Yes. It's basically an MVNO that resells on Sprint, TMO, and US Cellular, while trying hard to keep calls and data going over WiFi. As a consequence of that, it only works on newer phones that can do fast handoff between WiFi and cell. I use it. It works pretty well. My wife is still on Cricket and she got better coverage in the mountains of Colorado this summer, but I've been happy everywhere else. The pricing is very as-you-use it, which works well for some people and not as well for others (it's great for people who use very little data but want flexibility; the international data roaming is amazing; it's more expensive than other plans for multiple-GB/month users). I put together a spreadsheet (copyable, google sheets) for comparing price vs GB/data used when I was trying to figure which carrier to use.

(Updated: I just updated the pricing, since it was getting a little stale.) (Ob disclaimer: I'm part time at Google, but have no beans in the cellular stuff.)
