Construction Master 5

I was hesitant to get this app but I'm glad I did. It is just like the $60 calculator you buy only you have a settings and preferences menu and you can take screenshots of your calculations instead of having to write it all down on a block of wood

Great app. Started with the old school calculator like 20+ years ago in my construction management position and got this app when apps where born on cell phones and still use this everyday. If you in any kind of construction, you need to get this app. It's way smarter than me for sure!!! You can't live without it after you start using it. Seriously!

I've been using this app a long time. It's exactly the same as the calculators our company uses and I never misplace it now. Perfect for home renovations and an all in one calculator for every day use! Well worth the cost and I have always been able to reinstall with new phones.

Great help. I'm an amateur trying to do a hip roof on an outbuilding. The instructions and functionality made the calculations super easy and accurate. Thought about buying an actual calculator but decided on this instead. Glad I went with the app!

I have used this app for years in home design and could not be happier. It's on my phone and tablet and I use it daily. I have easily downloaded to new phones over the years.

Wonderful calculator. I use the physical version daily at work and it's so nice to not have to spend an additional $40 to get the same functionality at home.

I have being a contractor for about 30 years had a few of the CM5 calculator, but now with the APP on my phone it makes life in the field much easier. The app is great, flawless, I love and strongly recommend.

I purchased this app today but it is not accurate!!! It gives me a different answer than my physical construction calculator!!! Example: 11'5" run and 7 pitch Physical calculator gives me answer of 13' 2-5/8" diagonal Your app gives me 11'6" diagonal I want a full refund immediately because this is unacceptable!!!!!

well I reset my review from 3 stars to 5 thanks to the help I recieced in my last post. so if any user needs to go to a 64th of an inch. go to settings and preferences. then click the 1/64th of an inch setting. luckily I can now figure out what I need today!! THANKS FOR THIS AWESOME APP!!!!

Unquestionably the "Gold Standard" for any builder, contractor, or estimator. Absolutely indispensable for both calculations on the job site or for estimating back at the office. Can't wait for the model that will even order materials as well as call the subcontractors to find out why they are late for the job.

Have been using construction master calculaters since 1993 when I purchased a CM3 with trig. The app was a great add very pleased with the product. Very satisfied customer.

Been using this app for many years it's great to have it on the phone and take it with you to the next phone breaking the hardware in construction is not such a big deal

Use everyday. Used to use complicated formulas laying out pool cages. Now I can't let them see how easy it is

I thought this app was good but I got an IPhone now and I can’t use it I had a android phone and it won’t work on my iPhone so now it’s a waste of my money. 😒

Love the company and have for years they have always stood by their product and so do I their calculators make life alot easier for Craftsman Carpenter welders Fitters plumbers anybody that is building anything Need 10 star or a goldstar for them top knoch

Love the app but you better not break your phone bc they will make you purchase the app again! This is my 3rd time to purchase this app!

Perfect thank you!! Use this for squaring house footings and walls, works great!!

Cheaper and better then buying the actual calculator. Works great!!

Never will I use a different calculator. Has everything I need for carpentry.

Useful for the job and convenient when needed.

Need to have more carácter for larger computation, the rest is excellent

Absolutely the most amazing at 5 ever used as far as a construction tool highly recommended
