Full UI/UX Design for Flutter Sports Social App MVP | 8 Complete Deliverables, Milestone Escrow Payment, 7-10 Days Timeline, $1000-$1500 Budget
Budget: $1,000 – $1,500 USD
Project Overview
We are building a mobile MVP sports social application with core features: SMS login, LBS nearby users, 1-on-1 real-time IM via NetEase Yunxin SDK, user profile management, and outdoor GPS workout tracking. We are hiring a professional UI/UX designer to deliver full pre-development design assets for both Android & iOS Flutter builds. 8 sets of standardized design documents are required as full deliverables.
Mandatory Terms & Rules
Total fixed budget range: $1000 - $1500 USD, no hidden extra fees or post-bid price increases.
Delivery timeline: All 8 design packages must be fully finished within 7 to 10 calendar days.
Non-negotiable escrow payment rule: Full total funds will be deposited into Freelancer third-party escrow upfront. The total budget will be split equally into 8 separate parts. One portion of payment will only be released by the platform AFTER each single deliverable is fully submitted and passes our acceptance review. If any document fails review, you must revise it for free within 1 working day; we reserve the right to cancel the corresponding milestone and request a full refund if revisions remain unsatisfactory.
All design files must be created in Figma or MoDao, fully editable, with complete asset export and design spec support for Flutter development.
Full Mandatory Deliverables (All 8 items must be included, no exceptions)
Product Information Architecture Diagram: Clear display of app page hierarchy, navigation tabs, and all feature entry logic
Core Business Flow Chart: End-to-end flow of login, workout tracking, instant chat, friend request functions
Permission Logic Flow Chart: Full logic for guest/logged-in user access, location privacy authorization, and system permission control
Fully clickable low-fidelity prototype: Complete page jump interactions covering every core business scenario
Full Page Interaction State Specification: Document covering all button, input, popup, pull-down, loading interactive rules
Full Edge & Exception Adaptation Document: Rules for empty data, network failure, disabled GPS, permission denial, error pages
Minimalist UI Multi-Device Adaptation Design System: Unified color, typography, spacing & component library, compatible with all Android & iOS screen sizes
Development-ready asset cut package: Complete redline dimension marks, exportable assets directly usable by Flutter developers

Compatible with Chinese Android brands (Huawei, Xiaomi, OPPO, VIVO) and all mainstream iPhone screen sizes;
Clean layered Figma/MoDao files, complete design annotations, no missing layers or broken interaction logic;
