Rocket Money is advertising itself as the consumer-friendly budget tool but if you really wanted to help people, you would have ways that would trigger alerts to make sure the person can afford your service and see if they're being charged twice for your service. Additionally you should be able to provide feedback to the people about areas in their spending that look problematic, like paying twice for any subscription, for instanceRegardless if it was for rocket money or something else. Taking this theme further I'm sure that your product owners and engineers would be able to create many more alerts that would help people with issues related to this and others.
