Pros -4 day battery, even under heavy use
-AWESOME design, much better than plasticky Pebble
-Super simple, intuitive UI
-Comes with two straps, metal and leather
Cons -App store is SLOW on my iPhone 4s
-Lots of worthless/repetitive apps in store
-Background fast app switching in iOS severely limits usability (but I'll share a fix for that below)
-Some missing features
Summary This is my first smart watch or wearable tech in general and I have to start a word of warning: YES, these devices are generally a waste of money. The only reason you should get one is if you think it's a cool idea and you have an extra $250. The single useful feature is the ability to secretly read your incoming texts/notifications while at work, in class, on a date, or in a situation where pulling out your phone is RUDE or frowned upon by that professor-who-already-doesn't-like-you. At all other points you'll probably just end up pulling out your phone anyway to reply.
Now, to the less useful stuff. This watch is truly good looking, as in, goes well with a tux at the opera or at a cocktail party. At least as long as you remember to switch from Hobbit Time watch face to something a little more classy, which, btw is super simple: just press the up or down buttons to change watch faces. To make the look a little more flexible you are provided with two bands, stainless steel and leather. I prefer leather most of the time since that goes better with my ancient blue jeans and my favorite stained t-shirt.
Apps on the Pebble are a bit hit and miss. I've downloaded about 20, but only 5 have earned one of the 8 seats in my Pebble. These are the ones I'm currently using:
-Smartwatch+, requires companion app but give me fast access to 3 day forecast, upcoming calendar events, current GPS location/elevation, and a handy FindMyiPhone button that makes your phone beep as long as the watch is connected. There are other features too, but I have them disabled since I don't need them.
-Breaking News, gives you quick, RSS-like US newsfeed from a variety of sources.
-Yelp, one of the very few big name apps available at present, Yelp is fast, informative, and also completely useless because I can do that on my phone better ... but, still cool :D
-Timer, is what is says. Makes up for the lack of a built in timer/stop watch.
-PebbGPS, undeniably one of the coolest apps available. Who hasn't at some point in their childhood wanted a GPS map on their wrist?? It also give turn by turn directions which are actually a lot more useful than the map. It does require a companion app and as with all Pebble apps suffers from Apple's fast app switching ... more on that later.
All in all, these five apps plus built in features like music control, alarms, etc make for the coolest watch I've ever owned. However, I feel that there could be improvement.
First and foremost, fast app switching in iOS cuts off access to companion apps running on the iPhone after a few minutes. Basically, your iPhone puts background apps into sleep mode turning off features like GPS, weather, internet access. This is fantastic normally since it saves you a lot of battery power, but since Pebble relies on either the Pebble app or another companion app to be running in the background, your fancy new watch will stop updating information after 30 minutes or so. Personally I find it wearisome to have to pull out my phone every 30 minutes and reopen the Pebble app and any other companion app I'm trying to use. The worst was PebbGPS which would cutoff all my driving directions every few minutes when I tested it, saying "GPS information is not available" or some such garbage, unless I had my phone unlocked and the PebbGPS companion app open (thus completely voiding the point). ANYWAY I tried playing around with background app refresh and a bunch of other iOS settings without success. LUCKILY THERE IS A SIMPLE FIX, at least for those (like myself) with a jailbroken iPhone, and it's called Background Manager. What this Cydia utility does is let you change the background settings for any single app, or all your apps, so that they will run either in default (fast app switching) mode or forced (fully running) mode. As long as they're in forced mode you can access all information, gps, internet, whatever no matter how long it's been since you actually opened and looked at them. Basically, Background Manager prevents apps from going to sleep and can be configured to work only on Pebble companion apps so the rest of your apps aren't wasting battery power. I would say this is a required accessory to anyone with a Pebble and an iPhone, at least until/if Apple officially fixes this issue. Otherwise, you're stuck opening your phone almost any time you want to get new information on your Pebble.
The next big issue I have with apps is the app store its self. Oh my gosh is it slow. Maybe because I'm using an older phone (iPhone 4S), but seriously, it will drive you nuts. The watch its self is quick and responsive - why oh why is the app so sucky??
And finally, only 8 spots for apps??? There needs to be a way to remove some or all of the 3 factory included watch faces to make room for a couple more apps or custom watch faces.
Design - I've already talked about how good looking it is, but I think it's also worth pointing out that the UI is very well designed too. It's very minimalistic, just up/down forward/back buttons that give you quick access to the information you need. I have to disagree with those who think a touch screen would improve this watch. It's simply too small for fingers, so buttons are much better. Besides that, a touch screen would add zero functionality and probably reduce battery life significantly.
MISSING FEATURES - there are a few things that I sort of assumed would be built in, but are conspicuously lacking.
-timer/stop watch, what kind of watch doesn't have that?? I had to download a 3rd party app to get it, thus taking up one of the limited 8 available spots.
-beep speaker, there is a buzzer but no beeper for alarms and such.
-Notification options, I wish there was a way to change notifications from buzz only to perhaps, LED on a specific color for a specific notification. Also, if in the future they added a beeper, then it could be set to beep instead of buzz/flash LED.
-Volume up/down, for music controls. Currently you can play/pause, skip to next/go back to previous track, but can't control volume. Some 3rd party apps can do this, so why not built in?
-MORE APPS from big names. I'd love to see Facebook, New York Times, Google Maps, Tumblr, etc.
I expect all of this will be available in time. Pebble is still very new and not many people have them. In a way I am reminded of owning my first iPhone back in 2007. Things have gone a long ways since then.
