Geometry also has many practical uses in everyday life, engineering or a construction: such as measuring circumference, area and volume. Ideal when you need to build or create something. For example, you must calculate the perimeter of your yard to determine how much fencing you need or calculate the surface area of your walls to determine how much paint you need.

Helps with very easy formulas and gives the correct answer. It’s very easy to understand and gives you the answers. But it’s missing a few things. It doesn’t simply give the volume of 3d shapes and is missing the all triangle pyramid (a pyramid with a triangle base). Other than that, it’s amazing and works very well.

Developer Response ,

Hi, I'm not sure what you mean that it doesn't calculate the volume. Every 3D shape has also volume calculation included. As for the "missing" triangle pyramid, if you open up the "regular based pyramid" shape - there's a "n" - parameter which determines how many edges the base of the pyramid has. So if you want a triangular base, just set "n = 3". Send me an email from application and I can explain in more detail.

Nice, but not worth it.

Calculate surface area and volume great. But not worth buying!! You have to set what style of measurement you are using meaning, standard or metric. After you have set that in settings, you cannot switch it to convert something that you have done. Also, when converting the volume of material to the quantity of it, meaning how many gallons are to a cubic foot. It’s in centimeter mode, and cannot be changed, so defeats the purpose. It’s not fun running back-and-forth to Settings, converting the measurements for metric to standard for surface area and volume. Worse than that is when you have to get another app to convert one cubic centimeter to one cubic foot or any other form of measurement. An example is one cubic foot is how many cubic centimeters. It will tell water to cubic centimeter ONLY same goes for all of the surface area and cubicvolume. Only because of my knowledge one cubic foot is 7.4 gallons. If you need the formulas for cubic area or surface area works great. But get ready to go into settings and changing from metric to standard whenever is needed to. You also have to do that before you enter your numbers to solve the geometry if you don’t, you have to trash the first calculation, then do the calculation over!

Hello and thank you for writing a review. I must admit this use case of converting units on the fly is an interesting idea and I'll think about how to implement it in the app... At the moment there are 5 fixed units that can be switched when calculating volume, but surely they could be expanded. Expect an update in the near future 😉

Well designed and priced

I can and have done most of these formulas with a calculator over my career but I don’t have to these days. I looked through a bunch of these apps and most were either poorly designed, dysfunctional in some way, or overly priced. And I’m sick and tired of everything being a subscription nowadays!
This app is well organized, professional in its appearance and functionality. It’s also priced accordingly for something “I” will only use occasionally. I made a few formula calculations the old fashion way and checked them with the app. They matched as I expected and I paid fir the app...Once!!!

Developer Response ,

Thank you for the awesome review. I'm really glad you like the app and chose it among the others. Formulas and shapes will be added over time, so your purchase should be well returned over time. And let me tell you a secret - I personally also despise subscriptions (from a user's perspective of course) ;)
