Native mobile app development (Android & iOS)

We are looking for a high-level Mobile App Developer (or a small, dedicated team) to build the initial MVP of a modern Health & Lifestyle tracking application. The platform will focus on daily metric check-ins, custom activity goals, and smart workflow reminders. We are strictly focused on Native development: Swift/SwiftUI for iOS and Kotlin/Jetpack Compose for Android. We already have the core backend architecture and initial Figma wireframes mapped out. Now, we need a reliable developer who can take this from prototype to successful app store deployment. Scope of Work: User Ecosystem: Secure onboarding (OTP/Social login), clean user profile creation, and subscription management. Core Metrics: Interactive tracking dashboards, progress charts, and daily history logs. Smart Reminders: Custom local and push notification workflows based on user habits. Security & Sync: Secure API integration, biometric authentication (Face ID / Fingerprint), and reliable offline-first data caching. Store Deployment: Handling the complete publishing and review guidelines for both the Apple App Store and Google Play Store. Technical Requirements:Swift / SwiftUI (iOS) & Kotlin / Jetpack Compose (Android). Shared business logic or clean architecture approach is a plus (please specify your preferred core framework setup). Experience with REST APIs, secure local databases, and push notification networks (FCM/APNs). Strong eye for UI polish, fluid transitions, and modern micro-interactions. What to Include in Your Proposal: - Links to at least 2 native applications you have personally shipped to the stores, and a brief sentence on what your role was. - Your tech stack recommendation for connecting native mobile clients with a secure, scalable backend cloud database. In a few sentences: how would you optimize image/data uploading from the phone device to prevent app lagging or heavy battery drainage? Please include your rough timeline and budget estimate to deliver a polished MVP within a 2-month window. We are looking for a responsive, independent thinker who can communicate clearly and problem-solve independently. If this sounds like a fit, we’d love to hear from you!
