Case Study: Custom Mobile App Development for 99coaches
Challenge
99coaches is a Germany-based sports technology startup that set out to empower team coaches with a mobile platform that simplifies planning, organizing, and tracking training sessions across multiple sports and teams. Coaches frequently juggle administrative tasks, player management, and training design, yet struggled with paper-based plans and disjointed digital tools. To solve this, 99coaches envisioned a mobile-first solution that would centralize training workflows and performance tracking in one intuitive app.
To bring this vision to life, 99coaches partnered with IT Craft for full-cycle cross-platform app development, focusing on high performance, offline capabilities, and long-term scalability.
Coaches across sports face a range of logistical and operational challenges:
- Creating and distributing structured training plans
- Managing multiple teams and player rosters
- Monitoring performance metrics over time
- Planning effective drills and training sequences
99coaches recognized that coaches need technology that works both online and offline — especially in field environments where connectivity can be unreliable — and that performance tools should be accessible on a wide range of devices, including legacy smartphones.
Before development began, several key challenges had to be addressed:
- Build a unified mobile app that works seamlessly on both iOS and Android devices.
- Enable offline functionality with smart caching and data sync once connectivity is restored.
- Ensure responsive performance even on older or lower-end smartphones.
- Design an architecture optimized for ongoing growth, allowing the platform to expand beyond a single sport.
- Support a rich set of features for training planning, animated drills, and performance tracking under a modular structure.

Solution
IT Craft led the engineering effort from prototype to production, delivering a robust cross-platform solution tailored to the coaching workflow.
Services we provided:
- MVP Development
- Web App Development
- Mobile App Development
- DevOps
Engagement model:
- Dedicated software development team
Cross-Platform Mobile App Development
A unified codebase was developed to deliver consistent features across both Android and iOS devices. Cross-platform development accelerated delivery, reduced maintenance overhead, and ensured feature parity across platforms.
Offline-First Architecture
Smart caching strategies were introduced, allowing coaches to access drills and training plans offline. Data entered while offline automatically synchronized once an internet connection was available — critical for on-field usage.
Device Compatibility & Performance Optimization
The team replaced native WebView components with optimized alternatives (e.g., Crosswalk) to support SVG animations and interactive drills even on older Android devices. This ensured that coaches with a wide range of hardware could still benefit from the app’s full capabilities.
Scalable, Modular Architecture
The app’s structure was modularized to support future expansion into additional sports and training formats. Built-in analytics components enabled tracking of player and team performance over time.
Tech Stack We Used
JavaScript, Ionic, Meteor, MongoDB, AngularJS, jq.mobi, and Crosswalk WebView enabled cross-platform mobile development with offline support and a scalable architecture.

Results
Operational Impact
- Coaches gained a unified mobile app for planning sessions, managing players, and accessing animated drills.
- Offline functionality allowed uninterrupted usage in field environments without internet.
- Data synchronization ensured continuity between offline and online work modes.
User Experience & Adoption
- The app performed reliably across a wide range of devices, including older smartphones often used in amateur and youth sports.
- Thousands of basketball and football coaches adopted the app and provided positive feedback on usability and performance.
Technical Refresh & Scalability
- A reworked backend and optimized architecture prepared the platform for long-term evolution and feature expansion.
- Built-in analytics tools enabled performance tracking at team and player levels.
Market Success
- The platform has remained active in the market for over five years with a growing user base.
- Rapid iteration and deployment — especially without App Store review delays — shortened time to market for new features.
By partnering with IT Craft, 99coaches successfully transformed a validated prototype into a scalable cross-platform Sports & Coaching Tech solution. The app streamlined the entire coaching workflow — from training design to performance tracking — while addressing real-world constraints like offline access, device compatibility, and modular scalability.
This project illustrates how strategic engineering and smart architecture can elevate sports technology platforms, delivering lasting value to coaches and teams alike.
