Fantabase - Mobile App Design & Development

Fantabase is a mobile app designed to help fantasy football players make faster, smarter decisions by centralizing news, roster data, and AI-driven insights in one place. The goal was simple: reduce noise, save time, and give users an edge without overwhelming them.

Improvs.com handled the product end to end, from UX and design to mobile development, backend architecture, and AI integration.

Fantasy football players rely on too many fragmented sources: social media, injury reports, articles, spreadsheets, and chat threads. This creates decision fatigue, missed updates, and slow reactions during critical moments.

The challenge was to:

Aggregate large, constantly updating datasets

Personalize content per user and roster

Deliver insights instantly, especially on mobile

Make AI feel helpful, not gimmicky

All while keeping performance fast and the UI calm.

We built Fantabase as a mobile-first product with personalization at its core.

Key features include:

Sleeper account sync to instantly import leagues and rosters

Player watchlists that drive a personalized news feed

A scrollable, curated feed filtered by what actually matters to the user

An AI assistant, Howie Wynn, that provides roster-specific advice, updates, and explanations in natural language

The product was designed to feel effortless: open the app, scroll once, know what to do.

Cross-platform mobile app with performance-optimized lists and animations

Backend designed for real-time updates and scalable data ingestion

AI workflows built around contextual awareness, not generic prompts

Caching, pagination, and indexing to support large datasets without UI lag

Every technical decision was driven by one rule: speed under pressure.

A product that handles live sports data without performance degradation

Clear improvements in user engagement through personalized feeds

AI interactions that feel actionable instead of speculative

A scalable foundation ready for additional sports and features

Fantabase successfully transformed fantasy football from scattered inputs into a single, focused experience.

Fantabase is a strong example of how thoughtful design, solid engineering, and practical AI can turn a complex problem into a simple daily habit.

It’s not about more data.

It’s about the right data, at the right moment.
