I need an iOS application that connects to my smart ring, collects the raw sensor values over Bluetooth LE, and then stores every data point on my home server inside a Docker container. The app must handle multiple user profiles, so each family member can sign in and see only their own records. Core tracking features – Activity monitoring (steps, calories, distance) – Sleep analysis with stages and nightly summaries – Continuous heart-rate logging – Menstruation and stress trend dashboards – Push-up reminders that can be scheduled for specific dates or times Authentication The primary sign-in method should be a classic “create your own account” flow. If adding Gmail login can be done without much overhead I’ll gladly enable it, but the standalone account system is the must-have. Back-end expectations All data has to land in a Dockerised service on my home server. Please design the API so future charts or exports are easy to add, and make sure the database structure supports more than one user out of the box. Deliverables 1. Swift-based iOS app ready for TestFlight 2. Bluetooth connection module for the ring (documentation will be provided) 3. REST or GraphQL API running in Docker, plus a docker-compose file 4. Basic web admin panel or CLI script for user management and backups 5. Short hand-off guide so I can extend the project myself Acceptance criteria • App syncs activity, sleep and heart data in real time (maximum 30-second delay). • Users can register, log in, log out and reset passwords securely. • Scheduled push-up notifications trigger at the exact time set, even after phone reboot. • Data for each user is isolated inside the Docker database and visible only after authentication. • Code compiles and runs on the latest iOS version and a current Swift toolchain. If you already have experience with SwiftUI, CoreBluetooth, JWT-based auth, and Docker networking, you’ll fly through this build. Looking forward to working together.
