TAGonSoft

BACKGROUND

Introduce your business and what you do there.

I’m the CEO and founder of Mytello, a telecommunications company. We provide affordable, high-quality international calling services from any landline or mobile phone, connecting users to over 227 countries without basic fees or minimum turnover, via app or traditional phones.

OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire TAGonSoft to accomplish for your business?

We hired TAGonSoft to develop, maintain, and continuously improve our Mytello mobile app, which enables customers worldwide to make affordable international calls. Our main goal was to create a reliable, user-friendly, and high-performance application for both iOS and Android.

SOLUTION

What was the scope of their involvement?

TAGonSoft has been responsible for the development, maintenance, and continuous improvement of our mytello mobile applications for iOS and Android for many years. Their work covers the entire mobile app development lifecycle, from technical planning and UI/UX design to implementation, testing, deployment, and ongoing support. 

One of the most significant milestones was the complete redevelopment of our mobile applications using Flutter. By moving to a unified cross-platform framework, TAGonSoft helped us streamline development, significantly reduce maintenance efforts, accelerate the implementation of new features, and ensure a consistent user experience across iOS and Android. 

They also handle ongoing Flutter framework upgrades to keep our applications modern and compatible with the latest operating systems. 

Key deliverables include our complete Flutter-based iOS and Android applications, integration with our international calling infrastructure, VoIP and real-time communication functionality, implementation of new features, performance optimizations, and continuous improvements to the user experience. Over the years, we have gone through numerous updates, major improvements, and technical challenges together. 

TAGonSoft has consistently delivered outstanding results, combining excellent technical expertise with a deep understanding of our business needs. They don’t just develop what we ask for. They actively contribute ideas, suggest better solutions, and genuinely care about the success of our product. This makes them much more than a typical development agency to us. 

Over the years, TAGonSoft has developed and continuously improved many important features of our mytello app, including international calling via local dial-in numbers and internet-based VoIP calling, contact management, user registration and authentication, account management, and a seamless user experience across iOS and Android. 

They have also worked extensively on improving call quality, app performance, stability, and the overall user interface. Another important part of their work has been integrating the mobile applications with our backend systems and ensuring everything works reliably together. The team completely rebuilt the app using Flutter to streamline development, reduce maintenance efforts, and save time and resources. TAGonSoft handles the entire development lifecycle for iOS and Android, including UI/UX design, VoIP integration, real-time communication features, testing, feature implementation, and ongoing improvements.

After more than 10 years of working together, I can honestly say that they are much more than just a development agency. They are a true technology partner.Their technical expertise is exceptional, especially when it comes to complex mobile applications, Flutter development, and the specific challenges of telecommunications.

What really sets them apart is their proactive mindset. They don’t just follow instructions. They challenge ideas, suggest better solutions, and always think several steps ahead.
