iMPlayer is simply an application—it’s not the actual service. It functions as a platform that enables the Drivemob service to run. Think of iMPlayer as the tool, while Drivemob is the engine behind it. Drivemob is the subscription-based service that powers the content, and it costs $36 per month. Without an active Drivemob subscription, iMPlayer won’t work, because it’s just the interface that connects to the service—it doesn’t provide any content on its own.
