Custom Mobile App Development Case Studies

Success Story - Managed Mobility Services Provider

About the Company

Marta_logoMARTA is one the top 10 transportation agencies in the U.S. It operates a network of bus routes linked to a rapid transit system consisting of 48 miles (77 km) of rail track with 38 train stations in the Atlanta, GA metro area.

The Challenge

Managing coding for different mobile platforms for their rider app was becoming a challenge. The app was lacking real-time location features. And they wanted to improve the user experience by minimizing the number of screens to simplify navigation.

The Solution

Charter Global collaborated with the MARTA IT team to redesign their new rider app. The new app was developed on a hybrid technology platform, Xamarin, so coding can be done once across mobile platforms. It’s also more scalable, adaptable, and resilient to provide better performance for high volume use.


The benefits of the new MARTA rider app include: Hybrid technology with one code base makes it easier to maintain, improved UI, Real-time bus and train availability, and live directions.

“We wanted to redesign our mobile app so it’s easier for our riders to use and easier for us to maintain. Charter Global had the people and skills to build it. We couldn’t have done it without them.”
