We are working on the documentation for the application. To get you started a primer of the main screen is below. Tap on any of the graphs to zoom in on the live picture.
The heart rate data read from your heart rate monitor is recorded in a text log file. The file is in the standard “CSV” format and can be imported into spreadsheet like Microsoft Excel or Google Docs. The log files are on your device’s SDCARD, in a directory named “hrmlog” . btScale always writes its log to the file named “hrm.log”.
Every time you select the “Restart Workout” option the “hrm.log” file will be renamed using the current date and time. A new HRM.LOG file will then be created. You can delete any of the logs in this directory at any time they are not in use.
