Spotter

A tiny gym coach for a few friends who lift together. It knows what to lift today and what you lifted last time, and it keeps the crew showing up.

Spotter tells you what to do at the gym right now: which machine, which weight, and what you lifted last time. Friends train together in person or virtually, each at their own time, and the crew board compares who showed up, never who lifts more.

Why it exists

The plan was never my problem. Showing up was. So I built the app that removes every excuse I had, with Claude Code as lead developer and a small team of agents doing the typing. The whole story is here.

It’s free, private and invite-only, for me and a few close friends. Inspired by Jeff Nippard’s minimal, evidence-based training style, and not affiliated with or endorsed by him.
