Qoins - get rid of you debt, using spare change (US only)

Just when I was thinking everything was invented, our fellows from over the ocean surprised us once again. Now, how to describe this, if you already read my reviews about Acorns (US) and Moneyboxapp (UK), imagine Qoins as a Moneybox for debts, instead of investments. This a a very good idea, just because many of us will not start to invest until we will pay all our debts. Or will we? So, you have debts, this is your solution, one spare change at the time. I cannot tested yet, as I am in UK at the moment, but I wait impatiently for someone to do this over here too.
