App Description

Woodworking is fun. Math isn't. Making the most of our precious time in the shop is critical. One16 can help. One16 was designed to respect your time, reduce errors, and make the mundane math operations less painful.

Introducing Actions.
Automate common calculations into fast actions. One of our favorites is calculating board feet. We ship One16 with a few to get you started. But creating your own is where the power of Actions shines.

The next time saver are widgets. Designed with glanceability at their core. They give you quick references to your critical measurements without unlocking your phone or opening the app.

We reference the same value multiple times. But not for related steps. Equation Builder saves you time by quickly reusing previous values. Double tap a previous value to copy it to your active term.

Privacy is at the core of all our products. One16 doesn't track any data about you or your usage. If you do find a bug, please reach out to us! We will do our best to get it fixed in a timely manner. We love chatting with our users!
