The wearable apps market is still nascent. Hence there’s a fair chance that your application will make a hit. If you’re a business owner looking to make a smartwatch app, this blog will tell you everything you need to know about it, including whether you should make a Wear OS app or opt for an Apple Watch solution instead.

Without further ado, here’s how you create a wearable app that customers will love.

Key Takeaways:

  • No reason to consider Google’s Wear OS and other smartwatch brands. Their market share is miserable, and Google has just teamed up with Samsung to create a new OS for wearables.
  • The Apple Watch dominates the smartwatch market. Therefore, focus on wearable devices app development for watchOS.
  • When you build a watchOS application for the Apple Watch, rely on Apple’s native development tools like Xcode and SwiftUI to create genuinely immersive experiences.
  • Today, you can architect an Apple Watch app as a stand-alone mobile product that customers will discover in the App Store on the smartwatch itself. No need to create a governing iPhone application like before.

Wearable Apps Market Overview

Let’s face it, when we talk about the market of wearable apps, it’s mostly Apple Watch software. The Cupertino company has sold over 100 million smartwatches since 2015, maintaining around 55% market share today.

There’s an extremely slim chance you’d consider developing wearable apps for smartwatches produced by other companies:

  • Samsung
  • Fitbit
  • Garmin
  • other small manufacturers

Here’s why I think you shouldn’t contemplate developing a smartwatch application for these gadgets. Google has recently bought Fitbit and then partnered with Samsung to collaborate on a more advanced OS for wearables. The new OS will replace Google’s Wear OS and Samsung’s Tizen.

This new wearable OS by Google and Samsung is still a work in progress. Moreover, it’s unclear whether their new hardware will support existing wearable software developed for Wear OS.

Then, Garmin is kind of a thing in itself. Their hardware is very niche, targeting professional users, and their platform doesn’t offer much room for developers’ creativity.

I’d say Apple pretty much owns this market at the moment. Therefore, the Apple Watch is the most lucrative option for wearable device app development companies, and you can safely cross off from your agenda questions like, “How to make an Android Wear app?”

Types of wearable apps

If we look beyond smartwatches for other wearables (a space that’s quickly exploding), we’re bound to bump into these options:

  • create wearable applications for controlling portable Internet-of-Things gadgets
  • build wearable applications for healthcare sensors and fitness trackers

So in this blog, we won’t talk about abstract smart watch app development. Instead, I’ll mainly focus on giving you the details on developing watchOS apps.

Wearable Apps Use Cases

What are the primary use cases for wearable software? A smartwatch is probably the most personal piece of electronics people wear. It behooves business owners to take full advantage of this fact.

If you meditate on the different kinds of wearable applications that make sense developing, you’ll probably come up with these three categories.

Health and fitness

A smartwatch solution is a perfect companion for reminding patients about taking meds or notifying them about vitals when they need attention. Because a watch is always with them, they will hardly ever miss a notification.

A wearable app can silently gather user data throughout the day, using built-in sensors or communicating with another wearable device, and then bring up highlights as users get ready to wind down.

And, of course, it’s hard to overestimate the comfort of having a personal fitness trainer on your wrist, especially when they can accurately track your body movements and other critical data, e.g., heart rate.

Everyday customer apps

Another large category of wearable applications is everyday utilities like timers, weather apps, converters, and virtually any tool customers can quickly use to complete simple actions.

Enterprise use cases

I bet quite a few companies are looking for answers to “How to create a wearable or watchOS app?” because the automation this platform unlocks can streamline so many workflows.

Such mobile products can help workers quickly find their way around, track their performance, simplify inter-department communications, deliver tasks, and so much more.

5 Steps for Creating an App for Wearable Tech

Now let’s take you through all the steps of wearable application development. Note that most of these steps apply to building wearable apps for watchOS. If, despite all advice, you still want to build an Android Wear app, check out this guide by Google.

Step #1: Get the basics right

Before you start to develop a wearable app, you need to decide on two major things:

  1. whether you want to create a wearable app using an application builder or native development tools
  2. whether your Apple Watch app will be a companion to an iPhone app or a standalone application

Native vs. app builders

I strongly recommend you choose a native development environment and tools for making a smartphone solution. Most app builders lag in terms of functionality and flexibility and do not support the latest features available in new hardware.

For example, by building an Apple Watch application with Apple’s SwiftUI, you can reuse code on any Apple platform: iOS, iPadOS, TV OS, and macOS.

Moreover, complications — the latest feature in the Apple Watch that makes glimpses of your mobile product available on the main watch screen — can be developed only in SwiftUI. For instance, everything besides the clock on the following screens is complications. Wearable app developers can make such complications available to customers (outside of primary smartwatch apps) by using SwiftUI:

Companion vs. standalone

Since Apple Watch Series 6, we can make a wearable app that works independently from an iPhone big-brother app. Previously, smartwatch software had to rely on the iPhone to download data, use location services, and perform other advanced actions.

As for independent applications, users can discover and download them from the Apple Watch app store. The most significant advantage of Apple Watch-only apps is that they directly access all hardware features of the smartwatch, including internet connection, etc.

A companion app may work when you have a main iPhone application and only plan to provide glimpses of information to the user via a smartphone app.

Step #2: Design a miniature UX

The first thing to remember when you’re creating an app for wearable tech is screen size limitations. So don’t assume you need to cram the content from a regular smartphone application to a tiny smartwatch screen. Instead, focus on creating a unique, glanceable user experience.

Most gestures from the iPhone and long presses are not supported, so think through your app in a way that users don’t have to swipe between screens endlessly.

By the way, in the latest version of watchOS, you can add a “More” button where you can hide settings or other secondary options.

Here are some more tips on designing a winning UX/UI for the Apple Watch:

  • any data you display must be glanceable and actionable
  • allow users to perform one single action on every screen
  • use Sort and Filter pickers to trim down long lists of items
  • use a swipe to delete gesture to enable users to remove stuff quickly
  • add a button that applies to all content displayed on a screen at the top (users can pull it down when they scroll to the very top of a list; same as when you pull to refresh a Twitter feed)

Note on prototyping. I wouldn’t recommend creating a clickable prototype for an Apple Watch app simply because a prototype and a real-life smartwatch solution work differently.

The thing with small screens is that an app’s appeal is not so much about a pleasing user interface as it’s about UX (correct combination of screens and arrangement of visual elements on each screen).

Step #3: Build features

To make a watchOS app, you need to code its features. That’s precisely what you do once the design is ready. As I already mentioned, I advise you to use Apple’s native tools for smartwatch app development, specifically SwiftUI (which comes with XCode).

That will guarantee easier maintenance and future upgrades and give you some insights into the development process. You can ask developers to record their screens while they build an Apple Watch application, and you’ll see the app screens in action.

Ok, speaking of features. What functionality should you develop? It depends on the type of smartwatch software you envision. Still, I suggest you make the most of the smartwatch’s built-in capabilities:


If you want to create a watchOS app to help patients monitor their health, take advantage of these sensors: electrical heart sensor (ECG), blood oxygen sensor, optical heart sensor, accelerometer, gyroscope, and GymKit (if you plan to sync data with a proprietary sports equipment).

Motion sensing

HealthKit supports Mobility Metrics that collect data on how the person moves. You can use this data in your apps, say if you want to help patients recover from a musculoskeletal injury.

You can also make use of CareKit, for example, to sync user-submitted data with a cloud.

Location awareness

You can add GPS capabilities to your Apple Watch application and even display rudimentary maps in the app to help users navigate if necessary.

Audio/video streaming

Not sure if video streaming makes a lot of sense for a wrist-worn app, but you can benefit from the ability to stream audio, for example, as instructions to a workout.

If you enable Siri shortcuts for your Apple Watch software, users will have an easy time accessing the app’s features.


This one is simple — don’t overuse them.

In-app purchases

Note that you can sell digital content directly on your smartwatch application using in-app purchases (will require StoreKit integration).

Step #4: Test

What do we do before we make the app available to the public? That’s right; we test it.

The reality is testing without an actual device is hard when you create an Apple Watch app. Quite often, that’s the case because you need to check how it performs on its own and verify that the product syncs data correctly with an iPhone application, a cloud solution, or a smart gadget.

One way around is automatic tests written by developers as they develop an Apple Watch app. Such automated tests will help prevent most crashes even before starting unit testing.

You can also use the Simulator application built into Xcode to run your smartwatch software virtually.

Step #5: Distribute

Apple Watch apps have their mobile store that customers can access on their wrists. However, the submission process is similar to regular iOS software distribution, with a small caveat. When submitting, you will be submitting an iOS app with details filled only for the Watch App card. Well, your dev team should be able to figure this out.

Check out how an entry looks in a wrist-borne App Store and make a note of the content scarcity.

You can also use an ad hoc distribution model if you want your solution to work only for specific users, e.g., if you decide to track employee navigation inside a facility to identify where they spend most of their time.

Wearable App Development Best Practices

Here are some additional tips that will help you get better traction with your wearable app, especially when custom developing the app

  • use universal links to display content (that’s easy to update on the web) in your smartwatch application or when you need to link between different smartwatch solutions.
  • mind how you treat the smartwatch’s storage; cache only stuff that needs to be displayed to the user immediately; remove content (e.g., songs) that customers rarely use.
  • SiriKit will allow you to add Siri shortcuts to quick actions in your application and show them in Siri Watchface, where they pop based on when the user is likely to need them.

  • sparingly rely on internet connectivity; trying to connect for an extended period will quickly wear down the watch’s battery.
  • delegate complex computing tasks to the cloud, and the watch application can fetch ready data afterward.

How Much Does It Cost to Develop a Wearable App

Depending on an app’s complexity, it may take between $30,000 and $70,000 for a wearable application development company to create such a solution. Of course, if you envision a product with just one or two screens, the app development cost will be closer to the lower end.

As you can see, wearables app development is quite tricky, and its investment requirements are on par with iPhone and Android development services just as is the case when building a fitness tracker app. So tread with care.
