Frequently asked questions
Is Stride free to use?
Yes. The Standard 8-Week Comeback program and the full run/walk interval trainer are free. Stride Pro ($4.99/month or $39.99/year) unlocks the AI-personalized training plan and weekly AI coaching.
What does the weekly AI coach actually do?
It reviews your knee journal entries against your recent training load and tells you whether to progress, repeat, or pull back before your next week — a second opinion grounded in your own data, not guesswork.
Is my knee health data private?
Stride is local-first — your journal entries, workouts, and program data live in SQLite on your device. The only thing that ever leaves your phone is the weekly AI analysis request, which goes through Stride's backend, never directly to a third party.
How much does Stride Pro cost?
$4.99/month or $39.99/year, billed through the App Store. You can cancel anytime in your iOS subscription settings — no separate account or web login required.
