What's in the app

Every web calculator ships native. Pace, race predictor, training zones, intervals, nutrition, heart-rate zones, treadmill conversion, age grading, Boston qualifying, plus course-specific marathon pacing for the world majors. Open, plug in your numbers, plan your week.

Race-day share cards

Generate a Story-format card (1080×1920) from any calculator. Three layouts: Broadside (single hero numeral), Terminal (data-rich line items), Minimal (split ink/paper, big numeral). Post to Instagram, send to your group chat — the math is on the card.

What's not in the app

Accounts. Ads. Analytics. Tracking. Cloud sync (yet). The app is local-first by design — your inputs live on your device, share cards include only what you put on them.

How we make money

Optional in-app tips through Buy Me a Bagel. That's the entire revenue model.
