I have a live mobile app on both iOS and Android that needs a full refresh. My priorities span three areas at once: • Sharpen the User Interface so the screens feel modern, consistent and intuitive. • Optimise Performance—faster load times, smoother animations, lower memory use. • Add a short list of new features that I will share once you have reviewed the current build. I’ll give you access to the existing repositories and an overview of the current architecture. After an initial code and design audit, I’ll need a clear action plan with milestones, then iterative builds I can test on TestFlight and internal Android tracks. Deliverables 1. Updated source code with in-line comments and a brief change log. 2. New UI assets integrated and pixel-perfect across common screen sizes. 3. Performance metrics (before vs. after) demonstrating tangible gains. 4. Newly implemented features fully functional and covered by basic unit or widget tests. 5. Release-ready builds for both App Store and Google Play. Show me examples of cross-platform apps you’ve improved in these exact areas and outline which frameworks or performance tools you prefer to work with. Let’s make this app feel brand-new.
