App UI Redesign PDF Mockups

My current app works but the interface is still at a first-draft stage. I need every screen redesigned, then exported to a single, clearly organised PDF that I can hand to developers. The core of the job is improving the navigation flow—menus, tab bars, back paths, anything that helps users move around without friction. While navigation is the priority, a friendlier layout and a warmer colour palette should support it so the whole experience feels welcoming and effortless. Here is what the finished package should include: • High-fidelity screen mock-ups for every view in the app, presented in PDF format. • A simple map or annotation inside that PDF explaining how screens link together. • Optional animation notes or short storyboard frames where motion could enhance understanding (loading transitions, button feedback, etc.). Figma, Sketch, Adobe XD, or similar UI tools are all fine—whichever lets you hit clean typography and pixel-perfect spacing. Please attach a detailed project proposal when you bid. Outline your approach, timeline, and any comparable work so I can see how you think through navigation challenges. Budget: INR 1500–12500
