Extending iMessage

The Message app is the most used application on iOS. This isn't really a surprise when one thinks about how people use their phones, but it does identify an area that the developer community hasn't been able to tap into despite users spending a great deal of their time there. For someone like me, it was difficult to imagine that there really was anything that developers could do with iMessage, as my use case is just sending images, videos, and text in the same way that you could with SMS and MMS. Of course, I make use of some other convenient features like group chats, read receipts, etc, but none of these areas seemed to present a way for third party developers to add value. Of course, that's when I think about how I use messaging, but there's a whole world of messaging beyond the most basic functionality that SMS and iMessage provide. Apple is tapping into those ideas for iMessage in iOS 10, and they're bringing developers along for the ride.

Apple has taken a two pronged approach to upgrading iMessage in iOS 10. The first are the features that come by default, the features that are part of iMessage itself. I actually covered some of these in my macOS Sierra preview, although in a limited manner as macOS Sierra is not capable of using most of the new features itself and is just able to receive messages that use them. The two main features added to iMessage by default in iOS 10 are message effects and Digital Touch messages.

Message effects work as you'd expect, with animations that can be applied to the actual message bubble itself or as an effect that plays in the background behind the scrolling list of messages. For bubble effects Apple provides an invisible ink effect that requires you to swipe across the message to reveal it, a gentle effect with tiny text, a loud effect which enlarges the bubble for a moment when it's viewed, and a slam effect which crashes the message into the screen, complete with dust effects as it touches down. As for screen effects, you have balloons, confetti, lasers, fireworks, and a shooting star. There's not a whole lot else to say about message effects, as other messaging apps have implemented these features before. If you're a fan of them then you'll be happy to see them brought to iMessage, and if you're not you'll just have to hope all your contacts feel the same way.

Anyone who has used an Apple Watch will be familiar with Digital Touch. In this case it has been modified since you're using it from an iPhone instead of a watch, and the list of things you can send have been expanded as well. To bring up Digital Touch you simply tap the icon with two fingers on a heart which sits next to the text entry field. Once you do so you'll be presented with a condensed version of the Digital Touch UI in the space where the keyboard would normally be. This UI works in a similar manner for iMessage apps, although I'll touch on that more in a bit. 

In the condensed UI there's a small drawing canvas where you can perform Digital Touch actions. On the left side you have a button that allows you to change the color of the pen used when drawing, and below that is a camera button which expands the UI and allows you to draw on top of a photo taken with the camera.

The expanded UI will first show a preview of all the actions you can perform. These all work in the condensed UI as well, but you may not know about all of them until you bring up the expanded version as the condensed view only shows three actions on the right side and switches between two sets every few sections to show all six. To be honest, the Digital Touch interface is kind of confusing, and I wouldn't be surprised if it receives some tweaks in future minor updates to iOS 10. I'm don't really much value in Digital Touch on the iPhone either, especially since actions like tapping don't translate well from the Apple Watch where it would actually trigger the Taptic Engine to simulate your wrist being tapped.

The second side of the iMessage improvements is the creation of a developer ecosystem centered around iMessage. This API will allow developers to create their own mini-applications that run inside of iMessage. This really covers three types of applications, the first of which being sticker packs, the second being interactive messages, and the third being other types of apps that work with media. You can see an example above of the new Super Mario Run sticker pack which is available in the iMessage app store. Interactive messages cover applications that send messages with content which can then be opened by the receiving user in the corresponding application. Apple's example was sending a message with the menu for a party being planned, which can then be modified and commented on by the receivers. Finally, the other category of app is for working with media, and an obvious example is implementing a GIF application for sourcing reaction images in the iMessage app itself.

I'm not really someone who makes heavy use of emoji or effects in message apps, and so I don't have a whole lot else to say about the changes Apple has made to iMessage in iOS 10. However, the popularity of these features in other messaging apps makes it clear that many users value these capabilities, and so it makes perfect sense for Apple to bring them to iMessage. Most interesting for me is the idea of the iMessage App Store, and whether or not it's going to be possible to monetize applications like sticker packs. Line has already shown that people will pay money for such things, but that relies on developers not rapidly creating a race to the bottom for prices, which is what has happened in the iOS App Store to an extent. Like many of the new technologies that Apple introduces in new versions of iOS, only time will tell how things play out.

    How about battery life across different iOS ? has it improved/degraded or is +/- same compared to ios 9 ?
  • lilmoe - Tuesday, September 13, 2016 - link

    I previously thought that the increase in battery life of the new models were a direct result of processor improvements. But they're probably more a direct result of the increase in battery capacity. If so, then you should expect slightly less battery life on iOS 10 for the older models.

    That being said, things might even out because it looks like they've improved their view rendering so that the processor doesn't need to work as often, but this might impact RAM management in which other parts would need to reload more often.

    But what do I know. I usually go to Anandtech to check out actual tests for these things... oh wait...

    Best iOS 10 review i have seen so far. Learned alot of new things too. Thank you!

    Apparently installing iOS 10 via the OTA is failing on a myriad of devices, causing them to need to be restored via iTunes. Apple is recommending at the moment to only install the update via iTunes.

    Also be sure to backup your device before attempting to update.

    Unfortunately it goes without saying these days that I never install an OS update on the day of release. Not for iOS, macOS, Windows, Android, my TV, my PVR, my NAS, my router etc etc (I probably forgot a bunch of devices)
    I lived with all of them up until now, it's no problem to wait a day or two for the inevitable bug fixes.

    @colonelclaw: Agreed. But not in every case. At one site, a Cisco router (enterprise grade, not consumer), running an old ios, and its HSRP partner is running the new v15 ios. The old ios router was constantly hacked, even with the strongest, most random password possible, and even with in-bound access lists bound to the VTY lines. It was really quite annoying. They were probing the network, and I could see the failed login attempts on other switches and even the Wireless Access Points. The v15 router stood up to the hack, the whole time.

    Sometimes updates are really useful...

    Apple says this has been fixed. Still, I never install major updates over-the-air. I always connect to iTunes for anything beyond a bug fix point release.
  • Donkey2008 - Tuesday, September 13, 2016 - link

    I did OTA upgrades to iOS 10 on both an iPhone 6 and an iPad Air at 11am PST this morning. Zero issues. Just sayin.
