One16
A fraction calculator designed for woodworkers and makers.
Widgets
Our phones are often doing double duty in the shop. Widgets allow you to view the latest answer easily on your lock screen or home screen so that you can get the information you need as quickly as possible without having to reopen the app.
Quick Toggle
One16 can easily convert decimals to fractions, and vise versa. Allowing for a wide range of flexibility in how you work.
Equation Builder
We are usually working with the same measurement several times. Quick Builder allows you to double tape any term in the history tape to quickly reuse, saving you the extra keystrokes.
Left-Handed Mode
Two variants of our calculator keyboard, one for right handed use and one for left handed. We have carefully thought about what buttons are most used, and placed them in easier-to-reach areas.
Native & Familiar
Inspired by the standard calculator making One16 instantly familiar.
Built for makers, by makers
Code Carton is a one man company. One16 was created out of frustration with the current fraction calculators that exists on the the Apple ecosystem. The features and design were influenced by what I needed in a app while in the workshop.
