Now, let us dig deeper and find out what Machine Learning is and how to create a machine learning app. 

Types of Machine Learning algorithms for mobile apps

Machine Learning (ML) is a technology of automated data processing and decision-making algorithms. Such algorithms are designed to improve their operation according to the results of their work. Basically, it means “learning on the go.”

The more qualified data ML has, the more accurate the ML algorithm becomes. 

To build a model that uncovers connections Machine Learning uses the following three algorithms: 

  • Supervised learning when an algorithm learns from example data and associated target responses. This data might include numeric values or string labels such as classes or tags. Later, when posed with new examples, ML can predict the correct response. 
  • Unsupervised learning. ML learns from examples without any associated response. Thus, the algorithm determines the data patterns on its own.
  • Reinforcement Learning. ML is trained to make specific decisions from the environment. In this way, the machine captures the best possible knowledge to make accurate decisions.

As you can see from the chart below, ml apps are popular across different industries: 


Machine learning for finance predicts future trends, bubbles, and crashes. For example, ML can analyze information about borrowers to determine their credit rating. Machine learning is also handy in process automation. What can machine learning be used for in finance? ML replaces manual work, increases productivity, and automates repetitive tasks. 

As a result, applications machine learning in finance brings the following benefits: 

  • Reduction of operational costs due to process automation.
  • More income, which is a result of enhanced user experience and better productivity
  • Improved reinforced security and compliance.  


Another application area of machine learning is in medical diagnosis. In a healthcare system, machine learning combines the doctor's knowledge and makes the treatment more efficient and reliable. ML algorithm is used for diagnostic, personalized medicine, and other areas where time matters. The most notable healthcare machine learning usage cases are:  

  • Heart Disease Diagnosis
  • Cancer Detection and Prediction
  • Personalized Treatment

An example of machine learning applications in healthcare is our recent project. We developed and trained a Machine Learning Chabot for a patient support system. To find out more, read the case study. As well as this, we also took part in developing Nanopore DNA Sequencers, another machine learning project for healthcare with Machine Learning algorithm.

Media and entertainment

In this industry, Machine Learning helps media companies to provide more relevant video content to on-demand platform users. In most cases, media companies use this technology for: 

  • Building recommendation algorithms
  • Creating custom artworks
  • Analyzing customer behavior 

Besides, ML helps TV channels to detect fact-manipulated propaganda and fake news. An example is AI VERSUS, the ML algorithm that we have been involved in. The project required building a conversation user interface for Russian TV channel  Rain. AI VERSUS shows two different points of view of the political situation in the Russian Federation.

Customer Support & Self Service Providing quality customer service in e-commerce is another machine learning application in business. Doing so at scale is daunting. But, one answer is to use machine learning technology like chat-bots. Intelligent chatbots use natural language processing to communicate with a customer, identify an issue, and resolve it. Automating customer support makes it easier for you and your customers to have higher satisfaction. There's a lot of creativity to how machine learning can be used to help customers, chat-bots being just one example. But the intent remains the same: higher customer satisfaction.

Top Six Machine Learning Mobile Application Examples

Advanced algorithms transform the way users interact with their devices while bringing unique machine learning mobile app ideas. The list below includes the best apps that use machine learning. 

1. Snapchat. The application uses machine supervised learning algorithm for computer vision. Looksery, a Ukrainian startup, developed the algorithm behind the computer vision. Soon, the company was acquired with Snapchat for a whopping $150 million. Now, the mobile machine learning algorithm finds faces in photos to add fun elements like glasses, hats, dog ears, and more. For a more detailed explanation on how  ML Snapchat filters work, check out this article

2. Tinder uses an algorithm with reinforcement learning for the 'Smart Photos' feature, which increases the user's chances to find the perfect match. The app shows user photos to other users in random order. Then, Machine Learning analyzes how many right or left swipes each image receives. In this way, Tinder learns which photos are more attractive to other users. The algorithm reorders the user photos to put popular photos first.

3. Netflix. The app uses several reinforcement learning algorithms for personalized recommendations of movies and shows.  Besides this, Netflix uses machine learning for generating series and movie artworks. A computer vision algorithm analyses each movie screen to pick the best images and test them among the communities with a specific taste.

4. Yelp uses supervised Machine Learning to enhance user experience with “Recommended for You” collections. The ML algorithm skims the reviews for each restaurant listed. Then, ML determines the most popular dishes on how many times the meal was mentioned. Besides, Yelp uses ML to accumulate, classify, and label user-submitted photos with attributes. Such attributes include "ambiance is classy" or "good with kids" with 83% accuracy. 

5. Facebook applies a Supervised Machine Learning algorithm for detecting persons in images, news feed recommendations, friends suggestions, relevant ads and more. Also, Facebook uses ML to transform a panoramic photo into a 360-degree immersive experience. 

6. eBay applies a Reinforcement Machine Learning algorithm for the product recommender Chabot, called ShopBot. The Machine Learning algorithm helps ShopBot to understand what users are looking for. Chatbot then processes their text messages and images and finds the best match. eBay chat-bot has been praised for its excellent contextual understanding as well as its use of friendly language. 

As a result, ShopBot users are three times more likely to ask questions about specific products than those browsing eBay's inventory.
