I'm new to Rover. Is it possible to practice before a get a client using the Rover Card on my smartphone? Is it possible to get some practice experience with it before I need to do it for real with a client?

Just wondering if it's possible to practice using the rover cards on the smartphone prior to doing so with a paying client? I am new and just want to make sure I understand how to do it all on the smartphone prior to a paid job. Thanks.
