You are not actually allowed to use the free trial unless you commit to a month by month subscription or a yearly subscription. Obviously, they are hoping that you will forget after the seven days and just begin to charge you. What’s the use in a free trial if you can’t actually use it without committing to subscriptions. I don’t want to have to go in and cancel subscriptions just to try out the application.

I’ve used this app for about 4 years and have loved it. I went to download it for my lead man and I was very disappointed to see that they have a yearly subscription now. The price is ridiculous!

This is a ripoff that we have to pay a monthly fee to use the calculator on iPhones I buy this same calculator in my android phone and I switch to an iPhone and now they want me to pay a monthly fee when I already purchased the app is no fear to the people that already buy the calculator on others platform and it should be an option to buy the app outright and don’t have a monthly of yearly subscription like on android phones

I’ve been using this calculator for well over 20 years now. As a young man starting out in the trades, it was a big investment to buy $70 to have on the site, but I did it. As soon as the app became available, download it in 2005 or 2006 I have had no issues with the app or the calculators that I own they work extremely well, however, and that is a big however, when I recommended this app to my new hires, they told me it cost $20 a month. Since it’s clear people involved with calculators know how math works equivalent cost of this app over the next 16 years would be $3840!!! There is no way in good conscience that I can recommend this to any young man starting out in the trades. Any calculator can do this math for you. It just not worth it.

Have used the calculator app for over 12 years. Had a handheld model in our job trailer (right next to the rafter table book) when I began framing 30 years ago. It has made figuring stairs and roofs quicker and more accurate. With the programmed tolerances I can jump from commercial to residential stairs with ease. Checking work on stepped out rafters keeps everything square, level and plumb. From rafter jacks to yds of concrete in a footing. This app pays for itself.

This is the absolute must have calculator that you have to have if you’re gonna do anything and construction, I’ve had the Calculator around the shop for years. That we have used and still use to this day. When my boss told me about the app and made me get it. That was the thing in the world, complete game changer! I use everyday in every aspect imaginable. I want to say thank you master pro calculator for having the best thing since sliced bread! Y’all are amazing

Super convenient and works great.

The calculator works good, but in no world would I nor should anyone pay a yearly subscription for one. Without a subscription it would be awesome. Please change.

When you’re on the job, you must calculate exactly where your plumbing finishes must go. It’s a beautiful thing.

It’s a must have tool
