A health-tech startup focused on daily wellness tracking and telemedicine for urban users needed a mobile app that worked seamlessly on both iOS and Android. With a limited budget and aggressive deadlines, the company approached Code Elevator to build and launch their MVP before an investor demo in just 6 weeks.
They required a modern, intuitive mobile app capable of:
Health logging (meals, mood, sleep)
Video consultations
Push reminders
Integration with Apple Health and Google Fit
Available in both iOS and Android app stores
- Building two native apps (iOS and Android) wasn’t feasible within their deadline
- They lacked an in-house mobile development team
- Needed a consistent user experience across platforms
- Data needed to sync securely in real time
They needed a cost-effective, scalable solution that wouldn’t sacrifice design or user experience.
Code Elevator proposed using Flutter, Google’s open-source UI toolkit, to create a cross-platform app with native performance and a shared codebase.
Team Composition:
- 2 Flutter Developers
- 1 Backend Developer (Node.js + Firebase)
- 1 UI/UX Designer
- 1 Project Manager
Execution
- Phase 1: Discovery & UI/UX (1 Week)
Designed wireframes and prototypes in Figma
Created a health-focused UI with calming colors and intuitive navigation
Mapped out core modules (logging, telehealth, reminders, analytics) - Phase 2: App Development (3 Weeks)
Built frontend using Flutter (Dart) with custom components for each module
Integrated Firebase for real-time sync, push notifications, and user auth
Set up secure video consultation using Jitsi Meet SDK
Added Apple Health & Google Fit integration using native plugins - Phase 3: Testing & Store Launch (2 Weeks)
Performed QA on 10+ devices and emulators
Passed Google Play and App Store requirements
Delivered app for investor demo—and helped them go live post-pitch
Code Elevator delivered an investor-ready MVP in record time. Flutter was the right choice, and the team handled everything from UX to backend. We couldn’t have launched without them.
