What impact can a mobile app have on your business?

In our previous article, Mobile Apps in 2025: Why Get Started?, we showed that apps are no longer an option but a strategic necessity for modern businesses. They shape how customers interact with a brand and determine a business's competitiveness in an increasingly mobile-first environment.

But beyond this obvious fact, one question remains essential: what is the concrete impact of a mobile app on a business, whether it's a startup, an SME, or a large company?

This is what we will explore in detail in this article, analyzing the effects on visibility, customer relations, revenue, loyalty, and digital transformation.

The rise of mobile-first

Mobile usage exceeds desktop

For several years now, smartphones and tablets have surpassed computers in terms of browsing and online shopping. By 2025, more than 70% of global web traffic will come from mobile devices, and this proportion continues to grow.

This means that a company that does not invest in a mobile app risks being invisible where its customers actually are. A responsive website is a first step, but an app takes it further by offering a smooth, fast, and personalized user experience.

The role of search engines and natural referencing

Google already favors mobile-first indexing, which means that websites and content adapted for smartphones are better referenced. But an app adds another dimension: it can be optimized for App Store Optimization (ASO), giving visibility in stores (App Store and Google Play) in addition to traditional search engine results. In 2023 alone, mobile accounted for 50% of internet traffic. This represents a dramatic increase since 2010.

Mobile apps as conversion accelerators

From visitor to prospect

A mobile app is not just a technical tool, it is a powerful commercial lever. It allows you to convert a simple visitor into a prospect more quickly thanks to simplified forms, targeted notifications, and shorter user journeys than on the traditional web.

Even an optimized website often requires several steps to fill a shopping cart or sign up for a newsletter. With an app, sometimes all it takes is a visible CTA or a quick login button (via Google, Facebook, Apple) to convert in just a few clicks.

Impact on the conversion funnel

A well-designed app significantly reduces friction in the conversion funnel. It includes:

• short, user-friendly forms,
• one-click payments with Apple Pay or Google Pay,
• personalized recommendations based on browsing history.

The result: conversion rates up to three times higher than those of a traditional website.

Improved customer relations and loyalty

A personalized experience

Thanks to the data collected via an app, companies can offer a highly personalized experience. Whether it's push notifications, targeted offers, or tailored content, each user receives a customized journey.

This personalization promotes loyalty. Rather than having to win back customers through costly digital marketing (SEA, social media, emailing), the app allows you to maintain a direct and constant link with the user.

An enriched and connected CRM

A mobile app can be linked to a CRM or marketing automation solution, enabling advanced customer relationship management: segmentation, lifecycle tracking, automatic follow-ups, behavior analysis.

In a B2B context, it even becomes a sales tool for managing prospects and opportunities directly from a smartphone.

Financial impacts: ROI and growth

Reduced marketing costs

Investing in a mobile app may seem expensive at first, but it optimizes marketing expenses in the long term.

A good example is retargeting via push notifications. Instead of continuously paying for Google Ads or social media ads, the app allows you to re-engage an existing customer at no additional cost.

Increase in average basket size and repeat sales

In e-commerce, an app encourages repeat purchases. Users who have downloaded an app place more orders and spend more because they benefit from an optimized interface and simplified purchasing processes.

Studies show that app users spend an average of 30% more than users who only visit a website.

Integration of new technologies

Artificial intelligence

By 2025, apps will be heavily integrating AI to analyze behavior, anticipate needs, and offer relevant recommendations. This will transform apps into true digital assistants capable of guiding users and boosting conversions.

Augmented reality and 5G

AR and 5G enable unprecedented experiences: 3D product visualization, virtual try-ons, and immersive demonstrations. These innovations increase engagement and differentiate a brand from its competitors.

Conclusion

In summary, a mobile app has a profound impact on a company's growth: better visibility, more conversions, increased loyalty, optimized marketing costs, and integration of new technologies.

In 2025, not having a mobile app will mean leaving the field open to competitors.
