Comments on Triangle Calculator for Android

★★★★★ Peter Nichols · Jan 30, 2023

This app quickly solves all unknowns for ANY triangle with any three known inputs; lengths or angles

★★★★★ Jordz Nel · Aug 23, 2022

I'm not a robot or just saying this for fun but this app is really, really good and easy to use

★★★★★ Michael Lucas · Oct 31, 2021

Very useful for solving triangles or double-checking my own guess. It's also fun to just play with odd angles and lengths of sides....

★★★★☆ Mujahid Teli · Dec 5, 2023

This is very good app for finding angle in any trangle

★☆☆☆☆ damian curry · Jul 10, 2025

Useless, doesn't work at all on z fold 6, keyboard covers entry fields, nothing happens when I do manage to make inputs

★☆☆☆☆ Joe Smith · Sep 16, 2021

Woops... Try again. Doesn't solve for missing angle or side.

★☆☆☆☆ Koulang Chey · Apr 7, 2023

Cannot find the right formula in real practice.

★☆☆☆☆ Brian Carrothers · Sep 22, 2022

This app needs more info than hight and width on a 90° triangle. It should be enough.
