The metaphor comes with limitations, though. If you get a lot of phone calls, habitually check in on Swarm, or follow more than a couple of teams, the timeline quickly gets cluttered. And for better or worse, very few things fit in the paradigm—there's no searching, no initiating of messages with Pebble.
The interface is just rough. It's cartoonish and slow, with goofy animations I'd rather not watch when I simply want to see my next appointment. (The animations apparently are a hack for dealing with e-paper's slow refresh rate, but that doesn't make it better.) Some screens are too dense with text and information, and others show a huge image where an icon or simple line of text would do. Every app looks different, and if you have more than a few on your watch, it gets really hard to sort through them. The more you try to do on the Time, the harder it gets to use.
The screen isn't touch-enabled, either, which took some getting used to after swiping and tapping around the Apple Watch and the many Android Wear devices. You do everything with four buttons, three on the right and one on the left. It's basically a D-pad: you go up, down, left, and right through the Time's interface. Of course, Pebble's not done, and some of these problems soon will be ironed out. "Soon" is something of a catchphrase for the Pebble Time. Soon you'll be able to buy "Smart Straps" and add new features to your watch. Soon you'll be able to use the Time's built-in microphone—which works pretty well, by the way—to do much more than reply to messages. Soon your watch will control your smart home, connected via Bluetooth to all your light bulbs and smart locks. Pebble has grand ambitions about becoming a playground for developers.
But little of that works right now.
And more likely than not, hardly any of it will work with your iPhone. The Time, or any Pebble really, is dramatically more useful if you have an Android device. On iPhone, it's crippled absolutely everywhere. You can't take action on most notifications. You have much less control over what you see and what you don't. You can't control your phone from your watch, really. Even the connection itself doesn't work as well. Most of this is surely Apple's doing, but it's not likely to get any better—Apple wants to sell Watches, not the Pebbles, and its relationship with Pebble is increasingly fraught as a result.
These limitations are so frustrating because there are good ideas in the Pebble Time. Using time as the interaction metaphor is smart and easily grasped, and there’s something to be said for not trying to be all things to all people. It's not trying to replace your phone, or create new behaviors or features—it just wants to give you a clear picture of what's happening in your life, right now. That's seriously compelling; maybe a smartwatch doesn't need to search Google or Shazam a song or check me into my hotel; maybe it just needs to be able to tell me what to do about the fact that it's 3:05 PM right now.
