Hi everyone,
I’m excited to share a project I’ve been working on: Intelligent Coaching Utility ICU Coach, a mobile companion app designed specifically to extend the power of Intervals.icu with advanced AI-driven insights and automated coaching.
A bit about me
I’m a solo developer and a triathlete. Like many of you, I spend a lot of time analyzing my data here on Intervals.icu. I built ICU Coach out of my own needs as a triathlete—trying to balance Swim, Bike, and Run while making sure I’m recovering properly and hitting the right intensity at the right time.
ICU Coach isn’t just a generic fitness app. It understands the nuances of multi-sport training. Whether you are focused on a single discipline or balancing all three, the app uses your Intervals.icu data to provide a “Single Source of Truth” for your training.
Key Features
AI Coach: Generates personalized daily workouts based on your current fitness, fatigue (CTL/ATL/TSB), and specific training goals. It adapts in real-time to how you are actually recovering.
Recovery Pro: A multi-system recovery engine that tracks Metabolic, Neuromuscular, and Hormonal systems. It uses a “Percentile Gate” (HRV/RHR) to prevent overtraining and tell you exactly when you’re ready for that next interval session.
Race Predictor: Accurate performance forecasting for your target races using your power/pace data and training history.
AI Performance Labs: Deep-dive analysis into your Sleep quality, HRV trends, and Weekly training efficiency.
Chef AI: Personalized nutrition plans matched to your daily training load and dietary preferences.
The “One-Click” Sync
One of the most important features I focused on is the seamless integration. With the built-in Workout Builder or AI Coach, you can create a structured workout and, with a single click, upload it directly to your Intervals.icu calendar. From there, it automatically syncs to your watch and platforms like Zwift, so you can just hit ‘Start’ and go.
For Coaches
If you’re a coach, I’ve built a dedicated Coach Mode. You can manage your entire athlete roster, monitor their recovery status in real-time, and generate AI-powered reports for your athletes directly through the app.
Check it out
The app is available in 5 languages (EN, TR, DE, FR, ES) and supports both BYOK (Bring Your Own Key) for Gemini/OpenAI and a Cloud AI option for a zero-setup experience.
- iOS: ICU Coach App - App Store
- Android: Soon

I’d love to hear your feedback and suggestions. As a fellow Intervals.icu user, I’m committed to making this the best possible companion for this amazing platform.
Happy training!
