Comments on Triangle Calculator and Solver for Android

★★★★★ Peter Robert · Apr 25, 2020

Works well. Have all angle units and imperial units too.

★★★★★ Alana Winterveil · Apr 24, 2020

I went through many triangle calculator apps and this is the best one! The only nitpick I have is that the 0s when you clear are actual measures, and you have to delete them to put in the numbers. It doesn't affect the calculation at all, don't worry, but I try to be as efficient as possible, and it takes up just a teensy amount of time. Other than that, the app is perfect! It can be used for any triangle, including right ones!

★☆☆☆☆ Kat Weltha · Jan 20, 2020

Would not give me any values that I did not input myself. Completely useless.

★☆☆☆☆ Jacob · Sep 24, 2020

Awful, occasionally changes what you put in for no rsn and then obviously comes out with the wrong triangle

★☆☆☆☆ Gillian N. · Apr 2, 2020

Suggested that the height of my triangle was greater than any of the sides. Interface is not great, either.
