Instead of a relatively hollow chamber occupying our wrist-space, Apple's second generation brought GPS tracking and waterproofing to the table. But it's the Activity and Workout apps that are still a staple of your daily exercise.
Essential reading: Apple Watch super guide
That's not to say it's all perfect — issues still remain in software regardless of which Apple Watch model you're rocking — but below is a guide to help you get to grips with what's available right now.
The Activity app
The Activity app is the fitness tracking element of the Apple Watch, and keeps tabs on whether you're getting enough exercise per day.
It differs from most activity trackers by dispensing with step goals, the Apple Watch has three targets: Move, Exercise and Stand. Each target has a ring, which fills to denote your goal process.
The Move ring
The Move goal is effectively your step goal, but measured in active calories. Fill the ring by moving around and elevating your heart rate. This is a sneaky beast, because the Apple Watch will set the target based on your daily averages, so active people will find it tougher to fill the ring than more sedentary types. Our goal on day one with the device was 740 calories per day. Now it's 900.
The Exercise ring
Government guidelines say we should get 30 minutes of exercise per day, and this is the ring to keep you on target. Fear not, anything above a brisk walk is classed as exercise, so take more short walks to hit your goal.
The Stand ring
The Apple Watch hates people who sit down, so you hit this goal by standing up. The good news is that you only need to stand for one minute in an hour to make the Apple Watch happy. Do that for 12 hours in a day, and you've hit the goal. The best thing? The Apple Watch will even bug you to make it happen.
And as of watchOS3, wheelchair users can now also receive 'Time to roll!' reminders in place of Stand reminders.
Each is represented by a coloured wheel, which you need to fill, and the app is accessible from the Apple Watch itself and the iPhone.
Getting set up
When you load the app for the first time you'll be asked to input your vital statistics, which hones the algorithm to your body. If you skipped this step for any reason, you can adjust the settings in the Apple Health section of the Watch app on your iPhone.
After you've filled out the questionnaire, you can change your Move target by long pressing the metric in the Activity app. If you're hitting your goal too easily, or never even close to achieving it, then adapt it to test yourself, but not be unattainable.
Adjust your goals
You can get a progress update at any time by heading to either the Watch app or its iPhone variant. However, you can only see your history within the iPhone app. From there you can see a calendar view of every day, and whether you hit your goal on any given day.
One aspect of the Activity app which is refreshingly good is the Achievements. Accessible on the third tab of the iPhone Activity app, there's 19 achievements to unlock. And they're no walk in the park. Hitting your daily Move goal 1,000 times is one a achievement.
With the introduction of watchOS 3, you can also share your progress with other Apple Watch friends. Working via both the iPhone and Apple Watch, you'll receive progress alerts and the ability to send encouragement (or taunts, if that's your style) throughout the day. This adds a nice social element to help spur you on, which is something that was previously lacking.
The Workout app
While the Activity app attempts to replace your Fitbit (with some degree of success), the Workout app takes aim at your Garmin sports watch. And with GPS now on board, it's now able to at least track outdoor sports accurately – if you're using a Series 2, of course.
The Workout app is accessible from your Watch's home screen, and offers a host of tracked activity. Running, cycling, walking and swimming are all present, as is rowing, indoor cycling, elliptical workouts, stair stepper, and the immensely popular workout sweeping the globe: 'other'. And if you're updated to watchOS 3, the Workout app now features two wheelchair-specific activities.
This was the point where we expected to deliver a host of useful advice about your workouts – but there's precious little to tell.
Get the right stats
If you start a run, cycle or walk you can choose from the Apple Watch whether you want to hit a specific time, number of calories, kilometres, or even just host an open workout. You swipe left or right on the screen to toggle between them.
And for Series 2 users, once you've entered the length of the pool, you can also do the same for your swim.
When you get started, you can still swipe between screens to change the information you see on your run. You can keep tabs on your pace, which is generally always wrong; your distance, which is mostly always wrong; and the total time, which thankfully is always right.
For non-outdoor workouts, it's about the time, your calories and your current heart rate. The confusing part is that it doesn't matter whether you're rowing, stepping or engaging in a sweaty session of 'other', the metrics are the same. To Apple, all your sports are 'other' - although at least with watchOS3 you can now label this broad tier of activity.
Review your data
When you're done, you can review your data in the Activity app on your iPhone. The workout is stored under that day's activity, which is easy to review, but as workouts aren't listed together, it's no-where near as good as a dedicated sports app for comparing sessions or progress over time.
You can review calories (active and resting), time, distance, average pace and average heart rate. You can't see a graph of your pace across the session or a map of where you've been.
