I made the purchase which also promised to remove the ads. It unlocked the calculator and removed the small banner ad at the bottom. However, it did not remove the annoying pop-up video ads which seem to pop up about every 3rd calculation and you must wait several seconds before closing them. If you're going to pay for a calculator of this type just buy one without ads. I wasted $1.99. ### 2/5 — Read this before buy! *2016-06-15* App it self is not bad except, it have very little things to do, but it's okay, but what I hate this this app makers for? Right after I've installed this app, very first try, free version, as soon as I opened up, message pop out, (upgrade this app and remove adds), and option {Cancel or Okay} so who would like to be interrupted in the middle of estimate progress, if you hit cancel, it will cancel, and you won't use app, of course I hit "Okay" after couple seconds of upgrading, and of course upgrade is $1.99 first thing app did, it CRASHES!!!!!!!!! YEAH!!! CRASHES!!!. So I did restart app again, start my building material estimate, as soon as I typed up numbers and hit = button, instead of giving me result Dumb ADD POP OUT!!! Yeah ADD!!. And after paying 2 bucks and having adds with crashes, on my app?! That's why I hate this thing. But science I've paid 2 dollars I'll keep this for a while. ### 1/5 — Does not work... *2016-01-28, version 2.1* Useless!! ### 1/5 — Not so good *2015-08-24* This thing is not what you want. Carpenter's Helper Lite is much better, the only reason I tried this one, was that the Carpenters Helper is no available for iPad. This one only has 3 things you can do, stairs, equal space, and a regular calculator. Also has a lot of ads, I deleted it almost immediately. ### 1/5 — Garbage *2015-08-03* Crashes every time I try to use ### 1/5 — Rubbish *2015-07-28, version 2.1* Downloaded this app and upgraded it to remove ads, the ads still pop up during the use of the app which is highly irritating, can't review the ap due to the constant pop up of ads . ### 1/5 — Crap *2015-03-28* I give it a one star because they make you. It says it is free and will do all of this stuff. But it only gives you a few of the things it will do. For the others you have to pay. So the app is not free. And is miss leading. ### 1/5 — First thing I saw was a full-page ad. Another advertisement factory. *2014-12-11* I downloaded the Calculator opened up and a fullscreen and came on. I promptly deleted the app and never got around to the calculator part. Developer has no skills and should be ashamed of himself. Other reviews feel very fake. ### 1/5 — Useless fre version *2014-12-10* It freezes up and is very slow to respond. Ads are thown in with every try of the features. Calculator uselss as it does not handle fractions. Too specific. Very bad job with free ver if trying to entice for purhcase. ### 3/5 — Quite good *2014-10-27, version 2.0* Very useful app for site managers and builders. Makes it very easy! ### 1/5 — no good *2014-09-02, version 1.1* waste ur time if download ### 3/5 — Good App *2014-05-19* Good App but not great, I would like an updated design that is easier for big fingers and also not have to pay for added features. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not great! *2018-12-05, version 2.1* Paid to remove the adds & you still get them!!! Only works in ft & inches NOT metric!! Waste of £1.99 ### 1/5 — Complete con! *2018-10-10, version 2.1* Waste of time as the app does nothing other than try to sell you a more advanced version or link you to websites to spend money. Apple should not allow this kind of rubbish in their App Store! ### 1/5 — Doesn’t work properly! *2018-09-14, version 2.1* I’ve upgraded but the Slab feature doesn’t work, every time you try and put the depth measurement in the answer box disappears, also it closes down when ever it feels like it and the upgrade doesn’t get rid of the annoying pop-up ads... please fix these bugs otherwise it shouldn’t be in the App Store, one has to wonder if Apple checks the apps before they sell them!???? ### 1/5 — Junk *2018-05-04, version 2.1* Paid $3 to get the adds to stop, and open the other calculators, I still get adds and the calculator give you such large fractions, I don’t even know what they are. For example it gave me 66’5-333/500” What the heck is 333/500” of an inch ### 1/5 — Do not buy! *2017-04-30* Purchased this app to calculate if a frame is square. The results are not understandable. ### 1/5 — Nul *2016-10-03, version 2.1* Nul ### 1/5 — Free? *2016-09-04* The only thing free about this app is the download. ### 1/5 — Another con!! *2016-08-27, version 2.1* This app looked really handy but i cant be doing with the pop ups!...so payed the £1.49!...waste of time! still get adverts!!...don't false advertise!!...are you that hard up for cash you need to lie about £1.49??...give us buyers a break please! Apart from that, app has some useful calculators but if you don't like the adds don't waste your money!!! ### 1/5 — Not worth downloading *2016-08-20* The app froze up on first use. When I opened it back up I realized you couldn't use over half the features. The features you could use caused the app to crash. So, question, why buy it if the free version doesn't work? ### 1/5 — Déçu *2016-04-07, version 2.1* J'ai payé pour avoir cette application sans publicité et j'ai toujours des pop up. ## Most praised reviews (10 highest-rated) ### 5/5 — Super useful app!!! *2015-08-03* This app has great tools for working, unit conversions, calculator, stairs calculations and more, with the pro version you get even more, it's worth it ### 5/5 — Become more useful *2015-07-31* This updated version becomes more useful and errorless. Awesome. Thanks for update. ### 5/5 — Most Useful App *2015-07-27* I like this app for fast calculation in constroction work. I use it daily and working perfectly! ### 5/5 — Nice calculator *2015-07-25* Great calculator it helps me in my work ### 5/5 — Great for contractors *2014-11-01, version 2.0* Great app for determining measurements! ### 5/5 — Great building app *2014-10-25, version 2.0* Very handy for all building and construction calculations. Highly recommended. ### 5/5 — Help for for the DIY *2014-05-19* This app saves time scribbling on paper and drawing out when you need to redo a fence or other around the house projects. Helpful. Haven't used the concrete calculator. ### 5/5 — A must! *2014-05-17, version 1.1* I have my own building company and think this is a great tool to have. One issue which would make it better, to include options for other formats eg. Metric to cater for everyones uses. A definite keeper. ### 5/5 — Great tool in my pocket *2014-05-15* Nice design and plenty of options to help with advanced calculations that would take a number of different tools to figure out. ### 5/5 — Awesome *2014-05-12* Feeling excellent playing this one. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
