Stash's app is really designed and easy to use for beginning investors. Stash is similar to Acorns except they guide you in choosing ETFs to purchase. You can invest into ideas like "Colossal China" (Chinese stocks) or "Clean & Green" (Clean energy stocks) so it is similar to Motif in that sense. It is very easy to recreate Stash's recommended investments using something like Robinhood so that is an alternative if you don't want to pay a fee. I'm probably not going to use this long term just because I can use free alternatives but Stash is good if you want something easy to use and don't mind paying a little bit of money for it.
