Impact of AI on User Experience and Mobile Development: Innovation or Saturation?

In this insightful episode, Vincent Pillet, innovation expert and co-founder of User Agents, discusses significant changes in mobile development and user experience on the 135grammes podcast.

Artificial Intelligence: A Revolution in Mobile Development

Since 2007, mobile devices have dominated digital consumption, a trend largely propelled by the launch of the iPhone and the widespread popularity of App Stores, according to Vincent Pillet, co-founder of User Agents. He believes that the evolution of mobile usage can be encapsulated in one term: artificial intelligence.

Mobile Applications: Between Saturation and Innovation

The mobile app market has exploded in recent years, but many apps lack real utility, leading to what Vincent calls a “saturation of uselessness”, where apps are frequently downloaded and then deleted due to their lack of added value.

For over 15 years, they have been shaping our everyday lives:

– 136 billion apps downloaded in 2024
– 258,000 downloads per minute
– $150 billion generated from in-app purchases (+12.5% in one year)
– 6 apps used monthly, 7 daily
– 3.5 hours spent daily on apps

Despite this saturation, innovation continues to drive the market. New interaction models, conversational interfaces, and immersive experiences are becoming more prominent, and App Stores are getting choosier, prioritizing apps that provide real value.

AI: A New Dawn for Mobile Interfaces

At the forefront of innovations is the “rise of AI in apps,” as Vincent states. Intelligent assistants like Apple Intelligence and Google’s Gemini are revolutionizing mobile interactions. Far from replacing traditional apps, they enhance and personalize the user experience.

Mobile Development: Towards a Smarter and More Ethical Future

AI is profoundly transforming mobile development, fostering interest in more contextual and personalized approaches. Vincent believes the future challenge is to “find a balance between innovation, respect for users, and relevance of services.” Developers and agencies like User Agents play a crucial role in avoiding cognitive overload and promoting a more responsible approach to data collection and use.

The future of mobile lies in creating smarter, tailored experiences with a focus on ethical, useful AI. Such an approach is vital for gaining user trust and ensuring the sustainable adoption of future innovations. Market players must also strive for transparency and relevance to avoid the pitfalls of digital overstimulation and misinformation.
