Mobile Software Development Trends To Know In 2021

As an answer to the digital era we are all in, the mobile app development industry is evolving with lightning speed. In order to survive, many companies decide to create their own trending mobile solutions since consumers show growing interest in making purchases on mobile devices.

By the year 2021, mobile app market revenue is expected to reach a whopping $693 billion.

However, not everything is as good as it seems. According to Gartner, only 0,01% of mobile applications actually succeed, which is not comforting. In this post, we will take a look at the latest trends in mobile software development, so you can ensure your next app is one from 9,999 that turns out to be a hit.

The evolution of mobile applications

Before we proceed to the current state of mobile solutions, it is important to mention how far it has come. Starting from 2005, websites started to be designed for smaller displays and equipped with touchscreen-friendly interfaces. A couple of years later, the development of native applications with gesture navigation had begun as businesses recognized the advantages of having a dedicated mobile solution.

Around 2013, the popularity of mobile web applications had risen. Websites were now capable of being accessed through a device’s browser. What is more, context-aware technology was introduced - apps gained user context like location, time and pattern identification for a more personalized experience. Mobile web apps evolved into hybrid apps and were wrapped inside a native container providing access to native platform features. This led to an increased interest in voice technology as a way to simplify human to machine interactions.

Since 2019 we have been living in an era of micro apps, which are consumer-oriented solutions that deliver highly targeted functionalities and personalized experiences with the help of artificial intelligence.


State of mobile application development in 2021

It is no news that people spend more time on mobile devices than ever. Statistically, more people own a cell phone than a toothbrush. 70% of traffic is generated by mobile devices and around 75% of emails are being opened on mobile devices. The ease of use and convenience of mobile devices changed user’s behaviour. According to Google, 80% of smartphone users are more likely to purchase from companies with mobile apps.

Statista goes further and states that by 2022, App Store user spend will increase to $157 billion (up by 92%). In 2021, the mobile market is set to grow by 385% and there will be about $7 billion mobile users worldwide.

However, in this dynamic and ever-evolving environment apps that shined in 2020 may not have the same success factor in 2021. That is why you should incorporate the latest trends into your development strategy.

Top trends in mobile development in 2021

Mobile trends just like any other trends are everchanging. To get ahead of the competition in the mobile app development world it is crucial to analyze those trends and adapt accordingly. Some of them have been present for some time now, while others are the latest finds addressing the needs of consumers in 2021.


Cloud-native applications are apps with code written with a cloud-first approach, meaning the need to have a separate server for hosting. In the case of those apps, everything else is handled by the cloud-native solution providers like AWS, Google Cloud or Azure.


Cloud-native provides many benefits for developers and businesses like the fact that Google Cloud serverless tooling allows automatic scaling depending on the website traffic.

Internet of Things

By 2022 the IoT market in the US is expected to exceed $500 billion and a great part of this share will be the consumer electronics segment. This technology is impacting how people interact with each other and live in their homes by providing opportunities for users to engage with appliances and gadgets in real-time. The most prominent field of IoT’s impact will be smart homes since more and more smartphone users control their home devices with apps. Forecasts say that by 2030 there will be around 50 billion of these IoT devices used around the world creating a massive web of interconnected devices.


What is more, IoT has the potential for data sharing, which will definitely draw the attention of the app industry.

Mobile wallets


Mobile wallets have gained popularity among users, especially since economies of different countries are turning digital. People prefer using mobile wallets like Google Pay, Apple Pay, Amazon Pay etc. to cash or providing card details for even faster transactions. As the market is not yet saturated enough there is still potential for growth in the future. For mobile wallets the future trends include:

  • audio-based mobile wallets
  • near-field communication (NFC) based payments
  • radio-frequency identification payments

Artificial Intelligence and Machine Learning

AI and ML have already started taking their place in mobile applications and devices. Some examples of those include chatbots, facial recognition or voice search. There are also AI-powered apps for photo edits taking the technology to the next level. In the near future, AI-based cameras, user predictions or voice translations will be even more common in smartphones.


The future of AI includes:

  • image recognition, classification and tagging
  • object identification, detection, classification and tracking
  • processing of patient data
  • predictive maintenance
  • automated geophysical feature detection

Combining AI with ML will be super useful in developing mobile apps as it can learn from the previous development process to detect problems and fix them.


Even though modern chatbots are far from being perfect, they are slowly creeping their way into our everyday lives. They help to automate repetitive user interactions answering simple questions like is the store open or aiding in the ordering process. What is more, more than 50% of buyers claim they want more self-serving customer service tools and chatbots are great ways to achieve it. An example of such a solution can be an app from Starbucks - ‘My Starbucks Barista’ in which you can tell the app the type of beverage you want and it places an order for you.


Statistically speaking, 36% of Americans claim to have used a chatbot and with the popularity of Facebook Messenger, the usage of chatbots on mobile is rising even more.

Biometric authentication

All mobile apps should think about implementing some sort of biometric authentication. Fingerprint scanning and face unlock are great way to ensure data security. Apart from them there also is iris scanning, voice or hand geometry recognition to think about.


In the future, we will be able to see new trends in biometric authentication including:

  • immigration services
  • cloud-based biometric solution
  • online banking and mobile payments

Beacon technology

Bluetooth Low Energy (BLE) signals are what powers Beacon Technology. It allows, for example, to locate a store selling a specific product through a mobile application. Phones are able to receive signal and provide relevant information and guidance for users. This technology has great potential in the marketing industry as it can reduce the bridge between users and companies. It is slowly being implemented in hotels, healthcare institutions, museums etc.


Virtual events streaming

Virtual events have become popular amid the Covid-19 pandemic as people were not able to attend events in person. However, even in the post-pandemic world, virtual events present whole new opportunities, making them less exclusive and increasing availability for people from all around the world.


One of the most popular online events platform Hopin allows to change rooms, listen to different speakers as well as communicate with other participants. In 2021 we will most likely see more of such platforms coming into life.

Augmented Reality

Augmented reality will continue trending in 2021. Mobile apps can use AR features for a wide range of features. Starting from the hit game Pokemon Go AR changed mobile gaming and today, more applications are using in for more practical features.


Apple Watch is probably the most popular wearable device that changed the game for everybody. Apple dominated the smartwatch market with features like ECG or blood oxygen levels measurements. In 2017, there were around 453 million connected wearable devices and according to ReportLinker, the wearables market is expected to grow beyond $24 billion by 2023.

With technological advancements, we should expect wearable applications to become a vital part of our everyday life as more and more smartwatches start operating independently from phones.

5G tech

The introduction of 5G technology certainly has an impact on mobile development trends. The number of 5G connections is rising all around the world and it will change the way apps are created and used. The significant speed improvements brought by 5G increases the functionalities of mobile apps as it allows up to 1 million devices per square kilometre to connect. This can lead to the realization of the idea of everything being connected including cars, washing machines, fridges or security cameras.


Smartphones revolutionized the way we shop, make payments or look for information. Mobile app stores are full of applications for various purposes yet the market still seems not saturated enough. With all these mobile application development trends, the app industry will continue to grow with great speed.

To stand out in this highly competitive market it is important that business leaders create solutions that are aligned with the newest trends and use the latest technologies. This all can be achieved with an experienced development team that is able to create a fresh product with the best tools available.
