edit: this is an amazing app. On the concrete volume calculations you just have to watch how you're entering L1/L2 and W1/W2 for complex shapes. It's worth paying for and far beats out the rest that want subscription plans. I've been using it to build a large addition, deck, and other projects this year. it's indispensable.

Hi Vlad - thanks for the updated review! I'll see what I can do to improve the UI for that input - I agree it takes a bit of extra focus! Feel free to reach out at WinogradApps@gmail.com if you ever have any other feedback or questions. Thanks!

This is a great app for anything related to construction, architecture, woodworking, etc. It allows you to jump from different units such as cm or mm and easily add them and see the results in the units of your choice (imperial or metric) The triangle and circle tools are great time savers. Still works on this old android phone.

I really like this app and have found it very useful. I wish there was a "center" button or function that would automatically tell you the center of the dimension you have entered

Thanks for the review and feedback. You have a couple options for getting the center. 1) divide by 2. 2) tap either the input or output line, then press the /2 button to cut the value in half. Feel free to email me at WinogradApps@gmail.com to discuss further!
