What is the Future of Mobile App Development? 6 Trends to Watch

The hype around fifth-generation wireless technology (5G) has been building for the better part of a decade, but most carriers only started rolling out 5G access in 2021.

The focus of 5G is speed. It’s not just faster than current 4G technology; it’s exponentially faster, capable of operating at 100 times the speed of most existing networks. This matters because it allows users, from individual people to enterprise networks, to connect with wearables, devices, and machines, in addition to phones. Due to its speed being so much higher, information is transferred in milliseconds, reducing latency and providing a better user experience.

Use cases range from simple to complex. A simple use case might be users watching HD videos on their devices without buffering or quality loss. A study from PwC describes a use case where a 5G-enabled healthcare ecosystem — including apps, internet of things (IoT), and wearables — could allow patients to monitor their health and quality of life better. This could help with identifying diseases earlier and reducing healthcare costs by approximately $2,000 per patient.

Augmented reality (AR) technology imposes artificial images and objects on real-life objects, which is how users can play Pokémon Go while walking around their neighborhood. In contrast, virtual reality (VR) creates an artificial environment. Meta’s Oculus Quest 2, for example, allows users to work out, explore new countries, and watch concerts created in an immersive world—all from their living room. However, AR and VR are no longer solely for gamers; these technologies are rapidly expanding to other industries, including travel, real estate, and retail.

The use of AR technology in the real estate industry is booming, accelerated by an unexpected catalyst: COVID-19. When the pandemic hit, attending open houses in person was no longer a safe option for many. In response, rapid app development helped make virtual at-home walk-throughs possible.

Matterport, a 3D virtual tour platform, created an iOS app in late 2020, allowing home sellers to scan their homes using the LiDAR sensors on their phones or tablets. Previously, that capability was only possible with expensive camera equipment. According to Redfin, a real estate brokerage, 63 percent of buyers who viewed virtual walk-throughs in late 2020 made offers on homes they hadn’t visited in person. Monthly views of 3D walk-throughs via the app were up over 500 percent from February 2020.

Artificial Intelligence (AI) is by no means a new technology in mobile app development, but as AI and machine learning become more sophisticated, so will app capabilities. For example, algorithms can learn from past user behavior with advanced machine learning and then pull data to predict what may happen next.

Where AI could stand out in future app development is facial and speech recognition — biometric markers that can enhance safety features. Companies, especially those in the insurance and financial sectors, can use AI and machine learning not only to improve user safety and data security but also to help spot fraud. McKinsey estimates the potential annual value of AI for global banking at over $1 trillion.

Identifying and preventing fraud will undoubtedly become even more important as more users employ phones and wearables as payment devices. It is estimated that 2.8 billion mobile wallets were in use worldwide in 2020, and that number may rise to 4.8 billion by 2025. As people use those wallets to complete more sophisticated transactions online, fraud detection companies are creating AI-based technology for banks and retailers to help reduce false positives, increase fraud detection, and minimize investigation time.

While the term “blockchain” is most often associated with digital currency, the underlying technology is used in a number of new applications. Simply put, a blockchain is a digital ledger that securely records transactions. Once a transaction is on the blockchain, it’s virtually impossible to alter or remove it. This makes blockchain technology useful for tracking digital assets and securing identities.

Mobile wallets and person-to-person (P2P) payment apps are increasingly using blockchain technology to improve transaction speed and security. It is estimated that 68 million people currently have blockchain wallets. In January 2021, 5.6 million blockchain wallet apps were downloaded.

Because of the added security features, expect to see blockchain technology combined with IoT and smart contracts in the coming years across various industries. For example, working with shipping and logistics companies, IBM found that utilizing blockchain technology helped them reduce costs, improve supply chain inefficiencies, and settle disputes.

Wearables include watches, earbuds, and other smart devices—even certain articles of clothing. Wearables can fulfill a range of functions, from voice activation for phone calls to helping people keep track of the number of steps they take each day. There are approximately one billion connected wearable devices in use worldwide. In 2021, the wearable technology market was valued at approximately $116 billion, with significant growth yet to come. It’s estimated to climb to $265 billion by 2026.

Consumer electronics make up the most significant share of wearables. Still, there’s increasing interest in using them for purposes beyond simple step counting, particularly in healthcare. For example, some wearables, including Fitbit and Apple Watch, have gotten clearance from the U.S. Food and Drug Administration for an electrocardiogram app to monitor heart irregularities.

Other features you can expect to see from wearables in the near future include smart app capabilities tied to security. Recently, Apple teamed up with lock manufacturer Schlage to create smart locks that can be opened using an Apple Watch or iPhone. Users can also add a virtual house key to their mobile smart wallet.

As more personal information goes online, fears around consumer security and privacy are increasing. Consumer data is routinely collected to provide better services, especially in use cases involving AI and machine learning, but consumer concerns about personal information getting out aren’t unfounded.

A recent study of popular Android apps by Synopsis found that 63 percent contained open-source components with known security vulnerabilities. That leaves many consumers exposed to having their information hacked or leaked, which could affect customer experience or confidence in an app.

Two innovations are rising to help resolve security issues such as these. One is biometric authentication, which uses eye, facial, fingerprint, or voice recognition to verify a user. This helps to provide the first line of defense against fraud or stolen information and is easy for consumers to use. The other is the use of distributed ledger technology (DLT), of which blockchain is one part. This technology can help boost IoT security on mobile and other smart devices through additional layers of encryption.
