User engagement and retention platform for blockchain applications. SimpleID is the platform for increasing user engagement and retention in blockchain applications. For the first time ever in Web 3.0, we enable an ongoing relationship with your users even after they've left your application, thus solving the DAU and MAU problem plaguing the industry. Through a custom mapping system, we offer developers and founders the ability to send in-app and out-of-app notifications to their users. But more importantly, we provide blockchain-specific analytics filtered against your application to help you segment groups of users that you may need to re-engage.
