Record GPX tracks using Apple Watch with GPS, iPhone or iPad with GPS. The app uses Kalman filtering on the GPS and Altimeter data to improve accuracy.
WeatherKit is used to store wind conditions at point of recording. Weather View and Widget.
Features export to Strava or multiple other exports.
MapKit is used to acquire GPS location data.
On Apple Watch, HealthKit is used to acquire heart rate data and to export it into the Health app together with the workout activity.
RECORDING FEATURES
-Creates one GPX track with Kalman filtering for latitude / longitude coordinates and elevation.
-Stores wind conditions into the GPX file at time of recording.
-Stores water temperature into the GPX file if available on Apple Watch.
-Works on iOS, iPadOS and watchOS.
-GPX tracks can be pushed from the Apple Watch, imported using the built-in File Importer, or opened from Files App, Email, iMessage.
-Export to Strava or using standard File Exporter
-Recording of accelerometer and gyroscope data
-2Hz sampling with interpolation and accelerometer guessing.
-Acceleration longitude / latitude, user direction and rotation rate.
ANALYSIS FEATURES
-Calculates polar plot
-Calculates VMG (Velocity Made Good) on iOS and iPadOS
-Calculates / finds maximum speeds segments over 2s, 10m, 100m, 1000m and 1852m.
-1, 5 or 25 non-overlapping speed segments
-Toggle data graph between speed, altitude, course, heart rate (if available), horizontal accuracy and cumulated upwind distance
-Allows to select a segment with marker to calculate distance, time and average speed
-Direct select of speed segments in sortable table
-Finding tacks, jibes and crashes with direct select in sortable table
-Allows to crop samples, decimate by 5, detect and cure glitches
-Supports importing multiple tracks (iOS and iPadOS only) with overlay in the chart metric
-Import filter for GPX files with sortable table
-Weather for local and favorite location
-Weather widget to not miss the upcoming wind conditions. Widget is interactive with toggle either showing local or favorite location.
WATCHOS EXTRA FEATURES
-The heart rate on watchOS uses linear interpolation between heart rate updates so that each GPS sample point will have a valid value in the GPX log.
-The workout will also appear in the iOS Fitness app together with the track log (HealthKit).
-The total distance is shown as a widget or current local wind speed is shown
