Don’t waste your time unless you want to pay for an over-priced subscription

I had used the standalone calculator before and really liked it. When I saw ConstructionMasterProCalc I thought I would try it. Unfortunately, it would not let me run ConstructionMasterProCalc without choosing a subscription plan. Sure I could cancel in 7 days and not get charged - if I don’t forget. However, the price was so outrageous that I just deleted ConstructionMasterProCalc . 50 bucks for an annual SUBSCRIPTION is ridiculous! The calculator is good, so I might pay $30 or $40 to BUY ConstructionMasterProCalc , but I’m certainly going to pay forever for a subscription when you can buy the standalone calculator that will last for years for $50 or $60. Sorry I wasted my time.

YOU PAY NOW or WE HOLD YOUR DATA HOSTAGE.

I like having different types of calculators but paying 4.99 a month or 40 dollars a year? Seems steep for your average weekend warrior or hobbyist woodworker. They just updated it so I wanted to look around at the new features. The developers have a lock out screen now and are forcing you to pick one option for subscribing. That is just not cool and would hold your notes and data hostage if your subscription ran out. That is a deal breaker right there and needs to be fixed. Lastly, I have enough subscription based stuff and don’t need another one nickel and diming me. Give me a lifetime option please.

I wouldn’t reward this type of behavior.

Pretty Obvious Bait & Switch

While the description does mention that the first seven days are free and then there’s a few structure… it’s pretty deep into the description, and not many people looking for this type of thing are going to read that deep before downloading an app. What I found most off-putting was the snarky sarcastic tone of the developer’s replies to critical reviews. Whoever is writing the replies for this developer isn’t even bothering to hide their absolute disdain and disrespect of potential customers. If this is representative of the “customer service” experience, I’m glad I deleted ConstructionMasterProCalc without even starting the trial. Do yourself a favor, find a better app with actual customer service. Don’t pay $40 a year to be treated like a peasant for a run of the mill calculator app.

Subscription is a scam

I have the hand-held calculator and it’s awesome! Downloaded ConstructionMasterProCalc thinking it would be a simple purchase (and it used to be, I just didn’t act on it earlier), but now they’ve joined the subscription scam movement where you can’t just buy something and use it, you have to continue to pay them, basically renting the thing. It’s one thing to pay a subscription for an actual service but you shouldn’t have to pay for a subscription to use a product, you should be able to buy and not rent. My advice, buy the hand held one, it’s $75 on their web site, it’s great, don’t give in and pay way more to rent the thing on your phone.

Subscription? No thank you

Looks like the handheld and I’m sure there are much more sophisticated and user-friendly features in ConstructionMasterProCalc , but the price for ConstructionMasterProCalc if it’s subscription-based is absurd. I would probably purchase ConstructionMasterProCalc for $40-$60 if it were a one time purchase. But you’re talking about charging me over $200 for the time I’m going to use it. For that price, why would anyone choose ConstructionMasterProCalc over the handheld? Of course I’m biased but this change seems extremely unfair to the customer. I will choose another brand for my handheld based on this. Looking forward to the snarky, condescending response from the developer. Please do your worst. 🍿🍿

Was a good deal with app purchase till update

Was a great tool with a simple one time fee till the last update . Now I get the pleasure of having to login in to apple each time I use it cause they decided to make it a subscription . Sorry I’d use my real construction master over that any day of the week . I would like this fixed but I’m sure it’s gonna take a long time . I’ll use it till they will not let me , but I regret not waiting 24 hours on any updates. I paid for ConstructionMasterProCalc along time ago already.

Keep it simple

Please allow me to keep the calculator in full screen mode. I should not have to hit the full screen tab every time I open the calculator. I’m constantly hitting the home and help buttons by accident. I hear button clicks, but it doesn’t always register on the calculator. I’m having to redo calculations almost every time I use this calculator now. I’m also pretty sure there’s some glitches in the software calculations as well. These are all new problems in the last few months that I’ve never had in 30 years of using this calculator. This has always been a 5 star app, but not now.

It’s always with me

As a GC I have used a Construction Master almost daily for years. It’s the industry standard. The problem was I would use it at my desk while working on a bid and not have it in the field the next day, or reach for it in while pouring over a set of plans only to realize it was in my bags in the truck. Not anymore! My phone is always with me and now so is my Construction Master.

Great calculator

Have used my desktop model for 30 years and couldn’t live without it until ConstructionMasterProCalc. Although the giant desktop is great for crunching numbers at home I always use ConstructionMasterProCalc on the job site. A bit pricey but worth it if you want an in depth construction calculator and especially if you are already familiar with the format of the non virtual model. Have no regrets about buying.

Best Calc app for construction!

I love ConstructionMasterProCalc and use it every day in the job. It can do many things and has a help section to show you the proper way to figure for your project.

The only thing that annoys me about ConstructionMasterProCalc is that every time it updates it turns key clicks back on which I hate. I’m just turn them back off but at least save my settings. But still easiest 5 star rating ever

Recommendation

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 ConstructionMasterProCalc became available, download it in 2005 or 2006
I have had no issues with ConstructionMasterProCalc or the calculators that I own they work extremely well, however, and that is a big however, when I recommended ConstructionMasterProCalc 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 ConstructionMasterProCalc 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.

Excellent App

If you’re making a living in the trades, you need ConstructionMasterProCalc. Always with me because it’s on my phone, not a separate device that I could easily forget or leave somewhere by accident. I use ConstructionMasterProCalc nearly every day. I’m a residential builder/remodeler and this is a go to app for roof framing, layout, gable walls, stairs, concrete, blocks, and brick takeoffs just to name a few. I am always finding new ways to use ConstructionMasterProCalc. Highly recommended.

Best little calculator

I had purchased the stand alone calculator many years ago and ConstructionMasterProCalc at least 4 year’s ago. The calculator holder on my tool belt is a perfect fit for my phone. This is a great app as well as the stand alone. Best of all the help and manual is one click away if happen to forget the keystrokes for the stair layout or any other function. ConstructionMasterProCalc is similar in cost to the stand alone, but I would still own both. When I do not have phone in my tool belt the calculator is there. The new calculators have a tough plastic shell and the older version have an opening cover like a notebook. So I guess I own three. This is a great calculator layout for a builder.

This will help your career

I have had this on my iPhone for a very long time. Super convenient because you normally always have your phone on hand, not always a calculator when you need one in the field or shop. I have used this as a metal fabricator, structural fitter, ironworking in buildings, plants and working on large ships. ConstructionMasterProCalc is always updated with newer software which you cannot do with a calculator. If you use a calculator in the trades, just get ConstructionMasterProCalc.

Thank you

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 ConstructionMasterProCalc 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

Last of a dying breed

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. ConstructionMasterProCalc pays for itself.

GREAT Calculator!

I’m just a DIYer handyman, with some mechanical aptitudes. Although I’m not a professional, I love this calculator for my woodworking projects and home improvement/repair projects. It’s a whole lot easier than trying to figure the calculations out in my head.
I’ve had a physical version of this for years. But some of the improvements in ConstructionMasterProCalc are truly amazing.
Whether you’re a professional or, especially if you’re a DIYer like me, I would HIGHLY RECOMMEND that you add this tool to your toolbox!

Great value

Where do I start singing the praises for ConstructionMasterProCalc? Let’s start with the construction master calculator itself. It is an invaluable tool for figuring roofs alone, but so much more. When you have ConstructionMasterProCalc on your phone it is always handy and at your fingertips. I purchased ConstructionMasterProCalc many years ago, and it transfers every time I replace my iPhone. I probably would have worn out several calculators in the time I’ve had ConstructionMasterProCalc. Cool thing is, when there is an upgrade, it downloads and I am up to date in minutes. I cannot live without the Construction Master Pro. Just sayin.

Construction calculator

I found the original construction calculator at least 15 to 20 years ago. I have used them ever since that time, I have always had a couple in my truck one in the office one of my briefcase and several of them I have dropped broken over the years and had to replace. When I was looking to buy another new one I saw that they had ConstructionMasterProCalc online and now with it having it on my phone I have two on my desk there’s none in my truck there’s none in my briefcase it all works right off the phone and I haven’t broken it once. If you are in construction of any kind you should have ConstructionMasterProCalc on your phone.

Beware : Subscription

Be aware that ConstructionMasterProCalc has been changed to a subscription based model, rather than the outright purchase it used to be. The text description has not been changed to reflect that fact.

20 May 2023: Change log for new update is an ad for a different item. Wonder what they've taken from us this time.
