The premise of Digit is that the app has access to your checking account and "learns" your spending habits, before working out how much money it can save for you. Each day, Digit will take an amount from your account and put it in your "Rainy Day" account within the app. You can withdraw this money at any time — but the idea is that you don't.
My relationship with Digit started off great! On the first day it saved $1.14, then $6.50, then $1.05. For two weeks, I enjoyed it a lot — I didn't notice the cash slowly dripping from my account but loved opening the app and seeing I had saved money! Without even trying! But then, things started to go a little haywire. After two weeks of saving, Digit started taking much larger chunks of money from my account: $16 one day, $18 the next. It was too much. The rise in saving didn't actually reflect any influx of cash in my bank account and within a few days, Digit had almost drained my account — I had to press pause. A lot of coworkers mentioned having similar experiences, even after they repeatedly told Digit to save less.
After my next pay day, I un-paused the app and let it do its thing once again — but I've been keeping an eye on it. I love the premise of Digit and it's definitely helped me save money I otherwise would have spent — probably on over-priced work lunches — but it definitely need monitoring.
Did it work? Yes and no. Yes in that I saved money, but no in that I don't trust the app. This would probably work better for someone with more disposable cash than me.
