Rethinking watchOS

watchOS 1 was good as a first attempt at creating an operating system for smartwatches, especially when one considers that the idea of what a smartwatch is was still up in the air at that time. However, there were obvious issues with the interface, and when I think about the changes that Apple has made since that time it’s apparent to me that these issues stemmed from that unsureness about what would actually define smartwatches as a product. watchOS 2 didn’t really make many big improvements to the overall UI and interaction model on the Apple Watch. It only came out around half a year after the launch of watchOS 1, and much of the focus was on fixing the really serious flaws in the operating system, as well as deploying the WatchKit API so developers could design applications that actually run on the Apple Watch's hardware instead of remotely on the paired iPhone.

With watchOS 3, Apple is taking the opportunity to re-evaluate initial decisions made about how watchOS works. After one and a half years since of the Apple Watch being in the hands of consumers, there’s a better understanding of how users actually use smartwatches. It turns out that some of the big features that Apple advertised with the original Apple Watch have basically gone unused, and have been de-emphasized in the operating system as a result. In doing so, Apple has opened up parts of the interface for new features to be added based on what features users actually do utilize.

When upgrading to watchOS 3 or starting up a new Apple Watch, the interface looks just like watchOS 1 and 2. However, there are some obvious changes that Apple has made, starting with the addition of new watch faces and complications. There are two new Activity watch faces, along with a Minnie Mouse watch face to complement the existing Mickey Mouse face, and a new minimalistic watch face called Numerals. Apple has also made it easy to switch between watch faces by swiping from the edges of the display. I’ve found this to be quite useful, as I like having the Activity Digital face available, but it’s quite dense with information so I often use the Numerals watch face and swipe over to Activity in a situation where it’s more relevant. This wouldn’t be feasible with the previous model of force touching the display and swiping over to another face, which still exists but is really only useful to access the customization options for each face.

Beyond the watch faces, users will notice changes when they first try to open the old glances screen or the friends screen that was triggered by the pill-shaped button on the side of the case. Both of these functions no longer exist in their original form. In the case of the friend screen, you can now send messages and use Digital Touch to communicate with anyone via the Messages app. This definitely makes it more difficult to access these features compared to before where it was a single button press away, but in my experience the only time I ever saw that screen was by accident when the watch failed to recognize my double tap on the side button to access Apple Pay.

As for glances, the screen has been removed from the operating system, but the core idea lives on in another form. In theory, glances provided a way to quickly access relevant information from applications. In practice, they often ended up being a strange middle point between the concept of a complication and a full blown app. In some situations, they would display information relevant to the current context, like the current song in the now playing glance, or the weather in the weather glance, and you could tap them to open their associated application. Others like the heart rate glance didn’t have any associated application, and basically acted like an application that was only accessible from the glances screen. There was also the issue of applications not being loaded when tapping on a glance, which would lead to a huge delay and sometimes a loss of context when the application finally loaded.

watchOS 3 introduces a new app caching model that makes glances obsolete for the most part. However, it’s still necessary to have a way to quickly access commonly used applications. To solve this problem, Apple has introduced a new app switcher called the Dock which can be accessed using the pill-shaped button that was previously used to access the friend screen. This screen can have up to ten applications which are selected by the user, plus one slot for the most recently used application that isn’t pinned in the list. These applications are kept cached in memory, which means they can be rapidly resumed when opened. This provides quick access to common applications, while also solving many of the issues that the Apple Watch has had with long app load times. In general, you’ll only use a small number of Apple Watch applications frequently, and being able to keep ten of them cached in memory with near-instant loading alleviates the load time issues for those key applications.

With Glances gone, Apple was able to make a new screen accessible by swiping up on a watch face. The new screen is essentially a version of Control Center for watchOS, and it expands upon a similar feature that existed in the Glances screen in previous versions of watchOS. By implementing the screen more like an application and less like a glance, Apple is able to add more functionality by making it a scrollable layout. There’s now a view that displays the current battery level, which is useful now that there’s no Glance to provide the same information. There’s also a button to manually lock the watch, and on the Series 2 a button that is used to eject water from the casing via the speaker after the watch has been submerged.

Pressing the Digital Crown still brings you to the Carousel screen, but as I mentioned above, the Dock provides access to most of the apps that a person uses frequently, so it’s not often that one has to go to the Carousel and try to tap on tiny icons to open apps. With that in mind, it is kind of odd that the button which is most analogous to the iPhone’s home button brings you to a screen that you rarely want to go to, but I suppose that the removal of the friend screen meant that putting the Dock in its place was the most reasonable decision rather than also changing how Carousel is accessed just so the Dock would be tied to the Digital Crown.

In general, the new application caching in watchOS 3 has made applications genuinely useful where they weren’t previously simply due to long load times or issues with the app never loading at all. The improvements made to the SiP in Series 2 also play a large role in speeding up app load times when apps aren’t cached in memory. However, as someone who used the original Apple Watch on watchOS 1 and 2, the awful performance back then has essentially conditioned me to not use applications on the watch, and I’ve had to actively think about using the apps on the watch now that they’re actually reliable. This won’t be an issue for new adopters, but I think anyone who is familiar with the original app experience on the Apple Watch will have the same aversion to using the apps that I do. In that sense, it’s important for Apple to maintain the quality of the user experience in order to mend the trust of users who were turned away by the problems that existed in the past.

    You didn't mention anything about the Apple Watch Series 1 (original watch with S2 SiP)

    Where is the kiss-ass Macbook Pro review?
    Apple has "fixed" the battery problems, now update your results and praise the gods. (I know Anandtech can't do a "bad" Apple product review ;)

    On a more serious note, please do a battery life comparison between 13" non-touch vs 13" touch bar, I want to see the battery hit and the performance trade off. I don't care if it only lasts 3 hours, or breath-taking break through (30% improvement aka 4h), I just want to know the trade off (in relative terms) so I know what I'm buying into. I'm sure there are many people in the same boat.

    Oh no, Consumer Report got bought by M$ and/Google too.

    Man, the "whole world" is picking against the "underdog", Apple T_T
    Don't worry, Anandtech is here to kiss ass and save the day ;) There are not enough money in the world that M$ and Google can spend to persuade Anandtech.

    Jokes aside, can we expect Macbook Pro reviews coming soon? Please...
    Christmas gift?

    I have to buy Mac, because I need xcode to write iOS apps.
    Don't want to deal with linux, I don't have the time and energy.

    A lot of commenters dissing smartwatches should use a smartwatch for a few weeks before commenting. I know because I thought wearables were pointless until I got a Pebble. Now I can't ever go back to a normal dumb watch. It was a revelation to have a tiny computer strapped with so many apps strapped to my wrist. The Apple Watch is even more amazing because of the deep iPhone integration and its sensor suite.

    And lastly, RIP Pebble, I hope the tech lives on somehow. I'll be using mine until it stops working. The always-on LCD makes it feel like a normal watch yet I can get by with charging it every 4-5 days, not like the daily charging needed by other smartwatches. Maybe Apple needs to have an always-on OLED screen like with Nokia's Sleeping Screen app on Symbian.

    smartwatch is dead anyway

    Simply: Another useless product that needs constant charging.
    If you have money and want something big on your arm, buy a Swiss made watch, at least you look good with that on!

    I don't know. at some point folks, producers and consumers, will have to admit that the limiting point of all portable devices (watches, phones, laptops, etc.) is power. and there hasn't been a meaningful increment (much less a doubling) in power density in a battery in decades. until someone is smart enough to invent a new atom, the wall is staring you in the face. controlling a chip as node size shrinks, while reducing power demand by a bit, will in and of itself demand more circuits and power. WYSIWYG.

    So... What's different?
  • amdwilliam1985 - Thursday, December 22, 2016 - link

    Everything is different, the world has been turned upside down if you're an Apple fans.
    If you're not, then move on along, nothing much to see here.
