About app

App fit for a leader

With more than 24 million customers in the region, A1 needed a straightforward, bespoke customer-care platform that could save time and money while improving customer experience, all while being tailored to their complex demands.

We achieved that by creating a Common Base Technology platform, which allowed us to “develop once, deploy many” — using the same codebase, we created a standard set of features that could be customized for individual markets. That meant having 7 apps as a finished product, but without the need to build them from the ground up every time.

A1 Mobile App Development

We focused on giving our client an app that’s easily maintainable, improved upon customer feedback and upgraded, while also answering to real needs of our client’s customers.

This meant providing full control over accounts and subscriptions, tariffs & pricing info, billing overview for both prepaid and postpaid customers, a shop finder, and data-driven personalized offers.
