Both options are available. You can buy Smart Runner once with the lifetime purchase and keep it forever, or pay yearly with the annual plan. The lifetime option is built so you can stop paying without losing the app or your training history. No features rotate behind a paywall and every update is included with both plans.

No account, no login, no internet required. Smart Runner works entirely on your device. Your training data is stored locally using Apple's SwiftData framework and never transmitted anywhere.

Smart Runner uses the VDOT model developed by exercise physiologist Jack Daniels. You enter a recent race result (any distance, 5K through marathon) and the app calculates your VDOT score, then derives scientifically valid training pace zones for every workout type.

These are physiological metrics that measure your fitness (CTL), fatigue (ATL), and form (TSB, or Training Stress Balance). You do not need to understand the math. The app shows you a simple form indicator and adjusts your plan accordingly. The science runs in the background.

Yes. The companion Watch app shows live pace, heart rate, distance, and HR zone during your run. You can start and stop workouts from your wrist, and data syncs back to your iPhone automatically when the workout ends.

Yes. On first launch, Smart Runner reads your recent workout history from Apple Health and uses it to seed your training load and fitness baseline.

You get 14 days of full access on first install. During the trial you can build your plan, run with the Apple Watch app, and see every analytic. When the trial ends, choose the lifetime purchase or the annual plan to keep going. Your training history stays on your device either way.

Go to Settings and use the VDOT Override to manually adjust your fitness score up or down. The plan recalculates immediately. If something else looks off, email support with details.

Smart Runner is optimized for marathon and half-marathon training, and supports 5K and 10K targets as well. It generates appropriate volume and intensity for any race distance.

Open Smart Runner, go to Settings, and tap "Restore Purchase." Your App Store purchase is tied to your Apple ID, not to the app install. If the problem persists, email support with your Apple ID receipt.
