Is there a similar to Acorns for bitcoin/crypto?

Basically I’m wondering if there’s an app that can round up any purchase I make to the nearest dollar (or some amount I’d set) and automatically invests that amount into bitcoin.

I’m aware I could set up a weekly or monthly amount to auto withdraw to invest but I kinda like the rounding up concept more. Any ideas? submitted by /u/Scientificupdates
