worth buying if your in the trades, I have both the physical calculator and the app. I'm in maintenance now (was in construction when I bought this) and still use it regularly to do math in feet/inches and convert from metric to imperial quickly and easily. works very well as it is! I wouldn't recommend this to the average joe however, as it doesn't provide much bonus function beyond converting from metric to imperial in measurements of length and weight. (for the average joe.)

I like the app, but!!!! I find the app appealing, however, I am terminating my trial subscription. I would be comfortable with a one-time fee for the subscription, but not an annual renewal fee. I possess the physical construction master pro calculator. I find the convenience of its availability on the phone to be appealing, especially in the event I do not have access to a physical calculator.

A price of $45 would be a tall order as a one-time purchase price for a couple of well-known math formulae; as a recurring annual subscription fee, such a level of greed is simply ridiculous. Given that there is no shortage of alternatives both on Android and the PC, some of them with more functions and features, it does not make sense to allow oneself to be bled dry in such an outrageous manner. Consequently, this milkingware has been replaced with a better alternative and uninstalled.

It's been fine for a long, but now I'm locked out of a paid pro subscription, and I have to go the the most labyrinthine f_ing process to dig up purchase information from 8 years ago, only to find that it didn't work. Wouldn't it just suffice to sign into my Google account from which I made the purchase??? Edit: got it solved, developers are responsive. Still not pleased about the reactivation hassle, but I was too hasty to review.

Great product. Love it. But not paying $50+ canadian per year for a subscription Buy buildcalc instead. Basciacally the same but 1 time payment Maybe there should be a lite version. Mainly use the adding of dimensions and volume of concrete and stairs There is a lot of great things on the calculator but I'm sure most people don't use all the functions

I was able to get my registration issue resolved. I do have an issue with the way Google handles transactions made over 7 years ago, you have to scroll through the list of purchases and there's no way to search for transactions. Which made the process very long and tedious. Nothing against the developer of the program. The program itself works fine and I've used it for a long time. So my issue is with Google more than with the app so my apologies, I regraded the app to more positive review.

Trying to get this re installed. Either they were hacked or the management has lost their minds. This was my dailey go to and a valuable tool for me. But recently they changed from a one time purchase, to a monthly/yearly subscription. The app will not open and tech is requiring proof of purchase from many years ago. Very unprofessional! I would steer clear until they figure it out. One star because zero is not an option.

When I purchased this app back in 2014 I gave it 5 stars. When I went to use it recently I had to try and enter my purchase details which I did without any success. I am not paying a subscription. I will purchase a physical construction calculator for a few bucks more than the annual subscription. Happy to buy a calculator but not happy to pay a subscription to use a calculator.
