Mi Movistar iOS: From Zero to a Powerful Self-Management App

Before 2020, Telefónica Venezuela did not have an iOS app. They required a fully native iOS solution to allow users to self-manage their accounts, perform transactions, and enhance their mobile experience while ensuring seamless integration with their existing APIs.

As founder and lead developer of Aerious, my company took on the challenge of developing and deploying the first-ever iOS version of Mi Movistar. Over the years, we have provided continuous frontend development, API integration, and App Store support, adapting the app to visual and functional upgrades led by Movistar’s internal design team.

From 2020 to January 2025, we have been a dedicated technical provider for Movistar Venezuela, ensuring their mobile app evolves alongside technological advancements and user expectations. As the largest telecommunications company in Venezuela, Movistar’s app is a critical tool for millions of users who rely on it for daily account management and transactions.
