Comments on BuildCalc for Android

★★★★★ Sean McGrath · Dec 6, 2023

This app is GREAT! I've had this and Construction Master Pro on my phone for years! But BuildCalc has been the one I choose to use daily! Now with Construction Masters greed BuildCalc is an even better value not to mention a better Calculator! Don't hesitate once you have this on your device you will use it more than you thought you would! Love this app!!

★★★★★ A Google user · May 29, 2016

John Best calculator on the market for remodel and new construction. Stair steps, rails, and balusters become a breeze.

★☆☆☆☆ Duane Fair · Apr 25, 2017

Too much permission request from this app. The calculator works fine. It doesn't need access to device and app history or call info, etc. Check the permissions yourself and decide if a calculator needs access to all that info

★☆☆☆☆ Billy Johnson · Dec 10, 2025

Been a brilliant app since I installed it 10 years ago, but for the last 3 months it's developed a bug. It takes forever to load, when it does it I do a calculation then come out of the app to use anywhere, then come back into this one without shutting it down then it crashes and weight accept any commands. Forcing an app closure then the long wait to get back in
