Mobile App Developer Needed to Build Social Group Expense Tracking App (iOS + Android) - Contract to Hire
I am looking for an experienced mobile app developer (or team) to build Splitr, a sleek and modern social-first group expense tracker. The app is designed for travelers, roommates, and friend groups who need a simple and intuitive way to log expenses, split costs, and track balances together in real time.
The ideal candidate will be able to take Figma designs (or collaborate to create them), develop the full app from front-end to back-end, and deliver a polished, high-performance MVP ready for the App Store and Google Play.
Core Features Needed
• User authentication (email/phone/social login)
• Create groups & add members
• Add, edit, and delete expenses
• Custom split options (equal, percentage, custom amounts)
• Real-time updating across all group members
• Group feed/activity log
• Smart calculations of who owes who
• Push notifications
• Clean, modern UI with smooth animations
• Admin settings & permissions
• Secure backend, preferably Firebase or Supabase
Bonus Features (optional now, future roadmap)
• Multi-currency support
• Travel mode
• Receipt scanning
• Bill reminders
• In-app messaging
• Payment integration (Stripe / Apple Pay / Google Pay)
What I’m Looking For
• Someone reliable, experienced, and detail-oriented
• Strong communication & weekly progress updates
• Ability to own the project end-to-end
• Long-term partnership potential
Please include:
• Examples of similar apps you’ve built
• Your recommended tech stack
• Estimated timeline
• Your budget estimate for an MVP
Included below are some references to design and features we have explored in regards to the app, these are not set in concrete as experts I’m always open to ideas, features and more compelling user experiences and interface designs.
If possible I would love to start marketing building a website for wait list or a walkthrough video of how the app could work and other content pieces to start marketing and building brand awareness.
