Depends on where you live. In Canada I use Shakepay

Anyone know of USA options?
I'm in the US
Cake Wallet, but certainly don't use for your main stack. You can offload into gift cards, etc.
Also heard good things about bitrefill...
You could also look into using Bitwage, and split pay between Bitcoin, usdc, etc...
Currently using Bitwage, so can personally testify their service is spectacular.
