<prompt> Human: I am the worst at saving money but I am good at spending it, I saw the Acorns app today and while it will not make me a better saver no behavioral change it will start me actually savinginvesting money without noticing it. I am struggling to find any decent reviews of the app, so I was wondering if any of you have used it and what your thoughts were?I have a .edu email as I am in community college as a mature student so I will not see any of the fees for a while.Assistant: Never heard or someone getting rich off pennies. If you want to invest, you should be intentional with itHuman: Im not trying to get rich, just trying to make saving easy and maybe just create a rainy day fund. I easily could put 5 into the Acorns account per day through rounding up my purchases.Assistant: I easily could put 5 into the Acorns account per day through rounding up my purchases.Why not just take 5 and save it in a savings account at your bank?Human: The savings account at my bank only allows 10 minimum deposit and has a return of 0.25. I think I would get a better ROI if it was invested, I am aware it could be worse or even negative though.  <response>: Its of course up to you, but I think you are overestimating how much money will be saved by Acorns. Assuming an equal distribution of prices between 1 cent and 99 cents, youd have to make 10 purchases a day, every day, to save 5day through acorns without adding other contributions. If you are really making 10 purchases a day, there are probably other spending habits you should improve on before Acorns. Small individual purchases as such are generally bad for your wallet and should be avoided when possible.
