Workout & Auto Piece Timer settings

Choose the live piece-detection settings before you row. The workout saves the settings used for that session.

Auto Piece Timer

The Auto Piece Timer (APT) identifies continuous work intervals. In Workout Settings, choose the trigger and thresholds for your session.

ControlMeaning
APT TriggerRate uses the stroke-rate threshold; Power uses power; Both requires both; Either accepts either.
Rate / Power ThresholdThe effort required to qualify. Power-based detection depends on the active oar calibration.
Min DistanceFilters very short pieces from the summary.
Auto Piece Time CutoffHow long inactivity may continue before the piece ends. Repeated non-qualifying strokes can also end it.
Piece RoundingChoose distance or time and its rounding increment.

Detection needs confirming strokes. A piece’s final endpoint may move back to its last qualifying portion once rowing falls below the trigger or stops.

Other settings worth checking

Use the ? beside a setting for its explanation. Choose the measurements for your display in Rowing Views → Available Metrics & Curves; the metric catalog explains what each core item measures.

Oar settings and water reference

Side, type and Moment/Bend Factor come from the selected oar. Check the source and any override in Oar Settings. The recording captures the applied scale and saved dimensions.

After saving sensor alignment, you can capture an optional 12-second Squared float and save it to Oar Settings. This records a separate water reference; a measured shaft-axis tip depth is optional and must be entered if known. A float without that measurement does not establish absolute water depth.

Where a manual waterline below pin (cm) is entered, measure vertically from pin to water surface with the boat level; positive means below the pin. Manual entry takes priority until cleared. Check the reference again after rigging or boat loading changes.

Changing settings for future workouts does not alter a session already recording.

Calorie estimates

Open Workout Settings → Calorie estimates. For work-based calories, review Work efficiency and Work represented against the recorded setup. The default 20% efficiency is an assumption, not a measurement of your personal efficiency.

For heart-rate calories, enter Body mass (kg), Resting heart rate, Maximum heart rate and VO₂max (mL/kg/min), and record heart rate during the workout. The app starts with 65 bpm resting and 170 bpm maximum; replace these defaults with your personal values. Missing recorded heart rate, body mass, VO₂max or supported duration leaves this estimate unavailable. The current work and heart-rate estimates are separate Body choices under Advanced.

The metric reference explains these methods and the planned mechanical-energy, HR-profile and combined estimates.

Review or re-run later

After End Row, let the workout finish saving and processing. Home and history show its progress; you can start another row while the earlier workout finishes analysis. Open Cloud Analysis and choose Analyze latest or Choose a workout. Review the recording’s settings and included data before uploading. To automate the upload, enable Upload after each workout; pending uploads retry while the app is open and when you return.

Use Change Settings and Re-run to rerun detection, grouping or processing while raw files remain available. Use a new upload for a different recording. The finished HTML report’s temporary calibration adjustment updates effort-derived values but keeps its generated pieces and groups fixed.
