Mobile App Development Proposal Template

Q: Should I include App Store submission in a mobile app proposal?

Yes, always. App Store submission is part of &quot;done&quot; — a working app that isn't in the store isn't shipped. Include first submission in your scope. Be clear that Apple review timelines are outside your control. Offer to handle developer account setup if the client doesn't have one (+$500 or included).

What goes in a mobile app development proposal

Mobile app proposals are the highest-risk of any development project type. The gap between what a client imagines ("an app like Uber") and what they can budget is almost always significant. Your proposal is where you establish what's actually in scope — and where you protect yourself from the "why isn't this feature included?" conversation six months in.

Define the MVP boundary before writing a single line of code

The most valuable thing your proposal does is draw the MVP line. An app idea has infinite features; a fundable build has ten. Your discovery process should surface:

What is the single core action the user needs to be able to take?
What features are required for that core action to work end-to-end?
What features feel important but can be Phase 2?

Build a feature list. Mark each feature "MVP" or "Phase 2." Present this in the proposal. Clients who haven't done this exercise with a developer before will often discover that their "MVP" was actually a full product roadmap — reframing it explicitly in your proposal saves both parties from a painful reckoning at invoice time.

Platform decision: iOS, Android, or cross-platform

State your recommendation and the reasoning. React Native and Flutter deliver ~80% of native quality at 50–70% of the development cost, and are the right choice for most MVPs. Pure native (Swift/Kotlin) is the right choice when the app needs hardware-level performance or platform-specific APIs that cross-platform frameworks don't expose well. Don't let the client drive this decision without giving them the full tradeoff picture.

Scoping backend and API work

Most apps need a backend: authentication, database, push notifications, and often a content management layer. Many development proposals quote the app without quoting the backend and then have a painful conversation when the client discovers the app needs an API server. Include in your proposal:

Whether you're building the backend as part of this scope
Which backend platform (Firebase, Supabase, custom Node/Rails/etc.)
What third-party APIs are needed and whether integration is in scope

App Store submission and maintenance

First submission to Apple/Google takes longer than subsequent ones — Apple review is 1–3 days on average but can take weeks for new accounts or complex features. Build App Store submission into your timeline and scope it explicitly. Ongoing maintenance post-launch is typically a monthly retainer: bug fixes, OS compatibility updates, security patches. Budget $500–$1,500/mo for a mid-complexity app.

Pricing ranges for mobile development

Simple MVP (5–8 screens, existing backend or Firebase, one platform): $12,000–$25,000. Medium complexity (10–15 screens, custom backend, iOS + Android): $30,000–$70,000. Complex apps (real-time features, hardware integration, AI functionality): $80,000+. These are contractor rates, not agency rates. Timelines: 8–12 weeks for simple MVPs; 16–24 weeks for medium complexity.

iOS App MVP for Northwind Apps

Hi Sam,

Here's my proposal for the Northwind Apps iOS MVP.

MVP scope (what's in): User auth (email + Apple Sign In), onboarding flow (4 screens), core feature: task list with priority + due date, push notification reminders, settings screen, App Store submission.

Phase 2 (not in this scope): Team collaboration, calendar sync, rich text editor, analytics dashboard.

Stack: Swift/SwiftUI (iOS 16+), Supabase backend (auth + database), Firebase for push notifications.

Timeline: Week 1–2: architecture + auth. Week 3–5: core features. Week 6–7: onboarding + notifications. Week 8–9: QA + TestFlight beta. Week 10: App Store submission.

First Apple review can take 3–7 days. I'll submit during Week 10 and account for that in the delivery date.

Frequently asked questions

How long does it take to build an app MVP?

A simple iOS MVP (5–8 screens, Firebase backend): 8–12 weeks. A cross-platform MVP (iOS + Android) with a custom backend: 12–18 weeks. These timelines assume one developer working full-time. Part-time development roughly doubles the calendar time, not the cost. App Store review adds 1–7 days.

React Native vs native Swift/Kotlin — which should I recommend?

React Native or Flutter for 90% of MVPs — faster to build, one codebase for iOS + Android, easier to maintain with a smaller team. Go native when the app has heavy hardware dependencies (ARKit, CoreML, Bluetooth), needs sub-60fps animation performance, or when the client has a dedicated iOS/Android team to maintain it long-term.

Should I include App Store submission in a mobile app proposal?

Yes, always. App Store submission is part of "done" — a working app that isn't in the store isn't shipped. Include first submission in your scope. Be clear that Apple review timelines are outside your control. Offer to handle developer account setup if the client doesn't have one (+$500 or included).
