful, very handy app.

This is nice app and the developer is very responsive to answering any questions and helping you .... i highly recommend this app .... the GUI is the best in the app store in my opinion

I tried free triangle solvers... Those all were horrible. I tried this one, and it was like the gates of heaven opened up! :D
