I want to use my device for something else but I don't want to lose the data I've already scored. Can I exit the scoring app and come back to it?
This is not problem, simply come out of the app and use the device for another purpose, then open up the app and navigate to the 'Matches' section and under the 'Active Matches' section you will find your in progress match. You can also do this to navigate to other parts of the CricHQ app whilst scoring.
