A friend of mine told me about Digit and how it analyzes your bank account activity then makes small withdrawals and deposits them in your Digit account. You can change how aggressive you'd like to save and even save a set amount. So far, I've saved $245.20 without even feeling the pinch. And transferring your savings from Digit back into your checking account is as easy as a text message.
Another easy way to save is with Acorns investing app. This program rounds up your change from your checking account transactions and invests it. I've saved about $90 but with investments and found money, my account is at $105.98.
