Comments on Construction Master Pro Calc for Android

★★★★★ Jose Cadena · Jun 13, 2026

It's a really helpful tool I use it on every project framing, siding, roofing, concrete, bidding jobs

★★★★★ Tele Bruce · Jan 13, 2026

Every tradesman should know this app inside and out. It's a real lifesaver. I have used handheld calculator for more than 20 years. I wouldn't be without it. And the app has more features.

★★★★★ Brian Combs · Aug 2, 2026

I've had either this or the physical calculator for 25 or more years. Hard to imagine life without it in the construction world, pre AI. Even as AI gets better, this calculator holds its own.

★★☆☆☆ Z C · May 18, 2026

This was once a good option, but it's no longer available for a one-time payment. Now they make you pay a subscription fee which to me is not worth it when I can just Buy the fiscal calculator

★☆☆☆☆ Esus Ang · May 6, 2026

Paid full price for its years back. Came back to see now it's based on subscription. Do what of my original money?

★☆☆☆☆ Bernie Morris · Aug 5, 2026

Pay monthly or annually. No one time purchase. Others exist that work for what I need, but I don't have to pay $5/month or $40/yr.
