Comments on Construction Master Pro Calc for Android

★★★★★ Louie X · Oct 19, 2026
As a 20yr+ Senior Truss Designer, Construction Master has been there every step of the way. If you plan on building a house, you'll need the app or calculator first. It's a mandatory tool to have in construction. Great app, no complaints.
★★★★☆ Daniel Garcia · Jul 23, 2026
The app is great I have the physical calculator and on my I phone, but I have an android phone now but paying $40 every year is a robbery
★★★★☆ Jorge A. Moreno · Jul 9, 2026
I am very surprised I have been promoting this app for many years. We just hired 3 engineers, I told them about this app. To my surprised now they charged a subscription, when I bought it manuy oons ago it was a one time purchase. Engineers bought another calculator that is a one time purchase. Lost 3 customers last week. No longer promoting it.
★★★★★ Richard Reyes · Jul 8, 2026
It's a very helpful tool to have especially in construction and to help with measurements.
★☆☆☆☆ Budd Grissom · Apr 30, 2026
Bought this ap in 2016. Have used it for years, now I am locked out bc of an update. Not paying for a yearly subscription when I've already bought it outright. Not worth a subscription just for the ease of it on my phone. Just busting out my old handheld.
★☆☆☆☆ Alberto Salas · Jul 20, 2026
Been using this app for years, but since they moved to a subscription based I've been paying and paying, what happened to the one time purchase? It's a calculator bro not a Netflix account 😕
★☆☆☆☆ Matt Borgardt · Aug 22, 2026
You people completely insane $30 a year when I can buy the calculator outright... you are not adding anything new at all and there is zero a reason to pay a yearly subscription for a calculator.
