mobile app development

We gathered eight key mobile app development trends for you to keep in mind in 2021. This article is meant to bring you to a deeper understanding of the rapid shift to a mobile-first lifestyle, as well as help you make sure you know what to expect from mobile users in the new year. 

Wearable App Development 

Portable and wearable technologies have expanded significantly in the market over the past few years and are expected to grow further over the next year: it is noted that wearable technology has grown by 15% over the past 4 years. Smartwatches, health monitors, and training straps are the most popular wearables. Therefore, developing applications that interact with portable and wearable devices through smartphones can drive your business growth.

Moreover, the Covid-19 pandemic has shown us that HealthTech is what we need more than ever, and our future is closely tied to remote patient monitoring. Doctors can continuously monitor patients with chronic conditions who use wearable medical devices. 

Interestingly, wearable technologies are now less focused on fitness trackers and serve more as fashion statements as well. Wearables become more attractive to wider audiences, and so we need to follow the mobile app trends and consider integrating apps with wearables in 2021. 


This year’s pandemic has forever changed our shopping behavior towards e-commerce. Those businesses that relied on their offline retailing model were suddenly forced to either adapt (and go online) or shut down. 

Mobile commerce (also called m-commerce) refers to any money transaction made through mobile devices and is really booming today. The growing demand for online shopping has made the mobile commerce trend a must-have for online marketers. 

Thus, by using a mobile commerce app it is possible to reach a large audience. According to BigCommerce, mobile e-commerce sales should account for 54% of all e-commerce sales by 2021. 

Mobile Wallets

What usually lies in your pocket – your wallet – still hasn’t changed. But the wallet of the future will be your mobile phone, and that future begins right now with many mobile wallets already available worldwide. Therefore, mobile app developers should strive to improve their current versions in order to stand out.

One of the most developed mobile wallet markets is in China, where not only the upper and middle-class people actively use mobile wallets for everyday purchases, but even lower-class citizens often use the famous WeChat app to do money transfers.  

It is important to mention that mobile developers should plan to add mobile payment capabilities to their tools. There is Apple Pay, but it’s not the only platform in the growing mobile payment market now. When something gets more popular, the importance of enhancement features and capabilities increases. For example, mobile app developers must consider adding elements such as biometric and multi-factor user authentication to their apps. 

Internet Of Things (IoT) 

It is wise to introduce IoT as the core of building a Smart Home in mobile apps as well. It’s a real-time advanced technology that becomes more and more popular.

Internet of Things (IoT) creates a network and shares data between electronic devices and mobile apps. Thanks to IoT, people can control their electronic devices through mobile apps remotely from anywhere in the world. Just tap on the smartphone and you can regulate lights in your house, turn off the oven, close the garage, etc. 

In the coming year, we will see smartphones remotely controlling refrigerators, home security solutions, smart lights, and much more. 

Apps for Flip Phones 

Flip phones are now making an impressive comeback, even if the arrival of touchscreen phones with or without a button made these devices obsolete over a decade ago. 

From an application development perspective, applications can now be customized for flip phones as well. Since these phones are fairly new to the market, we will see a surge in apps compatible with these devices in 2021.

To bridge the gap between phones and tablets, the industry will move towards a new category –  foldable phones; mobile apps will also need to be optimized to instantly resize the screen between minimized and maximized versions. In any case, folding displays will be the new face of mobile devices, where developers will have a lot to consider, but this certainly has a bright future.

Event Streaming and Online Learning 

The way our social interactions work has really changed after the pandemic struck. The offline event industry may come to life by the next summer (if we are optimistic, of course) but it will never go back to its regular offline pre-COVID mode. The so-called “hybrid events era” will soon appear on the horizon. 

Tools like webinar platforms will enable large conferences to become bigger and smaller ones to grow worldwide as the internet breaks the need to take a plane and travel thousands of miles in order to attend a 1-day event.

Such platforms will grow and become more and more “non-typical” ones where you will have a possibility to listen to different speakers, go and visit virtual booths, where each company has their own virtual room with a chat, check their business profiles and where there is a room for tet-a-tet networking sessions. 

The same thing is about students who are focusing on improving their skills through online learning. Students, as well as their parents, consider such platforms time-saving, available and effective, where they can choose any course or teacher according to their preference. Even more, they are convinced that studying online is much better than enrolling in coaching institutes. 

Therefore, building online learning apps can be profitable as well as beneficial for both mobile app developers and students.

Augmented Reality 

Augmented Reality which is present in photography-related apps and mobile games submerges virtual objects in the real world as if they’re actually next to the user. AR allows people to experience digital content in practically the same way they experience the world in their everyday life. 

Mobile apps using this technology are quite famous among young users because it ensures an immersive adventure. If you open the Chrome browser on your mobile phone and type in the name of any animal in Google Search, then click on the “View in 3D” button – you can check out how Augmented Reality works!

Slowly but in any case, this technology is opening new doors of possibilities in mobile application development. Moreover, applications for this technology can go even further in such business fields as health, security, training, and many more.

Accelerated Mobile Pages (AMP) 

User-friendly and fast – these are the features that top app developers focus on and everyone wants to have in the apps they use. It is not a secret that today clients will just quickly leave the site that takes too much time to load, and the same happens with applications.

Hence, Accelerated Mobile Pages is the best solution for the above-mentioned problem. AMP websites can load even with the 2G network, and it can be a great solution when you want to read any article. Interaction with an AMP website is not possible, but if your purpose is for instance to read the article, then it can get loaded rapidly even with 2G or 3G.

AMP website is a lower version of an HTML page, so it can be loaded very quickly even in a weak network: it is light in design and it loads only basic elements. This technology will be a real hit in the upcoming future which not only enhances user engagement on your website but also improves your visibility for search engines, helping to get more traffic as a result. 

Artificial Intelligence & Machine Learning

Such an effective combination of artificial intelligence and machine learning creates a new level of apps development quality: AI-based filtering concepts i.e. FaceApp (remember, when we were all so interested in how we will look in 50 years?) have once drastically changed rules of AI usage and we never looked back.

In 2021, AI & ML solutions won’t end up with Chatbots and Voice Assistants only. A rise of AI-based cameras, Static Pictures Recognition, and their further Classification, particular Object Identification, etc.

If you are interested in Automated ML in Android or iOS app development, all previous data would be gathered and analyzed to define possible errors and eliminate them a second after! For instance, Apple’s Core ML helps with adding AI solutions to apps.

Beacon Technology

Beacon technology has made a statement and shown its potential so we are expecting to hear about it not once. In two words, if someone with a device gets into a beacon zone, the app catches signals and recognizes them, showing specific content/ads/product promos to its potential consumer. That is why such a targeted instrument will be highly demanded in the advertising and marketing sectors. It basically cuts down unnecessary sales funnel phases showing products to people which they actually want and buy afterward.

Beacon technology would become a great solution for attracting clients for such sectors as healthcare, Offline quests, HoReCa, tourism, education, entertainment. For example, by visiting an art gallery you would be able to experience an amazing virtual tour with interesting facts or explanations of every piece of art, taking it all to a whole new level of perception!

By using beacon technology businesses come closer to potential consumers showing only relevant notifications.

Mobile App Security Solutions

In 2020 users decided to download 205+ bn apps, according to Statista. But, they agreed to give products access to any possible personal info: Name and Surname, email details (and connected passwords), payment options info, telephone numbers, addresses, etc. It is not a secret that there are hundreds of cyber crimes happening every day.

After some major user data leakages from giant companies like Facebook (who have admitted their security issues officially), businesses are desperately searching for effective cybersecurity solutions to protect their clients.

In 2021, more development agencies are moving towards a security-first approach and preparing the world for the highly anticipated DevOps Strategy. By the way, over $124 billion will be invested globally in information protection.


Digitalization and increasing virtual presence together with the Covid-19 pandemic have enhanced the need to use a variety of mobile apps. New and updated solutions emerged in 2020 as a response to the worldwide lockdown. 

Moreover, everyone prefers convenience and quality over anything else these days, and what can be better than a supreme mobile app? And so it is a great moment to start developing your mobile app with the above-mentioned mobile app trends in mind.
