OneMedical bills your insurance, so you're responsible for buying insurance plus all copays and deductibles. It looks like Galileo offers many services with no insurance required: https://galileo.helpscoutdocs.com/article/55-i-dont-have-ins...

Q: I don't have insurance, can I still use Galileo? A: Yes! Your monthly or yearly membership fee will cover all the care you receive within the Galileo app.

idk about the new thing but OneMedical’s per-visit costs were quite high.
