Built in public, by two people who lift.

TempoDisc is a Danish-founded hobby project with serious intent. Thomas Vagalis and Martin Juul are building a simple training tool: a magnetic disc that tells you, at a glance, whether you lowered the weight on tempo.

We are not a lab, and we are not a big sports-science company. We are building in public, testing the idea with lifters who care about controlled lowering and hypertrophy, and only going further if it is actually useful in the gym.

Who we are

Thomas Vagalis looks after the product and the business side, from Portugal.

Martin Juul is building the first prototype — a student working on this as a focused side project.

What we believe

Most tempo and velocity tools cost hundreds of euros and ask you to live in an app. We think the cue should live on the bar, take seconds to set up, and cost less than a coaching session.
