Set up. Row. Review.

Turn on the sensors and open Connect Oar. Choose a saved name, then tap Connect. Use Scan oar label if the oar has a QR label; check that its saved setup matches the physical oar and sensor positions.

For a new oar, choose Set up a new oar, connect its two sensors, enter the name, side and type, then tap Save and connect. Enable Connect automatically next time for the selected name if you want it remembered for the next app launch. Confirm that the expected sensors are connected before starting.

Manage Oars includes saved oars, named pairs and separate managed copies. Choosing a record to inspect does not change which oar is connected for rowing. Check whether you are editing the saved oar or an independent managed copy.

Open Oar Settings → Align Sensors. Record Bias, Feather and square, Feathered level sweep and Square level sweep, then calculate and save the alignment. Repeat after moving, rotating or replacing a sensor.

After the alignment is saved, the optional Squared float captures a water reference. Square the blade, float it on the water with the boat level, hold steady for 12 seconds and tap Save to Oar Settings after an accepted capture. This reference does not change the alignment or bias.

Check the active Moment/Bend Factor (MBF, N·m/°). Use a measured stiffness calibration, a suitable existing Cperm with the current dimensions, or an explicitly chosen manual MBF estimate. Bend shape and timing come from the aligned sensors; calibrated moment, work and power need the correct scale.

Saving a new measured stiffness calibration selects its Cperm and clears manual MBF and manual Cperm overrides. Enter the oar dimensions and sensor positions even when using a manual factor; the recording retains them for analysis.

Secure the iPhone to the boat so it moves with the hull. Keep it fixed throughout the session. Allow Bluetooth, motion and location access when requested; phone motion and GPS provide the boat-motion and speed inputs.

Review Workout Settings and the Auto Piece Timer. In Rowing Views, choose the views you want to use, then tap Start Rowing on Home. Record through the work and recovery intervals. Tap End Row when the whole workout is finished.

The app saves the recording and finishes its analysis. Home and workout history show the progress; history may display Finishing analysis — you can start another row while the workout is being prepared. Wait for it to finish before opening that workout’s complete results. Return to the app if processing or a pending upload needs to resume.

In Rowing Views → Available Metrics & Curves, Core choices start selected. Add your selected numbers and curves to a view under Create & Edit Views, then activate it in Active Rowing Views. A missing input leaves the dependent measurement unavailable.

1. Open Home → Cloud Analysis and sign in.
2. Choose Analyze latest for the most recent workout, or Choose a workout to select another recording.
3. Review its recorded oar setup, analysis inputs and included data. Use Upload Saved Results for supported saved results, or Upload and Run Analysis for raw-data analysis. If that recording already has a server job, the new-upload action can read Upload Raw Data Again as New Analysis.
4. Open the completed report, download it, or use Change Settings and Re-run when the original server files remain available.

For automatic upload, enable Upload after each workout. Upload waits for the workout to finish saving and processing. Pending uploads retry while the app is open and when you return. Review the upload status before assuming the report is ready.

After upload, the recording uses the shared Cloud Analysis and report workflow.

Open the saved workout in history to browse stroke metrics, pieces and groups, and use the available CSV exports. Pieces are continuous work intervals; groups collect similar strokes from across the workout.

Recorded curve views let you browse individual strokes and compare selections. Time views include a quarter-cycle before and after the selected cycle when neighboring data exist. Vertical ranges stay consistent while browsing, and supported curves can show a variability band when enough strokes contribute.

The cloud report adds the session overview, map, animation and report-view presets. Live values can change after a stroke finishes or the workout is processed with its complete recording.

The workout saves the available oar motion, phone motion, GPS and heart-rate data, together with the oar dimensions, sensor positions, alignment, stiffness calibration and applied factor. Enter the dimensions even when using a manual factor.

Cloud Analysis shows this snapshot under Recorded oar settings. Changing the active oar later leaves an earlier workout’s setup intact. Reprocessing older workouts requires their original recordings; a saved summary cannot supply missing sensor data.
