For my son's baseball team, I have been the primary storekeeper, using iScore on my Android tablet. This season, I have missed some games, so another parent put iScore on his iPad and kept score. Is there a way for us to combine our stats? Can he export his stats to my iScore account?

Yes!
You will use what iscore calls "data sharing" ( option >data share > get from web>

You can transfer in games you missed (and they can transfer games they missed if you want)

You both need to update the iscore servers with your data (option > export)
(You then need to share device ID and passwords, you can set a temporary password from your device in options> admin, or go on line to admin web site and set a sharing password, )

This part of on line training explains,

Awesome! Thank you. I'll give it a try.
