Running Analytics

Your running data. Finally understood.

The data is yours. The answers are Runnerd’s. Readiness, form curve and running economy. From Apple Health, for every run you have ever done.

No subscription. No account. No compromises.

The gap

What Apple Health doesn’t tell you. Runnerd does.

Apple Health knows that you ran. Runnerd knows what the run did to you. And what that means for tomorrow. What your Health data holds.

Apple Health shows you
  • Distance and duration
  • Average pace
  • Heart rate as a curve
  • Calories and elevation
  • One run after another
Runnerd turns that into
  • Readiness score How much load you can take today, from HRV, resting HR, sleep and TSB.
  • Form, not a snapshot Fitness, fatigue and form across years (CTL, ATL, TSB).
  • Running economy Running power, aerobic efficiency, intensity mix (80/20), TRIMP.
  • A plan up to race day Season timeline with phases, weekly volume and race goals.
  • Context, not numbers Every run automatically typed and placed in your history.

Runnerd records nothing. It reads what is already in Apple Health. Runnerd turns it into training insight.

The difference

Finally on the Mac, too.

Serious running analysis has lived almost exclusively on the phone. Runnerd is a real native Mac app, not an iPhone app passed through. Years of training at a glance, with room for charts, splits and long trends.

  • Native macOS app, built for the big screen
  • One purchase, both devices · universal app for iPhone and Mac
  • Sync exclusively via your private iCloud, no Runnerd server

Runnerd knows what kind of run that was.

Every run is classified automatically, by effort curve, heart rate profile and pace distribution. You tag nothing.

Easy
Low effort, aerobic base. 70–75% HRmax. Actively recovers, builds foundation.
Long Run
Long, continuous rise. Endurance profile with drift. Foundation for all race distances.
Tempo
Fast rise, high plateau. Lactate threshold. Uncomfortable — and necessary.
Interval
Repeated peaks. Maximum intensity, deliberate rest. VO2max training.
Recovery
Flat, low, deliberately slow. Not training — active recovery. Just as important.
Fartlek
Irregular waves. Spontaneous intensity changes. Playful — but demanding.
Progression
Steadily rising. Controlled build from easy to tempo pace. Mental strength.
Race
Build with finish kick. Maximum effort at the end. All cards on the table.
Methods

No AI.
Real models.

Runnerd calculates with methods from training science, not from marketing. Every value has a name, a formula and an origin. And you can look them up.

01

Banister model (PMC)

CTL is your long-term fitness, ATL your current load, TSB your form today, computed daily from your runs.

After Banister et al., 1975
02

Karvonen / HR reserve

Your heart rate zones from your personal resting and maximum heart rate, not from a one-size-fits-all table.

After Karvonen, 1957
03

Daniels VDOT

You enter your last race time. Runnerd tells you how fast easy, tempo and interval should be for you.

After Jack Daniels, “Daniels’ Running Formula”
04

TRIMP

10 km easy and 6 × 1000 m intervals are not the same. TRIMP makes them comparable: volume and intensity in one number.

Training Impulse, after Banister

FAQ

Good to know.

Three things. First: a real native Mac app, not an iPhone app passed through, serious running analysis on the big screen. Second: no AI, but named models from training science that you can look up. Third: a one-time purchase instead of a subscription, one purchase for both devices.

No. Runnerd records nothing itself. It reads your runs from Apple Health. Recording is handled by your Apple Watch or any app that writes to Apple Health.

Yes, Runnerd reads from Apple Health. If you record runs with another app and they land in Health, Runnerd works. Heart-rate-based analyses need HR data. The Apple Watch delivers it most reliably.

No. Runnerd uses the Banister model for training load, the Karvonen formula for heart rate zones and Daniels VDOT for pace predictions. All algorithms have names and foundations. No machine learning, no black box. The texts from your coach are not AI either. The sentences are written by hand, your numbers decide which one appears. Sometimes one repeats.

A value between 0 and 100 showing how ready you are for load today. It is calculated from four factors: HRV (30%), resting heart rate (20%), sleep (25%) and TSB from the PMC (25%). It gets more precise with more data.

In your iCloud. Runnerd has no server of its own. Your run data comes from Apple Health; syncing between iPhone and Mac runs exclusively through your private iCloud (CloudKit), encrypted via Apple’s infrastructure.

There is no Health app on the Mac, so your runs are not there. The Runnerd iPhone app reads them from Health and syncs them to the Mac via your private iCloud. On the Mac you then get the big screen for analysis.

Runnerd is free and stays free. Pro unlocks the full analysis depth: a one-time €8.99, one purchase for iPhone and Mac. No subscription.

German and English, in the app and on this site. Runnerd is available worldwide on the App Store.

Origin

Why Runnerd exists

I always wanted to look at my running data on the Mac. Not in passing on a phone, but properly and in detail, on a screen big enough to hold several years side by side.

Since nothing like that existed, I first built myself a local HTML/JS application that could read the Apple Health export. It ran in the browser on my own machine and answered exactly one question: how is my form developing over time? Runnerd grew out of that.

If something is missing, or a number doesn’t look right to you, write to me: hello@runnerd.de

Your runs are already in Apple Health.
