I need a full-featured mobile app built from the ground up and, alongside it, a modern, minimal logo that will become the core of the brand identity. The app itself should be coded natively for both iOS and Android (or in a robust cross-platform framework such as Flutter or React Native if that brings better speed and maintainability). Expect standard features—secure user accounts, clean UI, solid backend integration—but I’m open to your recommendations on architecture and technology choices. For the visual side, the logo must feel fresh and uncluttered: flat shapes, restrained colour palette, instantly recognisable at small sizes. Deliver the master vector file plus app-ready icons in all required resolutions. The finished work will be accepted when the following are in place: • A fully functional, test-ready app installable on current iOS and Android devices • Source code with clear, well-commented structure and build instructions • Logo delivered in AI/SVG, PNG, and layered PSD (or equivalent) with transparent backgrounds • App icon set derived from the logo, exported to correct platform specifications • A brief hand-off document covering deployment steps, asset usage, and any future scaling notes Timelines are flexible but please outline a realistic milestone plan in your proposal.
