Indoor cycling & ERG workouts

Free

WattLog.pro turns your iPhone into the ultimate indoor cycling companion. Connect your smart trainer (Wahoo KICKR and other FTMS devices) and heart rate monitor via Bluetooth Low Energy to start training with real-time data, structured workouts, and intelligent analytics. REAL-TIME DASHBOARD Monitor everything in one fully configurable view. Track power, cadence, heart rate, Normalized Power (NP), TSS, Efficiency Factor (EF), and rolling averages exactly how you want them. SMART TRAINER CONTROL Take full control of your indoor ride: • Ride in ERG mode for precise power targets. • Set resistance manually. • Simulate any GPX/TCX route with accurate, physics-based grade simulation. STRUCTURED WORKOUTS Build custom intervals or choose from our curated plan library featuring 8 programs for all levels (beginner to advanced). Countdown overlays and sound cues ensure you stay right on target. PRO TRAINING ANALYTICS Take the guesswork out of your fitness: • Track your form with a Performance Management Chart (CTL/ATL/TSB). • Detect aerobic decoupling. • Monitor your efforts across 7 Coggan power zones. • Get daily HRV readiness scores (1–100) to optimize your recovery. PERSONAL RECORDS & SEGMENTS Push your limits. WattLog.pro features automatic PR detection for 1, 5, 10, 20, and 60-minute max power efforts, plus support for custom segments. SESSION COMPARISON Analyze your progress over time by overlaying any two sessions on a shared time axis. See exactly where you’ve improved. Note: WattLog.pro requires a Bluetooth-enabled smart trainer or power meter and a heart rate monitor for full functionality.
