According to Statista, mobile retail commerce revenue via smartphones will generate 221.2 billion US dollars in the United States in 2021. The source projected smartphone retail commerce sales to surpass 400 billion US dollars by 2024, nearly double the forecast for 2021.

What else you need to remember is that the eCommerce industry is highly competitive. Hence, to retain your users in your app, it needs to follow the most effective UX tips for a shopping app, be innovative, and use cutting-edge technologies. But, of course, in chasing the retail trends, don't forget that the primary purposes of your app should be to meet your business purposes, your clients' needs, and follow existing ecommerce market trends.

Even if you already have an existing application, that doesn't mean your job is done. You'll often need to update the software so that it doesn't seem outdated to new users.

Hence, all the trends in m-commerce and technologies of the online shopping industry are the guidelines you should consider when starting to develop an ecommerce app in android.

Step-by-Step eCommerce Mobile App Development Process

Developing an eCommerce mobile app is a systematic process that requires planning, foresight, and technical know-how. Here's a step-by-step guide to help you navigate this terrain:

Discovery & UI/UX

Before diving into how to develop an ecommerce app, it's essential to do a thorough market analysis. Understand your target audience and their preferences, and closely examine what competitors are doing. This stage is about establishing a vision for the app and setting clear objectives. Once the foundation is laid, focus on the app's design. Create a primary interface sketch and ensure the design is intuitive and aligns with your brand. The user experience should be seamless, and the visual appeal should capture the essence of your brand.


After locking in the design, it's time to bring the app to life. Choose whether to opt for native (like iOS or Android) or cross-platform development. The development tools, languages, and frameworks should align with your app's objectives. Initially, focus on building an MVP (Minimum Viable Product), emphasizing core functionalities. As the development progresses, ensure that features like payment gateways and inventory management are seamlessly integrated.


Testing is an integral phase where the app's functionality and user experience are vetted across various devices and screen sizes. It's vital to identify and resolve glitches and continuously improve the app based on feedback, especially from beta testers who can provide invaluable insights.

Creating Technical Documentation & Launch

Prepare comprehensive technical documentation before the launch. This documentation should detail the app's workings, ensuring anyone who works on it in the future understands its architecture and functionality. Then, when the app is ready for the marketplace, optimize its presentation with engaging descriptions, compelling screenshots, and relevant keywords. And, of course, the app's launch should be accompanied by strategic marketing campaigns to garner attention and attract initial users.


After the launch, the journey doesn't end. Monitoring user behavior and engagement through analytics tools is crucial. Regular updates will ensure the app remains relevant and functional in line with OS advancements and mCommerce trends. Lastly, always encourage feedback from users. This continuous feedback loop will be a goldmine of insights, helping you refine and improve the app with time.

By following this systematic approach, businesses can ensure their mCommerce app not only meets the needs of their target audience but remains adaptable and resilient in a continuously evolving market.

Custom ECommerce App Design Best Practices

A good e-commerce app design can help you attract more new customers. Unsurprisingly, UI and UX are key parts of creating your solution because users will see the visual first. Therefore, you need to know what to look for when you do mobile app development for ecommerce business.

So, we'll tell you about the main design trends in this direction. Some of them may seem obvious. Still, it is vital to remember them when designing an app.


Designers often think that the more features a mobile app has, the more likely it's to succeed. But it doesn't work like this. Users want to interact with simple and logical elements in the application. People don't like wasting time trying to figure out how things work. Therefore, there is no need to complicate things that you can simplify.

Photo zoom

Imagine yourself in your client's shoes. You go to a mobile application and find the product you need. You are happy with the price and features but want to look closer at it. And here comes the time for zooming in photos. Thus, it is crucial to use high-quality images in the application.

Easy and fast login

With the advancement of technology, users are becoming more demanding. They want to login into mobile apps quickly and easily. Think about which method you could use: Face ID, Touch ID, or a 4-digit password.

The client should be thinking about buying goods in the app, not complicated authorization. By simplifying this process, you also help your business by ensuring a customer stays with you.

Challenges of an m-commerce app development

It would be best to consider that custom eCommerce mobile app development is complex. Therefore, you need to analyze what challenges your solution will face. And you will understand whether you will be ready for them in the future.

Ensuring seamless operation 24/7

Will your application handle a thousand users simultaneously? What about 10 or 100 thousand? Will it work correctly and without crashing every second? Before launching the mobile application, you will need to test it a lot, answering these questions. We advise you to be very responsible about this.

Avoid making mistakes in the application so as not to disappoint your existing and potential customers. Turn this challenge into your competitive advantage.

Guaranteeing data security

We understand that users will leave their data in the cabinet of your mobile e-commerce app. In addition, customers can still add information about their bank cards to purchase your products. Think through how to ensure the safety of all these important components. Don't forget about legislation regulating private data.

Making the app market-ready

You can create an eCommerce app that has good potential for successful results. But before you start developing, you need to understand which market you target. Do people have smartphones there, and how often do they use them for online shopping? You can try to enter a market with similar applications or where the right conditions have just formed. You can also try selling your products on eBay and other popular eCommerce platforms first. These solutions have analytics tools that'll help you determine how much of your products' demands comes from mobile app purchases, as well as other vital data. These insights enables you to gauge whether an app is necessary for your business. Get a clear picture of where you plan to launch your application – and tailor it to the market demands.

Optimizing development time

Building a live streaming shopping app can be time-consuming depending on budget, the number of features, and other components. Perhaps you would like to create an MVP first to evaluate its performance much earlier. You can even test this option on the market and see if it's worth spending resources on creating the full version at all.

eCommerce Mobile App Trends to Expect in 2023

At this point, we're going to talk about some of the top eCommerce mobile app trends that you can expect in the year 2022. These trends will help you understand how to develop ecommerce apps in android.

VR and AR Integration

A virtual showroom can allow you to "try on" any article of clothing or accessory, from glasses to sneakers. All you have to do is point the camera at the desired part of the body. Such an easy-to-use mechanism assures customers to look at products they might not have originally intended to buy. You can apply AR to clothing and furniture, interior design items, and cosmetics.

VR/AR integration in eCommerce mobile app

The integration of AR occurs through the selection and installation of a suitable SDK. Among the most popular are Google ARCore, ARToolKit, Vuforia, and Apple ARKit. It is worth noting that the VR app development cost quite often justifies itself.

Visual Search For Goods

The technology of visual search has developed by leaps and bounds in recent years as well. Images respond to the idea of a search more than keywords since they are queries in themselves. Search engines also interact better with visual components, which leads to more accurate results. Apart from visual search, it is also important to personalize the search results displayed to the eCommerce app users. This increases customer engagement and leads to higher traffic on the app.

Visual Search for Goods in eCommerce mobile app

Digital Wallets

Google Pay, Apple Pay, and PayPal are some of the digital wallets you should introduce for your eCommerce business. Besides making the payment process easy, you need to care about integrating the most common payment platforms for your targeted audience into your shop app. According to Statista, apps like Apple Pay or Google Pay in North America are believed to double between 2020 and 2025, although the Asian market size will be significantly larger.

Artificial Intelligence & Machine Learning Integration

Product recommendations can be improved to an unprecedented level due to the capabilities of ML. In the future, this technology will be able to offer products depending on your plans, desires, or even current weather patterns. Your e-commerce app development should take this into account.

Data analysis is another area where ML will be useful. The peak of machine learning potential lies in prediction, which goes far beyond human capabilities. It allows us to access an astounding range of information. Because of this database on which to draw, ML can make decisions leading to sales growth more accurately than a human ever could.
