So far it seems like an extremely easy to use, simple app to do some complex calculations. Very intuitive. And so far, I get a pop up everytime I get an answer, but it is a simple "select no" type pop up so no waiting for an add to play. After using it for a couple of dozen calculations, I have nothing negative to say about it. And from a perfectionist that's high praise
I do alot of wood and metal working and I use geometry quite frequently. I'm bad at memorization and have all kinds of therom charts all over my work space and do these calculations long hand. NOT NO MORE!!!! I was doing a complex build and wanted something that could streamline production and found this. I LOVE THIS APP. All I have to do is input my numbers and everything is laid out for you and you will be hard pressed to find a shape this couldn't do. 🌟🌟🌟🌟🌟
Used to be great, been using it for years but the ads have only been increasing, now they are beyond excessive.
This was a great app. Just updated to the latest version, and now it won't work if it's offline. Very angry over this! I don't have access to data or wifi at work, so this app is now completely useless! I will delete it now and will have to find another app. If you have a version that works offline DO NOT UPDATE!!!! I give the new version ZERO stars!
very useful application, for beginners and engineers who calculate with geometrical applications and calculations but but it's make it very aggressive
app is unusable. shows ads and do nothing else. used to be essential but now every time I try to make any calculation unskipable and non clickable advertisement of some stoppid game pops up and only way to get rid of it is to close app so next time I open it I'm welcomed with same flupin add which renders app completely useless unless you need it to see icons of calculators that were available in good old times 😵💫😮😢
My main go to tool for lots of application. Would happily buy to free myself of trickster adds. It's very hard to find a cluster of every conceivable shape, angle, area, volume, mass etc answering app that's so intuitive, accurate and give you the formula's used. So educational as well. Thank you developer.
Simple , functional and does the job but It would be by far the best if you also add origins to some complicated formulas I mean explanation for where they came from . Besides , some may be beginners and not be able to follow it.
Amazing it's very wandrful and help me thanks 🙏👍what can I do that's qunick that's great and useful just a bit rarely thanks Google
Just too good an application. Operational wise is good, accuracy and the UI just perfect......alot of other theorems you may not use ...not becoz they won't give you the answer, but you might not need them at the moment... keep it up guys... keep improving..,. Good job. Thanks.
I don't want to see ads, why don't you have a purchase option to not see ads?!
Brilliant! As a guitar restorer who's not trained in mathematics, this app is a life saver! Saves me precious time trying to figure out geometric formulas to get precise measurements for a precise job. Beautifully laid out, intuitive and highly customizable UI with minimal full display ads. I wish dev would explain Mass and Density, and Split 2D/3D settings! Toggling these perimeters don't seem to make a difference! However only been using for 1 hour and I'm sure I will figure it out soon.
Incredibly easy to use. I love that it includes the formulas needed for calculation. The ads are fairly infrequent. I hesitantly knocked off one star because there is no way to pay to disable the ads.
Mostly nice. It would be more useful if the diagram of the shape would update to the actual dimensions of the numbers you enter - even if not perfectly to scale, a ballpark visual correlation would be nice. Thank you.

I'd give it 5 stars if it wasn't for the damn annoying ads. When I make the calculations I want to be swift. Not wait for nonsense. Not to mention the noise from the Ads that always disturbs either me or Anyone else around me. Please, gove us a paid version!
Got what wanted, brilliant app. All formulae are precisely described... Required more of your app:- 1) Orthocentre and altitudes. 2) More characteristics of Special Points Of A Triangle like a)Distance from vertices b)Distance from opposite side 3) Reverse calculation should also be available for example a) To find Area using Circumradius(R) and three(two) angles Make efforts and you can grow enough to get functioning without advertisements... Wish you well...
I've been trying to solve a trapezoid problem requiring a partial differential equation and this app solved it for me. Great work. Excellent 3d figure selection. My work also involves toroidal modeling, which I was surprised to find on your app. Thanks again.
This is a great app. For years I have been working on a problem/dream for a 3d object. In one 5 hr. night I was able to work thru the issue and found my answers using this app. I am no rocket scientist! I know there are people out there that could have stated the answers I was looking for within seconds of hearing my questions. I got to figure it out by myself with this app. Thanks Cck
Its an okay app. A bit tedious when it comes to getting answers with π since most people tend to use raw "3.14" instead of the all the numbers in the decimal, which it tends to change the answer by a lot. But it is being solid. Just wished there was a feauture that allows you to to toggle π as just 3.14 on it's formula. Other than that, pretty okay and gets the job done.
Super disruptive ads. Checking out the app, the first click stopped me for a 30 second ad. Checked two more and another 30 second ad. Now and then is fine, but such long ads so frequent is not workable.
