Can a Beginner Use This App

Yes. RunDNA is built for every runner, from someone just starting out to competitive athletes, not just advanced or elite runners. 

RunDNA's whole approach is designed around the everyday runner, not just the fastest ones. The coaching model doesn't assume any prior training background; it starts by looking at how you personally move, whatever your experience level, and builds from there. 

There's no such thing as perfect running form. There are only imperfect ways to run, and every runner, beginner or elite, is working with some version of that. A beginner isn't held to a different standard here; the assessment just meets you where you are and points to what would help most. 

You don't need race experience or a training history to benefit from understanding your movement patterns. If anything, catching inefficient patterns early, before they've had years to become habits, can make a bigger difference for newer runners.
