The stupid app is a non-starter. I cannot imagine a single bank in the United States that would want to be associated with it.
Aside from the scrutiny banks must be under right now, can you picture a bank telling a customer: "we have an app that helps you save by starting with change and then compounding it daily by using an exponential numeric value"?
The only way out of this mess is with a new pump of bs about some other nonexistent product, person, company, etc.
