The coach we would have
needed ourselves.
paceos was born from a simple frustration: every running app shows you data. None tells you what to do with it today. We build the app that turns your numbers into a real decision every morning.
Who is behind paceos? paceos is developed by Daniel Schwarz in Frechen near Cologne, Germany, and has been on the App Store since September 2026. Sven Falkenberg is responsible for marketing and community. The app grew out of our own training with Garmin and Apple Watch and is developed daily with a small circle of experienced runners.

The body leads
A plan that ignores sleep, HRV and recovery is a plan for a runner who does not exist. Yours adapts. Not you to it.
No black box
Every recommendation is based on established sports science and explained to you in two sentences. You should understand, not just obey.
Your data, only for your training
Health data is processed exclusively for your training features, stored encrypted, never sold and never used for advertising. There is no ad tracking. Exactly what goes where is in the privacy policy.
Built on science,
not on gut feeling.
Behind every metric is an established model of training physiology. We do not invent formulas, we apply the right ones consistently to your data.
Banister · impulse-response
Chronic and acute load, fitness, fatigue and form as a trend.
Seiler · polarised training
Lots of easy, little hard. paceos notices when your easy runs are too fast.
Daniels · VDOT
Pace zones and threshold pace from real runs, updated after every race.
Two runners, one app.
Daniel Schwarz
Passionate gadget lover and self-taught developer: even as a child, Daniel took things apart, thought them through and turned them into code. paceos is the sum of that obsession. The technology deep inside vital data, models and machine learning, with the eye of a runner who wants to know what his numbers really mean.
"I trained with data for years and still often felt in the dark. paceos closes that gap: a coach who reads the signals we all already wear on our wrist."
Sven Falkenberg
A close friend and passionate endurance athlete: Tough Mudder world champion, finisher of major marathons around the globe, even across the desert. For years he has lived the training that paceos maps digitally, and he brings exactly the runner's perspective that makes a coaching app real.
Sven is responsible for everything paceos shows to the outside world: marketing, PR and community. As the link between sport and app, he gives the brand its voice.
