Meet Maker Calc: The Tape Measure Companion. A measurement calculator for real-time fraction math on those tricky equations you need to perform while working on projects. Instead of using a normal calculator and suffering while you are constantly converting from decimals to the fractions on your tape measure, Maker Calc allows you to quickly input measurement-based fractions to calculate your results in real time as you type. Additionally, conversions to metric, feet and inches, and others are generated upon typing as well. One of the most powerful features is the ability to see rounding options based on your selected rounding precision. If your result falls between two measurements on the calculator, then below the screen, you will see the nearest fractions and be able to select the best one for your application. This empowers you as the builder to decide how precise you would like your results to be. About: My name is Jake Hasler. I’m a hobbyist woodworker, leatherworker, and maker of many things. I haven’t been able to find a great measurement calculator that I love, so I decided to build my own. My goal with Maker Calc is to put a tool in your hands that you can trust and that you enjoy using. I’ve put my heart and soul into this app I hope you love it as much as I do. Thanks for being here. - Jake PAYMENT INFORMATION Maker Calc has two recurring subscription plans available. A monthly offering which costs $1.99/month and a yearly offering which costs $19.99/year. There also exists a lifetime option, which is a one-time purchase of $49.99. Subscriptions can be managed through the app store after purchasing.
