For my final-year project I need a fully functional mobile application that runs smoothly on both iOS and Android. The main purpose of the app is to help users keep track of their overall health in relation to the medicines they take. Core scope • Cross-platform build so a single codebase delivers native experiences on the App Store and Google Play. • Secure user sign-up/login and local data encryption. • Intuitive screens where users can log daily vitals, side-effects, and notes tied to specific medications. • Charts or simple analytics that turn those logs into easy-to-read trends. • Lightweight cloud sync so data is not lost when the device changes. I am happy for you to choose the framework you are most efficient with—Flutter, React Native, or any other tool that lets us meet Apple and Google review guidelines without compromise. Acceptance criteria • Builds install and run without crashes on recent iOS and Android versions. • All tracking entries save instantly and remain after the app is restarted or reinstalled from backup. • A brief report explains architecture, major libraries, and how to extend the app for future features such as medication reminders or a searchable drug database. Please let me know the estimated timeline for an MVP, along with any questions about the data structure or UI flow.
