You'll have to wait until April to pick up an Apple Watch, but the new iOS update has already put the Apple Watch app on your phone. Inside it is an app store you can't see into yet, but here are some current iOS apps that could make the transition to your wrist, making that shiny new gadget and fashion accessory even more valuable.
In 15 states, you can use Postmates to summon a courier to pick up food from restaurants that don't deliver. This ranges from simply getting a burrito from Chipotle to ordering expensive prime rib from a fancy restaurant. An Apple Watch version of this could order your favorite meals in a few taps, or scroll through nearby restaurants precisely using the "crown" (that little wheel) on the side of the watch.
Quickie is an Android and iOS app that launched in January that is similar in many ways to the Apple Watch's own sketch feature. You send either text-based or sketch-based messages, even a collection of quickly-snapped photos, and they disappear a few seconds after they arrive on the other user's phone. In Quickie's case, they are already preparing an Apple Watch and Android Wear version of their app to connect to your phone's contacts, which could mean a more complex and cross-platform competitor to Apple's own product.
Dropcam's Wi-Fi-based camera lets you keep an eye on your home while you're away, and it may be a fit to allow your Apple Watch to look in on your dog, or loved ones, while you're away. As the Dropcam itself is naturally placed to look in one position (it doesn't pivot or move mechanically) you could easily use the "crown" to zoom in and out on specific details in the picture, and, if necessary, choose a different area to focus on using your finger.
You're walking along the street and your phone drops out of your pocket. The screen smashes, leaving the device almost completely useless. iCracked's technicians, who now cover most of the country and launched in London, England, are able to fix broken screens (and other damage to your iPhone) in a cafÃ© or in your home. Potentially, even if your iPhone screen isn't functional, its GPS and data functionality, relayed through a potential watch app, could inform a tech of your location and tell them what's wrong with the phone in a few taps.
The app-automation of Workflow could be a good fit for the small screen of the Apple Watch. Workflow creates a series of tasks (that they call "apps") that your phone carries out. Some, such as making a GIF and messaging it, wouldn't be that useful, but Workflow comes with tasks such as "navigate to nearest coffee shop" and "order Uber to my next appointment." Being able to tap your wrist a few times to make one of these complex actions happen would be a huge boon for those looking to save time.
If you're traveling in a foreign country and have gotten completely lost, or if you just need to know a particular foreign word, the Apple Watch combined with iTranslate could be really valuable. The app already allows you to speak into your phone to ask how to say a particular phrase, and so speaking into your wrist (like a certain legendary detective) to find out how to say something would be a highly valuable addition to the watch. If you're traveling, you could theoretically speak into the watch and have the word you want to say appear so a local passer-by can understand. It's essentially the beginning of a universal translator, like the kind you see on Star Trek and other sci-fi shows. We may not have widely available flying cars or jet packs yet, but in a lot of ways, the future has arrived already.
