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

★★★★★ Rick Boccardo · Dec 8, 2025

I make stair rail for a living commercial, mostly .... I use this app, almost constantly,,, finds all the 3rd legg of every angle, precisely... the secret to trig

★★★★★ 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....

★★★★★ Jrnayr Lauscap · Mar 20, 2025

Very helpful!!! I recommend this app for those students who are struggling in finding the measurements of a triangle. My teacher recommended this app, it's really a life changing app

★☆☆☆☆ Joe Smith · Sep 16, 2021

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

★☆☆☆☆ Wes Ovall · Aug 28, 2021

Triangle needs to update with variables.

★☆☆☆☆ Brian Carrothers · Sep 22, 2022

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

★☆☆☆☆ 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

★☆☆☆☆ Koulang Chey · Apr 7, 2023

Cannot find the right formula in real practice.
