Mobile commerce sales in the US are expected to double between 2020 and 2025. As an online seller, you may be wondering whether you need an app for your business to stay current and meet this growing trend.

To promote your business online to mobile shoppers, you need to understand the different tools that are available and which one will best suit your business. Do you really need an app, or is a great mobile experience enough? Before answering this question, it's important to first understand the differences between an app vs website. While they can share similarities, they have different strengths and weaknesses.

In this article, we discuss the debate between an app vs website and how to determine which solution is the better primary investment for your business.

What is the Difference Between an App vs Website?

A mobile website is a mobile-optimized version of a company’s website that can be accessed via a mobile device’s browser. An app, on the other hand, is a standalone software application that is downloaded and installed on a mobile device.

What is an App Exactly?

An app—short for “software application”—is a program that is downloaded on a mobile device from an app marketplace to work on an operating system like iOS or Android. Some companies build apps to encourage customers to interact with their brand and products in a self-contained experience on their mobile devices.   

Progressive Web Apps: In recent years, "progressive web applications” (PWAs) have emerged as a useful alternative to traditional apps. PWAs are essentially websites built to display in an app-like way, sometimes with features like full-screen display and push notifications, when accessed by a device with a certain screen size.

Benefit of an App vs Website

The biggest advantage of an app that it is an owned marketing channel. Your app lives on your customer’s mobile device, allowing you to communicate directly with them through push notifications and to curate information based to their interests, location, and usage behavior. This enables you to send tailored offers and recommendations to customers that keep them shopping within your app. 

Today’s shoppers want to see unique and personalized online experiences. Users that download your app are your best customers, and you’re able to provide the best possible experience to these high-intent shoppers with a direct marketing channel that you own and control. Apps can offer faster access to your content and provide smoother interactions with your brand, making it easier to move shoppers down the conversion funnel.

There are other benefits of having an app vs website, including: 

Device accessibility

Since most shoppers have mobile devices on them, an app allows your business to reach your customers in potentially more personal ways. The ability to connect with both customers and new users that are aware of your brand opens up additional touchpoints for your business and allows you to build relationships with them.

In addition, some apps can be used offline. While functions like checking out and making calls only work online, basic app information like store hours and products can be accessible without service. This provides additional accessibility for shoppers.

Mobile device features 

Because an app is designed specifically for mobile devices, your business will be able to take advantage of unique mobile device features like:

  • Fingerprint scan
  • Camera
  • Gyroscope
  • Tactile gestures
  • Push notifications

For example, you can set up geolocation to allow shoppers to locate a nearby retail location or integrate with a mobile camera to enable shoppers to upload pictures to the app. These  features are important to consider when deciding between an app vs website.

Challenges with Apps

While apps provide a convenient experience, creating a mobile app is not just a one-time endeavor. To make your app successful (and profitable), your business needs to invest in developing, publishing, maintaining, and marketing your app. While you would also need to do the same with a mobile website, an app can sometimes require more development and marketing to create a solid experience and to ensure your customers use it.

For a big name business with a big marketing budget, getting your customers to use your app may be easier to accomplish. However, for many sellers, getting casual users to find your app and to commit to shopping on it may be more challenging. Your app needs to offer some unique and valuable functionality for users to want to adopt it.

With marketing channels like social ads, PPC, and SEO, you are dependent upon other companies and providers to surface your ads. This makes your business vulnerable to being “cancelled”, to algorithm changes, and to rising advertising costs. If you go the app route, you are more likely to navigate these challenges since an app requires considerable marketing effort. 

Finally, an app isn’t directly accessed on the internet—it must be downloaded and installed on a mobile device. An app requires you to provide regular upgrades and fix compatibility issues for every type of operating system. App publication and updates often require submitting the app to an app store for approval. With each update, you’ll have to inform users to update their app. 

What is a Website?

A website is your online storefront—it shapes your customer’s impression of your ecommerce business, guides them along the purchase journey, and serves as the focal point for how shoppers find and interact with you and your products. As more and more shoppers use their mobile devices to shop online, you need to make sure your website is enabled for mobile and delivers a mobile-first shopping experience.

What Is a Mobile Website?

A mobile website is when your website is fully optimized for mobile devices. This means that all your site content—from your navigation and checkout process to product pages and banners—is responsive and can be viewed effectively on smaller screens. Shoppers can experience the bells and whistles of your website right on their mobile device of of an apparel brand's mobile-optimized website

Benefits of a Mobile-Ready Site

A website may be sophisticated and functional on a desktop, but it may not offer the same experience across different mobile device brands, sizes, and types. Having a mobile-optimized site ensures that customers can still experience the best features of your website without compromise, creating a consistent brand experience. Other benefits on the side of a mobile-optimized site in the app vs website debate include:

Indexability (SEO)

Unlike an app that’s downloaded from a store, a website is indexed by search engines. This makes it easier for visitors to search for and find your website, giving you broader reach and visibility. 

Connected to the internet

A mobile-optimized website is connected to the internet and can be accessed online. It does not need to be downloaded like an app. Because it’s accessed online, a website can be easily shared between users and published on other platforms and channels unlike an app. 

Cross-device compatibility

A mobile website is designed to be compatible with any device. Unlike mobile apps which only function on specific platforms (like iOS or Android), a responsive website can be accessed from any mobile device regardless of the operating system, which means users can drop off on one device and be able to continue the same experience on another device.  

Responsive design

A website offers the benefit of responsive design, which means it will automatically scale to any screen size and provide an easy and robust viewing experience.  


Mobile-optimized websites can be easier to maintain than apps. Any updates made to your site will display across all device types, whereas an app will require separate changes and development for each operating system.  

App vs Website: Should I Build a Mobile-Optimized Site or an App First?

While both apps and mobile websites can be useful for an ecommerce business, it’s important to start first with a mobile responsive website. Your website serves as your brand’s flagship, and for many shoppers, it’s also the first touchpoint with your business. Having a strong mobile-optimized site is key to creating positive first impressions, attracting shoppers, and retaining customers.

As an ecommerce business, your mobile commerce goals are likely to deliver compelling content, establish your online presence, and provide a spectacular online experience that's easily shareable and searchable. A mobile-optimized site is the most logical choice to achieve these goals.

An app can also accomplish the same goals of promoting your business and engaging customers—however, its main benefits are providing a targeted standalone experience that takes advantage of mobile features. While an app can enhance your overall brand experience, you should invest first in a solid ecommerce website (with a strong mobile-optimized experience built into it) because this will serve as the primary driver for your business. Once your website is dialed in, an app can be the next step for your business.
