Wij zijn data-nerds die graag zweten

Wij geloven dat elke hartslag een verhaal vertelt, elke stap betekenis heeft, en elke training wetenschappelijke analyse verdient.

Onze obsessie

  • We meten alles omdat cijfers niet liegen
  • We analyseren onze eigen trainingen al meer dan 10 jaar
  • We bouwden dit omdat bestaande apps niet nerdy genoeg 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.

Onze missie

  • Professionele sportwetenschap in ieders zak brengen
  • Data toegankelijk maken zonder privacy te compromitteren
  • Je helpen je lichaam te begrijpen door cijfers

Onze belofte

  • Geen marketingpraat - alleen pure data
  • Open formaten - je data is altijd van jou
  • Constante verbetering gebaseerd op het nieuwste onderzoek

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.
