Yes, it is possible, you just need to (after you have finished your activity) sync the speed cell with the app from the sport you just practiced,
if you go out and play a tennis match with your speed cell, you will need to sync and upload your data with the tennis app,
if you run a race with the speed cell on, you would want to sync your data with the running app.
Data gets interpreted when you upload it to a sport specific app like tennis, basketball, football, etc...
hope this helps

Hey Guys,
@RadW, I just want to clarify - once you sync your workout with one sport app, (ie: the Running app) you will not be able to sync that same data again to another app.
Also, within each app there is the option to save the SPEED_CELL data as another sport. So as an example, you can save SPEED_CELL data as a Tennis workout from within the Running app. This option comes up after the edit data window. Just pick the sport from the drop-down as seen here:
Hope this info helps!
cheers,
