can APP save data to file?

Create a log file and use System.println() or similar to write to the file. You must create the file manually. In the /GARMIN/APPS/LOGS dir create file [appfilename].txt

Is it possible to write data to the .fit file, too?

same quesiton as me.

Writing extra data to the .fit isn't possible today, but has been discussed many times, so probably in a future SDK/FW.

Save and retrieve the data using setProperty( "key", data ) & getProperty( "key" );
