## What is Arc?

Arc is your self-coached endurance training partner. Answer a few quick questions and Arc builds a personalized plan — then adapts it every week to how your body is actually recovering. No coaching degree required.

Whether you're training for your first race or just want to get fitter and build a consistent habit, Arc meets you where you are and explains every step in plain English.

BUILT AROUND YOU
• Tell Arc your goal and schedule, and it generates a structured, periodized plan that ramps up sensibly and eases off before race day.
• No race? Choose "Get fitter" for a rolling plan that steadily builds your fitness with recovery built in.
• Beginner-friendly throughout: tap any training term to learn what it means, with gentle defaults so you never feel overwhelmed.

READINESS FROM APPLE HEALTH
• Arc reads recovery signals like resting heart rate, heart rate variability (HRV), and sleep to estimate how ready you are to train hard today.
• A simple 0–100 score with a plain-English call: push, hold steady, or take it easier.
• Add a quick daily check-in to sharpen the picture on days with little data.

ADAPTS AS YOU GO
• Each week Arc reviews your training and recovery and suggests adjustments — easier, harder, or unchanged. Nothing changes until you approve it.
• Life happens. Arc keeps your plan realistic instead of guilt-tripping you.

TRAIN ACROSS YOUR DISCIPLINES
• Running, cycling, swimming, and strength — with key sessions focused on your goal.
• Clear daily workouts broken into easy-to-follow segments with intensity targets.

WORKS WHERE YOU DO
• Apple Watch app and complications to see today's session and readiness at a glance.
• Home and Lock Screen widgets.
• Export your plan to Apple Calendar.
• Import completed activities so your plan reflects what you actually did.

MAKE IT YOURS
• Choose an accent theme and light or dark appearance.
• Metric or imperial units.

PRIVACY FIRST
• Arc reads recovery and workout data from Apple Health to personalize your plan. It never writes to Health, and your data stays on your device and in your private iCloud.

ARC PRO
• Health-driven readiness, automatic weekly adaptation, and morning check-in reminders are part of Arc Pro.
• Subscriptions are billed through your Apple Account and can be managed or canceled anytime in Settings.

Start where you are. Arc handles the rest.

## Version history (last 2 releases)

### 1.2 — 2026-07-30

Arc 1.2 — train smarter, everywhere.

This update brings your plan to your Lock Screen, your voice, and your language—plus a smarter coach and gentler comebacks from setbacks.

Live Activity & Dynamic Island
Today's session lives on your Lock Screen and in the Dynamic Island, with your readiness at a glance—and it updates the moment you mark it done.

Ask Siri, Spotlight & Shortcuts
"What's my readiness?" or "Log my workout"—Arc now answers and acts from Siri, Spotlight, and the Shortcuts app, without opening the app.

Control Center controls
Add a readiness tile or a one-tap "Log workout" button to Control Center, the Lock Screen, or the Action button.

Now in Spanish
Arc is fully localized in Spanish—app, widgets, watch, and Siri.

Workout-day reminders
Get a morning heads-up on days you have a session planned.

A coach that explains your plan (Arc Pro)
The on-device AI coach now understands your plan's structure, so it can tell you why it's built the way it is—and start each week with a short, encouraging recap.

Weather-aware pace guidance (Arc Pro)
On hot or cold days, Arc suggests how to adjust today's effort so you train smart in tough conditions.

Injury & illness recovery (Arc Pro)
Hurt or sick? Log a setback and Arc rests the coming days, then eases you back with a gradual ramp. Days off count as rest, not missed—and your race date never moves.

Thanks for training with Arc. Questions or ideas? We'd love to hear from you.
