Spartn 3.1: Your Personal AI Coach Gets Smarter
We're excited to announce Spartn 3.1, our biggest update yet! This release transforms Spartn into an intelligent fitness companion that learns from your body, adapts to your progress, and coaches you to better results.
🫀 Real-Time Heart Rate Training
Train smarter, not just harder. Spartn now tracks your heart rate in real-time during workouts using your AirPods Pro 3 or Apple Watch.
What's new:
- Live heart rate monitoring - See your current heart rate as you exercise
- Training zone tracking - Know exactly when you're in fat burn, cardio, or peak zones
- Visual zone history - Review how much time you spent in each intensity zone after every workout
- Precision calorie tracking - Get 30-50% more accurate calorie estimates based on your actual exertion
Whether you're trying to maximize fat burn or push your cardio limits, you'll now have real-time data guiding every rep.
🧠 AI Coaching That Actually Understands You
Spartn's new AI coaching system analyzes your workout history, recovery patterns, and performance trends to give you personalized feedback after every session.
Your AI coach now:
- Predicts optimal workout difficulty based on your current recovery state
- Provides post-workout insights and recommendations
- Adjusts future workouts based on your progress
- Tracks your fitness level evolution from beginner to advanced
Think of it as having a personal trainer who's been with you since day one, remembering every workout and recovery pattern.

Recovery is where gains happen. That's why we're making Recovery Score tracking available to all users (previously premium-only).
Your daily Recovery Score now factors in:

- Personalized recovery patterns
Start your day knowing whether to push hard or prioritize recovery.
