What's New in 2.5 - Programmed HR workouts: run structured heart-rate sessions like the Norwegian 4×4, or build your own with the new program editor - Smarter HR zone control: faster response when your heart rate drifts, quicker zone changes, and steadier resistance while cruising - New Response setting (Sloth / Standard / Hurry) — adjustable mid-ride — to pick how assertively power follows your heart rate - Configurable power range for HR workouts keeps automatic control within sustainable bounds - Skip steps mid-program, and customize HR zones and max heart rate

- Workouts now correctly appear as Indoor Cycling in Apple Health and Virtual Ride in Strava - Simplified HR zone workout status labels for clarity

- Your Max HR and target zone settings now persist between sessions - Customize HR zone boundaries in Settings to match your training plan - Slider control for Max HR selection — faster and more precise - Confirmation dialog when stopping a workout to prevent accidental taps

Major Feature: PID-Based HR Zone Control The HR Zone workout mode has been completely redesigned with a PID (Proportional-Integral-Derivative) controller replacing the previous step-based algorithm. This provides smoother, more responsive power adjustments to maintain your heart rate within the target zone. How it works: - Feed-Forward (FF): Estimates initial power based on your FTP and target HR zone - Proportional (P): Responds to the current HR error (distance from zone midpoint) - Integral (I): Corrects for sustained offsets over time, ensuring you reach and stay in zone - Derivative (D): Dampens oscillations by responding to HR rate of change The algorithm uses exponentially-weighted moving average (EWMA) filtering on heart rate to reduce noise while maintaining responsiveness. HR Zone Workout UI Improvements - Real-time Power & HR Chart: Live visualization showing power (orange) and heart rate (red) over time, with colored zone bands that update as you change target zones - Zone Transition Tracking: Automatically tracks when you change zones (e.g., "Z3 (5m) → Z5 (2:30) → Z2 (1m)") and includes this in TCX exports and Strava uploads - Algorithm Status Display: Shows real-time PID breakdown: 135 + 99 (+58, +40, +0) = 204 showing Feed-Forward + PID correction (P, I, D terms) = Target Power - HR Trend Indicator: Visual pill showing Rising/Rising Slow/Stable/Falling Slow/Falling with color coding - Compact Single-Screen Layout: All information visible without scrolling - zone picker, chart, HR display, algorithm status, and metrics Export Chart Enhancements - Zone transition visualization in exported charts (colored bands showing which HR zone was targeted during each period) - Cleaner power visualization for HR zone workouts (line only, no area fill to avoid competing with zone bands) Refreshed UI Updated HR Zone workout screens with a cleaner, more compact design matching the app's landing page style, including a real-time Power & HR chart with zone visualization
