Why Runsy
Not another static plan generator
Most running apps hand you a PDF-with-buttons and call it coaching. Runsy behaves like a coach: it watches what you actually do, and responds.
It notices
Every synced run updates your measured fitness — weekly volume, easy pace, training load. Your plan is grounded in your numbers, not a template.
It reacts
Skip a day, mention a sore knee in chat, or crush a workout — your coming week is rebalanced, and your coach tells you why.
It protects you
Progression stays inside safe bounds: roughly 10% volume growth per week, never two hard days back to back. Ambition without the injury cycle.
How it works
Coaching, not templates
01
Tell Runsy your goal
Your first 5K, a marathon PR, or just running consistently. Two minutes of questions — no fitness test, no jargon.
02
Get a plan that starts where you are
Brand new? Runsy starts you safely from zero with walk-run workouts. Already running? It reads your Apple Health history — pace, distance, heart rate — to set a starting point that's yours.
03
Watch it adapt, week after week
Miss a run, say something aches, crush a workout — your plan rebuilds around what actually happened, and your coach tells you why.
The Runsy difference
Life happens. Your plan keeps up.
Static plans die the first week something goes sideways. Runsy expects it — your plan revises every week, and rebuilds the moment you miss a run or say something aches.
- Miss a day — the week rebalancesYour harder session moves, an easier day slots in, and the progress you earned stays put. No restart, no catch-up cramming.
- Feel beat up — volume eases firstMention soreness and Runsy backs off before a small ache becomes an injury. Progression is capped at safe weekly growth.
- Get faster — paces update themselvesEvery synced run refines your paces. The plan you see tomorrow already knows the run you did today.
Coach chat
Ask anything. It remembers everything.
Pacing, soreness, race strategy, or the questions you'd be embarrassed to ask a human — your coach answers from your full training history, and turns the conversation into plan changes.
Grounded in you
Built on your numbers, not a template
Runsy continuously measures your real volume, paces, and training-load ratio — the same acute-to-chronic signal used in sports science — and keeps progression inside safe bounds: roughly 10% a week, never two hard days back to back.

FAQ
Fair questions
How is Runsy different from Strava or Nike Run Club?
Those apps are great at recording runs. Runsy plans them. It builds a forward-looking training plan from your history, adapts it week by week, and gives you a coach you can actually talk to about pacing, soreness, and race strategy.
Do I need a training history to start?
No. If you have runs in Apple Health, Runsy uses them to set your starting point. If you're brand new, it starts you safely from zero with walk-run workouts.
I run with a Garmin, COROS, or Strava — will my runs count?
Yes — as long as they reach Apple Health. Turn on Apple Health sync in your device's companion app (Garmin Connect, COROS, or Strava) and every run flows into Runsy automatically.
Does it work with Apple Watch?
Yes. Runsy is built for iPhone and syncs through Apple Health, so runs recorded on your Apple Watch — or any app that writes to Apple Health — feed straight into your plan and coaching.
How much does Runsy Pro cost?
US$12.99 per month, shown in your local currency at App Store checkout. New subscribers get the first 7 days free with full access — cancel during the trial and you pay nothing.
How does the free trial work?
New subscribers get full access to everything for 7 days, free. After the trial, Runsy Pro continues at $12.99/month, auto-renewing. Cancel anytime in your App Store settings and you won't be charged.
What happens to my health data?
Your training data is used only to coach you — never for advertising, and never sold. You review exactly what's shared, and with whom, before anything is sent. Full details are in our Privacy Policy.
