tensr.fitness

tensr is agent-native, and open by construction.

Your training data is a SQLite file on your device and your routines are plainworkout.md. Nothing here is locked behind an export tax. These docs exist so you — and the tools and agents you control — can read, write, and build on your own data.

workout.md spec →

The routine format: human-readable, machine-readable, printable, and useful by itself.

Data model →

The SQLite tables your export contains, and how to query your own history.

Link format →

How a shared session or routine rides entirely in a URL fragment — no server.

Agent skills →

Teach your own model (Qwen, Kimi, MiniMax, Claude…) to coach you from your data.

Why open

Holding data is the cheap part; storage is pennies. The value is in actingon it — and in the agent era, an assistant is only as good as the data it can reach. So tensr keeps the canonical copy on your device, in formats any tool can read, and treats agent access as the default posture rather than a paid tier.

If you build something that reads tensr data — a coach, a visualizer, an importer — we want to hear about it. That's the point of publishing these.

The one principle

Boring Tech, Modern Fitness.
Fostering Data Ownership.
& Social Accountability.

When you own your data, applications treat you with dignity — because you don't really need them anymore. So everything after install isopt-in.
