Comments on Fault Current Calculator for Android

★★★★★ A Google User · May 13, 2013

Useful app! This app is very intuitive and easily calculates fault currents for a one line drawing. I like the look and feel as well.

★★★★★ A Google User · Jun 21, 2013

Great app! This is a great app. I like this better than the online fault calculator Bushman used to provide. See you at NTI in Ann Arbor for the Tuesday night presentation!

★★★★★ A Google User · May 14, 2013

Very Easy I like how this app flows. The label feature is a plus.

★★★★☆ McLovin sings · Nov 20, 2025

Neat little calculator for checking fault current along a single system branch. If the app allowed you to create branching one line diagrams, it would be worth paying the subscription. As the app is now, you have to use paper and pen alongside this app any way to create a comprehensive system diagram, so the benefits of saving projects and sending system diagrams are entirely lost.

Can't enter data I've an AT&T Samsung Note 1. Installed software, tried to use it on a 3 phase circuit. When I get to entering kva and voltage, app does not bring up keypad. Long press on entry field does eventually bring it up, but app erases my entry when I try to move to the next field. Uninstalled.

★☆☆☆☆ Michael Furtak · Jun 26, 2015

Inaccurate and impractical Equipment x/r ratios is not taken into account in calculations. Hence, highly inaccurate calculated fault current values. Also, the app is limited to one (1) source only, does not provide for creating real world radial single-line diagrams and does not factor in short circuit current contributions from motors and generators upstream.

★★☆☆☆ Geordie Iselin · Jan 28, 2022

It wants you to fill in every field including aic. It's just a form not a calculator.

Limited MVA for transformers in both the free and subscription versions.
