Utilize ‘Pre-registration’ as a marketing strategy before the official launch of an app. Pre-registrations allow users to learn about the app beforehand and easily access it upon release through notifications and automatic installation.

To make the most of pre-registrations, promote them across various marketing channels and consider offering exclusive rewards. This strategy can significantly boost app awareness and anticipation.

Being featured in ONE store's ‘Pre-registration PLUS’ can further enhance your visibility to a broader audience and provide additional rewards, potentially maximizing early performance.
