No, all existing Tip Yourself accounts will be closed and new accounts will be set up with Earnin. Existing Tip Jars and savings challenges will not transfer over.
You'll find some features of the existing Tip Yourself app have not been carried over to Earnin. Some of these will be retired completely and others will be added to Earnin in the next few months.
We'd love to hear from you on how we can make the Tip Yourself experience within Earnin the best it can be! Feel free to reach out to firstname.lastname@example.org with any thoughts and feedback.
