Hi Product Hunt! I'm the maker of Stride Pro.
What inspired you to build this?
As a marathoner and trail runner, I rely heavily on my Apple Watch for high-mileage training. I wanted a tool that functioned like a true AI coach—one that understands serious training metrics but operates entirely within the native Apple ecosystem, allowing me to leave my phone behind when heading into the mountains or onto the track.
What problem were you trying to solve?
Most running plans are static, and manually transferring complex interval sessions to a watch is tedious. I needed a way to deeply analyze HealthKit data and morning HRV to dynamically adjust daily workouts. The core problem I solved was writing these tailored, auto-generated sessions losslessly and instantly to the native Apple Watch workout app, removing all friction before a run.
How did your approach or process evolve while working on this launch?
Initially, I focused purely on data visualization. However, while writing the Swift code and working deeply with HealthKit APIs, I realized the real value lay in actionability. The development process shifted from simply reading historical data to actively generating and pushing structured marathon PB plans directly to the wrist. It evolved into a seamless bridge between complex training logic and the native watch experience.
The HRV-based daily adjustments actually felt dialed in for once, not just generic plans with a fancy skin. Writing workouts straight to the native Apple Watch app is a really nice touch.
Native watch face complications would be huge for quick glances mid-run. The app sounds like it handles the heavy lifting during workouts, but having a complication that shows today's planned workout type or current readiness score right on the face would save me from opening the app every morning. Maybe even a small ring showing how the workout intensity maps to my weekly load.
