HoopSquad: A Native Basketball Community App Built on FlutterFlow in 12 Weeks
How Kreante designed and shipped a cross-platform mobile app for a basketball community startup — Figma to iOS/Android in 12 weeks using FlutterFlow and Firebase.
HoopSquad is a Washington DC-based startup building a community platform for basketball players and fans. Their goal: give players a dedicated space to organize games, rate each other, and connect — the way basketball culture actually works, not the way generic social apps handle sports.
They needed a native mobile app for iOS and Android, a web admin panel, and a launch-ready product in under 3 months. Kreante delivered from design to app store submission in 12 weeks.
The challenge
Generic social apps don’t handle the specific mechanics of recreational sports communities well. HoopSquad needed:
- Game creation and attendance management, with support for recurring games
- Player profiles with a structured rating system
- A social feed with posts, comments, likes, and media sharing
- User roles and onboarding flows (fans vs. players)
- Push notifications for game updates and community activity
- Google and Apple sign-in from day one
Building this natively with a traditional React Native or Swift/Kotlin stack would have taken 6+ months with a larger team. FlutterFlow allowed Kreante to move faster without sacrificing native performance on both platforms.
Timeline
Weeks 1-2 — Discovery and Figma design
Kreante started with a full discovery sprint to map user flows, data structure, and integration points. Two user types (Fan and Player) required distinct onboarding paths, profile structures, and permission levels.
The full UI was designed in Figma before any development started: feed views, game creation flows, player profiles, rating interfaces, and the admin panel. The database schema was mapped in Whimsical alongside design. HoopSquad validated both before build began.
Weeks 3-10 — FlutterFlow development
Core platform built on FlutterFlow with Firebase as the backend:
- Authentication: Sign-up and login with Google and Apple OAuth, plus email/password. Role assignment at onboarding (fan or player), including a quiz flow for player profiles.
- Social feed: Post creation with text and media, like and comment system, post sharing, and a pinned questions feature for community engagement.
- Game management: Create and schedule games, manage attendance, set recurring games (weekly pickup runs, league games), and cancel registrations. Game history per player.
- Player profiles: Ratings system, stats, quiz-based profile completion, edit profile flow.
- Push notifications: Firebase Cloud Messaging for game updates, new followers, and community activity.
- Email integration: Brevo connected for transactional emails — registration confirmations, game reminders, welcome sequences.
- Search: Find players and games across the platform.
- Admin panel: Web-based dashboard for platform management, content moderation, and user oversight.
Weeks 11-12 — QA and app store submissions
End-to-end QA across iOS and Android. Edge case testing on game recurrence, notification delivery, and rating calculations. Both apps submitted to the Apple App Store and Google Play Store.
Two months of post-launch support included for bug fixes.
Stack
| Layer | Tool | Role |
|---|---|---|
| Design | Figma | Full UI/UX + user flows |
| Mobile app | FlutterFlow | iOS + Android native app |
| Backend | Firebase | Database, auth, push notifications |
| Brevo | Transactional email flows | |
| Project management | Notion | Documentation, user stories |
| DB schema | Whimsical | Data model visualization |
Why FlutterFlow for this build
FlutterFlow compiles to native Flutter code, which means genuine iOS and Android performance — not a web view wrapped in a native shell. For a community app where feed performance, smooth animations, and push notification reliability matter, this was the right choice.
The productivity advantage: a Kreante team using FlutterFlow ships a cross-platform native app in roughly half the time of a traditional Flutter or React Native build, without giving up control over the underlying code. HoopSquad went from zero to app store submission in 12 weeks. A traditional build would have taken 6 months minimum.
Kreante applies the same approach to other mobile app builds — sports platforms, community tools, marketplace apps — where speed to market matters and native performance is non-negotiable.
