MOBILE APP DEVELOPMENT PROPOSAL

Mobile App Development Proposal

A proposal from Northwind Studio outlining the design, build, and launch of a cross-platform mobile app for iOS and Android.

Project Overview

This proposal outlines the mobile app engagement Northwind Studio will run for Acme Co. It covers the design and prototyping work, the cross-platform build in React Native, the QA cycle, and app store submission support to get you launch-ready.

Objectives

• Ship a launch-ready app that users can download on day one.
• Deliver cross-platform parity so iOS and Android feel equally polished.
• Meet security and performance benchmarks before submission.
• Navigate app store review and approval on the first submission.

Scope of Work

The build runs across three phases. Each closes with a working deliverable and a review before the next begins.

What is included

• UI/UX design system and interactive prototype
• Cross-platform React Native build for iOS and Android
• Backend and third-party API integration
• Full QA testing cycle across target devices
• App store submission support through approval

Not included: backend infrastructure hosting, third-party API costs, ongoing maintenance post-launch, and marketing or app store optimization work. New scope can be added in writing at any time.
