Has anyone used Acorn?

I just opened an acorn account and started with $20. I am wondering if anyone else has used this platform to save and invest. I found this site at the bottom of my PayPal app. I do have a referral that would give you $5 when you invest if your interested. Kind of gun shy due to bitconnect =(
I do want to say no matter where I invest I can always count on my scrapping to make extra money.

Haven't used it but found this comparison with similar apps a useful read https://www.nerdwallet.com/blog/inve...acorns-review/
