Best calculator


I work as a carpenter and I can tell you that this is hands down the best calculator when doing layouts and finish/framing work. Easy, fast, and great user interface. A bit pricey if you wanna remove the ads but I’ve used it every day for the past 3 months that I decided to actually buy it and contribute. Thanks for the product.

History tool


The history function allows me to go back and verify that all of my inputs were correct and check my work. For me this is very nice feature as I can make sure a typo does not mess up my project.

Very Useful App


I am a farmer and an engineer, and this app comes in really handy when working with my feet/inches stadia rod while topo surveying. You can mix and match decimal feet and inches with fractional feet and inches. Thanks to the developer for a nice program.
