Athletes use the CrewNerd application in their boat (rowing shell, kayak, canoe, etc.) to monitor their own performance data and, if they wish, to relay their location and data through the internet to coaches or spectators via the CrewNerd viewer. When tracking is turned on by the athlete, CrewNerd will send updates to the CrewNerd cloud service approximately once per second.
Athletes configure CrewNerd with a boat name, club name, and (optionally) a password. All athletes in a club or team should use an identical club name. A password can be used to make sure that people can't see your data simply by guessing your club name. If you aren't concerned with keeping your data private, you can leave the password field empty. The boat name configured by the athlete can be anything, but should be chosen to be meaningful to coaches and spectators.
The first time you use the CrewNerd viewer, it should take you directly to the configuration window. If you don’t see the configuration screen, or if you wish to make changes later, look for the settings icon ( ) in the upper right corner of the screen. On small screens, you may need to press the button in the upper right to make the navigation bar items visible.
Once you get to the settings screen, you should enter the club name and password given to you by your athlete or coach. If a password is being used, enter that as well.
In addition to the club name and password, there are two checkboxes to determine whether to use a dark or light theme for the viewer page, and whether to show the viewer’s position on the map in addition to the athletes. This will only work if you’re viewing from a smartphone with GPS. You must also give permission to the CrewNerd application to track your position when asked by your web browser.
When your configuration is set correctly, press the “Save changes” button to record your settings and return to the main viewer window. Your settings will be saved and reused the next time you run the viewer (for most browsers).
When your configuration is set, you can start the viewer by pressing “Start viewer” on the upper right side of the viewer window. This tells the viewer to begin checking for updates from the CrewNerd cloud service. The viewer checks for new updates approximately once per second, and continues checking for new data until you press “Stop viewer” or close your browser window.
The viewer starts on the “table” view, which shows data for all boats currently being tracked. Boat names are shown in red if their timer is stopped, and green once their timer is started. The icon next to each boat name can be used to locate the boat on the map view.
The format of this table can be easily customized to suit your screen size and personal preferences. Use the Col and Col buttons on the top navigation bar to add or remove data columns. Use the and buttons to change the size of the text in the table.
After setting the number of columns and the text size to suit your screen size, use the column headings to choose the data you wish to see, and to order the boats in the list. Press the right side of a column heading to show a drop-down list of available data. Tap the desired data type to show it in the column. Tap on the left side of a column heading to sort the boats according to the data in that column. Tap again to reverse the sort order.
Press the “Map” button to see all of the tracked boats on a map. If you don’t see anything on the map, try pressing the “Center map” button to center the map on the boats being tracked and adjust the zoom factor so that they are all visible. The boats will be shown with icons labeled A through Z as indicated on the table view. Your position will also be visible if your device supports it and you elected to show your position in the configuration settings.
Tap on one of the boat icons to see the data for that boat just above the map. You can also zoom and pan manually with the map to adjust it to your liking.
The history view shows summary information for each workout interval completed by the crews that you view. The history view is loaded once when you start the viewer with any intervals completed in the last 24 hours. The history view is not refreshed automatically as new intervals are completed to avoid interrupting you as you look over the data. A message will appear next to the “Rebuild history” button telling you the number of new intervals that have been completed. To add the new intervals to the history page, press “Rebuild history”.
The conditions view shows the current conditions at the location of the boats you’re tracking, including temperature, wind speed and direction, cloud cover, visibility, and humidity. Press the “Refresh” button to get the latest update.
