We are looking for an experienced iOS developer to build a family-focused wellness application. The app will help users improve posture habits while managing screen time in a smart and engaging way. The application will be a single app designed for both parents and children, with different user roles and a smooth, user-friendly experience. It will involve background activity handling, real-time monitoring, and basic parent-child interaction within the app. We are currently in the transition phase from concept/POC to a production-ready application and are looking for someone who can take ownership of development and help bring this product to life. Please also answer the following questions when sending your proposal: 1. Have you worked with Apple's Family Controls or Screen Time API before? If yes, briefly describe what you built and any challenges you faced with entitlements or App Store approval. 2. How have you handled background processing in iOS, specifically keeping a monitoring process active while the user is using other apps? What limitations did you encounter and how did you work around them? 3. Describe a situation where an app you worked on was rejected by Apple during review. What was the reason and how did you resolve it? 4. This app involves restricting and unblocking access to other apps based on real-time conditions. What approach would you take to implement this reliably, and what edge cases would you anticipate?
