About the project with 99coaches
IT Craft worked with 99coaches to provide full-cycle cross-platform app development — delivering a mobile-first solution that helps coaches plan, organize, and monitor training sessions across teams and sports disciplines.
The 99coaches team came with a validated prototype and growing user interest. Their idea was to reduce administrative tasks for coaches by digitizing the entire training workflow — from designing drills to tracking athlete performance. They needed a partner to take their MVP to production level and ensure it worked smoothly on both iOS and Android devices, including older models.
Our developers rebuilt and optimized the system: redesigning the backend, improving responsiveness, and enabling offline usage. We ensured users could access animated drills, structure full training sessions, and sync data automatically when back online — whether coaching indoors or out in the field.
One of the main goals was to ensure smooth performance across device types, enable real-time and offline functionality, and provide a flexible cross-platform architecture that could easily scale to additional sports and training formats.

99coaches approached IT Craft with the need to turn a validated prototype into a scalable cross-platform app. Our role was to ensure stability, offline functionality, and performance across modern and legacy devices — while optimizing for future growth.
We contributed throughout the entire app transformation process, covering system migration, architecture redesign, and feature expansion. More specifically, our scope included:
- Full migration from Modulus infrastructure with zero downtime
- Implementing offline-first logic with prioritized caching of exercises
- Replacing native WebView with Crosswalk to support SVG animations on older Android devices
- Enabling instant access to 300+ animated drills and a modular drill planner
- Adding built-in analytics to track player and team performance
- Structuring the app to support multiple teams and sports with modular architecture
