The world's first AI coach that talks to you mid-run. Real-time voice coaching through your AirPods, based on your live heart rate. It's like running with a coach who knows your body better than you do — start your free 7-day trial. While other apps just track your run and send you a static training plan, Zetra adapts every cue to what's happening right now. When your heart rate spikes, your coach eases you back. When you're cruising, your coach pushes. When you're fading, your coach protects you. YOUR COACH ADAPTS IN REAL TIME Every cue is personalized to your goal, your fitness level, and the exact moment you're in. No two coaching sessions are the same — because no two runs are the same. • Live voice coaching through AirPods, every step • Real-time heart rate, pace, and effort analysis on Apple Watch • Personalized to 126 different runner profiles — from couch-to-5K to marathon • Form cues mid-run: cadence, breathing, posture, stride • Adapts to weather, recovery, and how your body actually feels today WHO ZETRA IS FOR • New runners who want a coach in their ear, not just a stopwatch • Returning runners rebuilding base fitness without overdoing it • Half marathon and marathon trainees who can't afford a $200/hour coach • Apple Watch + AirPods users who want their gear to actually coach them WHY VOICE COACHING CHANGES EVERYTHING Looking at your watch mid-run breaks your rhythm. A voice in your ear doesn't. When the coach says "ease up — you're in zone 4 on an easy day," you adjust without thinking. That's how real coaches train you. Zetra brings that experience to every run. WHAT YOU GET • Live voice coaching on every run • Personalized training plans for 5K, 10K, half marathon, marathon • Heart rate zone training that actually adapts day-by-day • Detailed post-run analysis — effort, drift, recovery • Apple Watch standalone mode (leave your phone at home) • AirPods integration for crystal-clear coaching outdoors PRICING & FREE TRIAL Start with a 7-day free trial. After that: • $2.49/week • $9.99/month • $59.99/year (best value — under $5/month) Cancel anytime. Subscriptions auto-renew unless turned off in your Apple ID settings. REQUIREMENTS iPhone running iOS 17+ and Apple Watch running watchOS 10+. AirPods or any Bluetooth audio device recommended for the live coaching experience.
