About Vandersoft

Vandersoft started in 2014 with a one rep max calculator, built because the existing ones were either wrong or buried under advertising. It grew into a catalog of apps covering weightlifting programs, running plans, CrossFit logging, 30 day challenges, nutrition and military fitness testing.

The through-line has not changed. Each app does one thing, holds the arithmetic so you do not have to, and gets out of the way while you train. None of them require an account to be useful, and none of them are trying to become a social network.

How we build

Three commitments run through everything we ship:

• Your data is yours. Where an app stores a training history, you can export it.
• It should work offline. Gyms have bad signal. An app that stops working in a basement is not a training tool.
• Say what the app does. If a program is not for beginners, we say so on the page rather than after you have downloaded it.

Who we are

Vandersoft is a small independent studio based in Seattle, founded by Charles Vanderhoff, who holds a BS in Computer Software Systems from the University of Washington.
