Most running apps just beep at you. Run. Walk. Repeat. They don't care if you're struggling or pushing toward injury. Stride AI watches your heart rate, pace, and cadence in real time. It catches fatigue before you crash, adjusts your workout to how you're doing, and coaches you based on what your body's telling it. Works with Apple Watch, Garmin, Fitbit, Samsung Galaxy Watch. First 5K or chasing a PR? Train with a coach that adapts to you.
