How Machine Learning is Influencing Mobile App Development in 2021

The emergence of machine learning technology has made this application’s “wow factor” possible in a major part!

Have you ever wondered how Spotify chooses which music to play depending on your preferences, or how fitness and health apps can make workout recommendations that are exactly tuned to your current goals (even if you haven’t expressed them out loud)?

In this article, we’ll look at how Artificial Intelligence (AI) and Machine Learning (ML) are used in cutting-edge mobile app development, as well as their impact on the industry.

In today’s world, our mobile devices can identify spoken requests, assist us in keeping track of our hectic schedules, and even act as a translator.

As a result of the early success of this technology, an increasing number of organizations are investing in AI-based mobile applications.

According to one estimate, the global market for machine learning is predicted to expand by more than $20 billion by 2025, with a 44.06 percent annual growth rate since 2017.

The reason for this is that machine learning creates user-friendly systems with increased consistency and customer experience. 

Impact of AI and ML in Mobile Application Development

Machine learning is being used to generate customized apps that can understand user behavior and give a more personalized experience while also increasing user interaction. 


Machine learning aids in the classification of users based on data gleaned from their application and social media activities.

This information allows you to understand more about your clients’ interests, how they use your product and their preferences as consumers.

This data is obtained using machine learning algorithms and can be utilized to improve and shape your product’s content.

Applications Using Ml for Personalization

In this area, popular apps include UberEats, Uber, and Taco Bell. Uber and UberEats are ML-powered apps that display predicted arrival and delivery times on a map in real-time.

Taco Bell utilizes a machine learning bot to accept orders and provide recommendations based on customer preferences.

Data Mining

Data mining entails responsibilities such as data collection, storage, upkeep, and analysis. ML algorithms acquire a big dataset of clients and categorise the data to find trends.

Applications Using Ml for Data Mining

Travel apps are the finest example because they provide operators with business intelligence that allows them to optimise trips and timetables.

Improved User Engagement

Some machine learning features can entice customers to utilise your app on a regular basis. Users who are lost in a product can employ conversational and AI virtual assistants to help them comprehend it.

Applications Using Ml for User Engagement

Machine learning is used by Facebook and Amazon to manage smart requests and increase user engagement.

Users can utilise digital assistants to help them write long emails and make phone conversations. Prisma has a bot that can resize and add filters to your photos for you.

Mona conducts product searches on over a hundred different websites in order to assist you with your shopping.

Upgraded Security

Almost any sort of application can benefit from machine learning to improve security and authentication.

Face detection, fingerprint access, biometric information, and audio/video/voice recognition are some of the features that aid in the detection of fraudulent behavior and ensure secure access to personal information.

Applications Using Ml for Security

Applications like TurboID and BioID utilize eye recognition and face detection to let users safely and securely access websites and other apps.

Automated Reasoning

Mobile app developers can use ML to manage the execution of simple functions and tasks. Automated reasoning helps in collecting insights from historical data and using them to solve a problem.

Applications Using Ml for Task Automation

Google Maps, Uber, and similar navigation apps use these algorithms of automated reasoning to help users reach their destination as quickly as possible through obtaining travel data.

Evaluating Customer Behavior

To give customers a consistent, logical experience, companies examine user behavior by looking at data (age, gender, preference, requests, search items, app usage frequency, and so on).

To analyze user behavior and make appropriate app feature changes, NLP and machine learning algorithms can be integrated into app architecture.

Applications That Use Ml to Evaluate Customer Behavior

Netflix uses a recommendation structure to make movie/show suggestions for the users, and Youboox also uses the same engine to recommend books. 

Cutting-Edge ML Mobile Applications in 2021

Modern machine learning algorithms are bringing new cutting-edge mobile applications to the market, thus modifying the way in which users interact. The top applications in this list are as follows:


Tinder uses machine learning algorithms to find a specific match. The program examines data such as posts, photos, percentages of user likes, swipes on an image, and so on.

An algorithm, for example, prioritizes the most swiped photo for that particular user. The algorithm used increases the likelihood of users finding an ideal match.


Netflix has saved roughly around $1 billion via their recommendation system because 80% of their TV shows are suggested by this system. Explicit and implicit data is the basis behind these recommendations.

The ML algorithms of Netflix (linear regression, logistic regression, etc.) are trained by user reviews, ratings, user search requests, content lists and behavior. Algorithms get acquainted with this behavior over time and offer filtered content. 


Snapchat simulates computer vision using supervised machine learning techniques. Face tracking algorithms identify human faces and use them to create items (glasses, beauty filters, dog faces, objects, and so on) and change the texture of the image.

Google Maps

Google Maps uses geo-data acquired from user activities to train its machine learning models. Google Maps forecasts parking spaces using this data mining technique.

When the user’s location is turned on, the researchers get monitoring data and cluster it to train numerous models.


A person’s profile, hobbies, friends, and friends of friends are analyzed by Facebook’s machine learning algorithm.

Facebook recommends profiles in the “People You May Know” area based on your interests based on this judgment. 

Machine learning is used in Facebook’s Newsfeed, Facebook advertisements, and facial recognition, among other places.


Spotify’s machine learning model works in three stages.

The first is collaborative filtering, in which users are given recommendations based on personalised playlists of songs. This suggestion is based on a comparison of numerous user-created playlists.

The second one employs a natural language processing system to decipher lyrics, read blog posts, and engage in debates about popular singers and topics. This way, the algorithm categorizes its top terms and suggestions.

The audio model is used in the third step of the process when algorithms analyze data from audio tracks and provide recommendations based on similar music.

eBay Bot

eBay’s best feature, “ShopBot,” is made possible by machine learning algorithms. This bot recognizes what the user wants by understanding and processing the user’s text messages. Because of its user-friendly interaction and faultless grasp of context, eBay’s chatBot has become rather popular.

Other Applications of Machine Learning


Popular apps like Amazon, eBay, and AliExpress use ML methodologies to detect fraud, rank, understand and expand products in multiple categories, analyze forecasts and promotions, and learn user behavior.


Facial recognition is a useful tool for health and fitness smartphone apps that use machine learning algorithms to diagnose ailments and keep secure data for each patient.

Financial Assistants

VAs/chatbots have remarkable business applications, such as handling repetitive tasks and answering FAQs about products.

Closing Thoughts

For this generation, machine learning in mobile app development is a game-changer. Artificial intelligence and machine learning are driving the future of innovation and giving app users meaningful experiences.

According to a business’s scope and requirements, best-fit available machine learning models can be employed to fuel innovation and save money. You just need to have one!
