Smartwatch app development trends

The key trend in building solutions such as an Apple watch app or applications for Android wearables is enriching them with more features, especially those that reduce the time it takes to fulfill various tasks.

Smartwatch app development trends

  • Duplication of smartphone functionality

Today, smartwatches can offer practically the same experiences as mobile devices but cost less and often do things faster. For example, you can receive notifications and send messages directly from your smartwatch. Some wearables have YouTube support, while others help users track their physical vitals. There are also devices that can be used for managing smart home systems via special apps.

  • Use of advanced sensors

If you are interested in Apple watch app or Android wearable app development and have already studied apps available today, you’ve probably noticed there are a lot of solutions pitched to the healthcare and sports industries. Thanks to the sensors featured in these devices, applications can get access to data such as heart rate, blood oxygen level, respiration rate, etc.

Many are enriched with new sensors that are much “smarter” than what was available just a few years ago. Now sensors are not only able to pass signals but may also be able to process them. Some are even AI-powered. This means that some sensitive information can be analyzed directly by sensors without the necessity to transfer it to other system components.

Engineers are also working at making sensors more power-efficient; some models can use solar energy to function.

  • Voice commands and gestures

The screens of wearables are usually significantly smaller than smartphone screens. That's why, quite often, it’s not easy to design easy interactions. Developers need to look for better variations. In many cases, gestures and voice commands are an excellent alternative to traditional interactions via taps and button presses. Though gesture control isn’t new, it’s much more powerful and advanced today. For example, there are apps on smartwatches that allow users to execute remote control over smart TV or other devices with the help of voice commands and gestures.  

  • Implementation of AI

The use of AI capabilities in software solutions has become one of the most popular trends. In smartwatch app development, AI features can be used to provide recommendations to users, create personalized content (for example, meditation plans or training sessions), as well as analyze collected data.  

How to build a smartwatch app

Wearable app development involves several important steps that will help you to create a fully functional app.

  • Planning

At this stage, you should develop a full vision of your product. You need to understand what tasks users will solve with your app, and how they will interact with it. It is also necessary to decide how the app on wearable devices will be connected to smartphones or other smart devices.

  • Design

Based on your requirements, designers will create prototypes or wireframes of interfaces. Here, designers will face difficulties related to the fact that smartwatches have rather small screens. It will be vital to make sure that the interface is convenient for users to communicate with your app and fulfill the set tasks.

  • Development

This step includes a lot of coding processes. For building smartwatch apps, developers usually use programming languages such as Swift, Kotlin, and Java. As for frameworks, watchOS and WearOS are among the most popular choices.

  • Testing

This is a very important stage within every Apple Watch app or Android wear app development project. The first tests are often conducted in parallel with development. For the development team, it is very important to find and fix all bugs before the app is released. In apps for wearables, it is crucial to check the compatibility of the app with different devices as well as the correctness of data exchange with smartphones.

  • Release

Once everything is properly checked, it’s time to make an application publicly available. Apps for wearables are usually shared via app marketplaces. For getting approval and publishing your application on an app store, your solution needs to meet the requirements of the platform. We also recommend careful attention to your app description on the stores and ways of promoting it via different channels for ensuring the highest possible visibility among your target audience.

Common wearable app development challenges

The process of building any type of software, including an Android Wear or Apple Watch app, is always associated with a variety of potential risks. But being aware of the challenges will make you better prepared to deal with them. Familiarizing yourself with the list below will help you avoid serious problems on the way to realizing your project.

Common wearable app development challenges

  • Battery issues. With the progress made in smartwatch development, wearable devices are becoming more lightweight and compact. The dimensions of such devices make it impossible to install huge, powerful batteries. So developers need to find the right balance between the functionality of the app and the battery resources required.
  • Compatibility. Though some companies prefer to launch solutions for one OS only, given the variety of wearables today, it’s better to offer support for multiple platforms. In reality, it can be rather complicated to ensure that an app performs seamlessly on different devices. To reach this goal it’s recommended to tie a wearable app to a vendor-independent platform.
  • Functionality and user-friendliness. While there is a clear desire to enrich an app with as many features as possible, it’s important to make sure interacting with it will be convenient for users and easy to understand.

One project of this type was an iOS application for Emergency Watch that allows users to trigger an alarm in practically no time when an emergency arises. This wristwatch was designed by Montresa for elderly people and users of all ages who want to feel safe and protected regardless of their location. 

Smartwatch app development

The watch has only one button, but there are different scenarios for a single-tap, double-tap, and long-press. Instead of using a smartphone to contact someone in an emergency, a person can use the watch to send an email with coordinates or call an emergency contact. It is also possible to send a command to a smartphone that will play a loud, siren-like sound that can scare off attackers or thieves, or help to find a lost mobile device. The app was fully built and well-tested within just 1.5 months.
