Wir sind Daten-Nerds, die gerne schwitzen

Wir glauben, dass jeder Herzschlag eine Geschichte erzählt, jeder Schritt Bedeutung hat und jedes Training wissenschaftliche Analyse verdient.

Unsere Besessenheit

  • Wir messen alles, weil Zahlen nicht lügen
  • Wir analysieren unsere eigenen Trainings seit über 10 Jahren
  • Wir haben das gebaut, weil bestehende Apps nicht nerdig genug waren

Built by Athletes

Every algorithm tested on real workouts, every metric validated through our own training.

Science First

No magic algorithms. Just peer-reviewed research, proven methodologies, and transparent calculations.

Unsere Mission

  • Professionelle Sportwissenschaft in jedermanns Tasche bringen
  • Daten zugänglich machen, ohne die Privatsphäre zu gefährden
  • Dir helfen, deinen Körper durch Zahlen zu verstehen

Unser Versprechen

  • Kein Marketing-Geschwätz - nur reine Daten
  • Offene Formate - deine Daten gehören immer dir
  • Ständige Verbesserung basierend auf neuester Forschung

Your Data, Your Rules

We can't access your data because we designed it that way. Privacy by architecture, not by policy.

Why We Built This

We tried every analytics platform out there. They were either too simple (just basic stats) or too opaque (magic AI scores with no explanation). And every single one wanted to upload our training data to their servers.

As data nerds, we wanted the formulas. As athletes, we wanted actionable insights. As privacy advocates, we wanted local-only processing.

So we built what we couldn't find: Apps that show the science, explain the calculations, and respect your privacy.

If you're the kind of person who wants to know why your VO₂max is 52, how TSS is calculated, and where the training zone formulas come from—welcome home.
