I REFUSE! -- Sashamouk, 2025-01-07 ### ***** "Game Changer!" This app has been a game changer. I don’t even know how many years I’ve had this app. In previous years before I got the app. I had the actual calculator that was very expensive . They got dropped , or were dropped upon and the job basically came to a standstill . I make sure the main guys on our site have this app, and would recommend it to anybody in the construction industry. -- Old Dude lol, 2025-01-04 ### ***** "Simple" Good calculator for this guy. Had it for over 12 years. Don’t go into the weeds with the calculator but promote to all our employees. Shame they charge an annual subscription now. -- Moiser76, 2024-12-17 ### *---- "sadly" Trusted and supported you guys for years, sad to see you switch your model to taking advantage of guys in our industry. To anyone thinking of subscribing, you can get a physical version of this calculator on Amazon or your local hardware store for a one time, fraction of the price purchase. Shame on you guys -- JjjjTqgab, 2024-12-08 ### *---- "Subscription needed" Subscription needed, no free version. -- FrankSau71, 2024-10-23 ### *---- "This is ridiculous and fraudulent" As a third generation carpenter, I trusted the ConstructionMaster name, but this is ridiculous. I paid for this app and now it’s running ads on me. I could understand if there was some need for a new edition and I chose to ridiculously buy it/subscribe, or even if there was a need for updates, but it’s the same functionality as the calculator I’ve had for 20 years. Good to know that if they could put microtransactions and ads on my physical calculator that they would. Utter garbage behaviour from a once reputable company. Zero stars isn’t an option. -- nichosx, 2024-09-05 ### *---- "Construction master pro app" I downloaded this app to try the 7 day free trial. Once I downloaded the app it shows you all the features of the app and then all you can do is choose one of the two subscriptions payment options. I can not comprehend why this app would be a subscription base app. Why wouldn’t I just buy their hand held calculator then. Make this app a one time payment and you will have less people upset with you. All your reviews all mentioning this. Let me know when you remove you subscription and goto one time purchase. -- It's 5 Oclock somewhere, 2024-06-22 ### ***** "Zero audio in demo videos" I turned off Bluetooth and made sure my audio worked on other apps yet no audio on the demo vids played through the app. And yes I toggled to onscreen mute button too. Solid app otherwise, insane amount of features -- Valmshmet, 2024-06-05 ### *---- "Theft" Robbing the costumer 60$ a year -- Jona7793, 2024-05-27 ### ***** "Subscription based app" Clearly this one the best calculators out there but I bought mine years ago. I have new apprentices on the crew that I wanted to all use the same calculator and I suggested this one. I opened up the app and to my shock and dismay saw that it was now subscription based! Which is an immediate turn off for anyone interested. Who wants to pay 50$ a year perpetually for a calculator?? -- Glassgas, 2024-05-09 ### *---- "Overcharged" Was double charged for app. -- GHDJgffghhh, 2024-05-03 ### *---- "Now Subscription? Pffft that’s sad" I bought this app before this new subscription system but a few of my work colleagues have shown me if they want the app they have to pay a yearly fee of $50? What a joke you should be ashamed of yourselves. It’s a god damn calculator. Kick rocks. -- A screaming Midget, 2024-01-15 ### **--- "Stop interruption" Like the app. But the beef I have it’s the interruption when I open the app (survey, updates, messages etc). When I open the app is to calculate now. -- CalculatorOnAHurry, 2024-01-14 ### ***** "For pro" It’s a great tool for calculate everything in job site -- cobradorcan, 2024-01-12 ### ***** "Best calc app for construction" Best calc app for construction. Extremely useful in Canada, BC. Here we still use both systems metric and imperial unfortunately. The app helps switching between the systems. -- Fungiblop, 2023-11-29 ### **--- "Update ruined performance" Ever since the update, the responsiveness of the keys on the calculator are no where near what they used to be. I used to be able speed through equations. Now, I have to retype almost every other calculation… -- JaymzL88, 2023-11-27 ### *---- "Not worth it." Should be able to do one time purchase and own it. Paying $60 annually for a calculator what a joke. -- Swaggerjaggger, 2023-11-14 ### *---- "Gouging" I don’t suppose there’s any recourse for someone who owned this app for several years in a previous OS and now is expected to pay 3x the original cost for an annual subscription ? Nothing but greed. -- Ol’ Floyd, 2023-10-20 ### *---- "Micro transactions.." Another great app lost to the world of corporate greed. App is fine, subscriptions are trash, and it’s disappointing that you can’t buy anything outright anymore. Go to HomeDepot and buy the physical product for $80 instead of being buckled and dimed forever. -- Jaypr, 2023-10-18 [View all Construction Master Pro Calc reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Construction Master Pro Calc In-App Purchases | Item | Price | |------|-------| | 1 Month Full Access | $4.99 | | 1 Year Full Access | $49.99 | | 6 Months Full Access | $24.99 | ## Construction Master Pro Calc Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Grossing | Canada | Utilities | #29 | | Top Grossing | United States | Utilities | #44 | | Top Free | United States | Utilities | #479 | ## Construction Master Pro Calc Discovered Keywords -
