Calls.app vs Google Voice

Google Voice is a solid product - if you live in the United States, have a US number to verify with, and want a whole second phone line. If you just want to call abroad, it is a lot of hoops.

The big difference: who can actually use it

Google Voice signup requires a US Google account and an existing US phone number for verification. If you are outside the US, or you do not want to link your number, that is a dead end. Calls.app asks for an email and a password - that is it. Sign up from anywhere, call anywhere.

When Google Voice is the better pick

Fair is fair: if you are in the US and want a free second number for texting and domestic calls, Google Voice is hard to beat. If your goal is cheap, no-friction calls to real phones around the world, that is the job Calls.app was built for.
