On iOS you can connect and even install apps: Samsung's iOS app is not good, but it's more versatile than a basic Android Wear conduit. I like that the S Health encourages activity streaks - walk for a while, and it shows me how long I've been walking for - and sometimes it borders on fitness coaching. It even recommends stretching exercises when I stand again. Samsung's S Health fitness features are surprisingly good: S Health is the required baked-in way to track fitness on the Gear S, but it does heart rate and automatic activity tracking, can log water and coffee intake, and reminds me when I've stayed still too long. But to use this as an LTE phone, you'll need to pay a monthly fee to add it to your phone plan. Add Bluetooth headphones, and discreet calls can be taken. With AT&T, for instance, the watch can share a number with your Android/Samsung phone. And it's probably the best phone-on-wrist watch that exists. If you want a phone on your wrist, here it is.

It's a full stand-alone phone with LTE: If you buy the LTE model, it can take calls and even connect apps on the go (via AT&T or T-Mobile in the US). But damn, if you like large watches, this is an eye-catching look. But at least it feels really well built and looks high-end. But that design isn't for a lot of people, and loses universal appeal as a result. The big (and I mean big) design feels like a massive sports watch on my thick, hairy wrist. The design: The Gear S3 comes in two designs, both far more "regular watch" than the futuristic but excellent-looking Gear S2. Spotify works for stand-alone streaming, but it'll chew up battery. Last year's S2 was innovative, but it needed polishing. And yet, it fails to take enough leaps forward in its software. In terms of hardware, it's a better watch than last year's bold, clever Gear S2. And few of those apps actually use the Gear S3's standalone LTE. But unlike the latest Apple Watch and Android's upcoming 2.0 software update, Samsung's Tizen-based Gear S3 doesn't do enough to improve the experience or support more apps. The Gear S3 is an insanely feature-rich smartwatch with a big, bold design.

Use-anywhere wrist payments that are even more versatile than Apple Pay? Yes. Stand-alone cellular LTE connection without a phone? Check. If you're looking to see where watches will go next, Samsung's exploring the ideas now. The problem is that the Gear S3 still feels like an experiment, when, in its second iteration (the S2 was the first major redesign), it should really start feeling like a more mature, polished product.
