I currently use Qapital and Acorns and there round-up and weekly deposits to save money. Also I purposely do not spend my coins. I will break a dollar on purpose just to get the change. We put the change into a jar and deposit it into our bank every year near Christmas. Also, I consider this saving, of some sort. We run all of our daily living expenses through our credit cards that earn miles. We pay for everything via our credit card and whatever we spend during the day we pay off that night. That way we earn the miles. Also if you have a balance and run your money through your card and it is equal or greater than the balance we never pay interest even on a balance because we are technically paying off the existing debt every month.
