    One of NOGRAVITY's most innovative projects is a consumer-oriented data visualization platform. The client was a mobile network regulator in Europe that frequently tests and audits EU cellular service. While the client had technical resources to analyze the data in-house, it lacked expertise or experience in interactive platforms and went to NOGRAVITY for a solution. NOGRAVITY created a web application that automates location and quality of service visualization from the client's data, which enabled consumers to better understand their cell service. The client was highly satisfied with the quality of the work and NOGRAVITY's dedication.

    "NOGRAVITY helped us prioritize information and requirements. They organized each stage of the workflow and shared the most topical information with our client. The team was available 24/7. If we had to meet a deadline, they were willing to remain at the office after hours, and even work from home." – Project Lead, Telecommunications regulatory agency
