I'm looking to develop an EMI Locker type app for both Android and iOS (FOR NEW + RUNNING DEVICES), along with an admin panel. The app should have the following main functionalities: - Save and manage EMI details - Send payment reminders - Track payment history - Lock Online Offline - Unlock - Track Location - Lock Others Apps (to select) - zero touch enrollment The ideal freelancer for this project should have prior experience in developing secure, user-friendly mobile applications, preferably with similar functionalities. Knowledge of creating an admin panel is a plus. This app will be used by Retail Mobile Shop owner, who sells Mobile Phone at EMI. and They will use this app to lock buyer phone when payments due. The user authentication for the app will be done through phone number and OTP. Therefore, experience with implementing secure and efficient authentication systems is essential. Please ping me if you're interested.

The idea is straightforward: give users one place to record and track every loan repayment securely. I’m still locking down the finer feature set, so the codebase must be modular enough for me to toggle or extend functions without a full rewrite. Native-level performance is essential; whether you prefer Swift + Kotlin, Flutter, or React Native is up to you, so long as the end result feels snappy and stable. Scope of work • Build and test two production-ready binaries that meet App Store and Google Play guidelines. • Set up basic analytics, crash reporting, and a clean project structure in a private Git repo. • Provide a concise hand-off document detailing libraries, build steps, and project architecture. Acceptance criteria 1. Smooth operation on iOS 14+ and Android 9+ to 15+devices. 2. No critical issues during a one-week beta test (testers supplied by me). 3. Successful first-round approval from both app stores. In your proposal, share the stack you’d choose, links to at least two similar apps you’ve shipped, and a milestone-based timeline covering design, MVP, polish, and submission phases.
