How We Ship a Production Mobile App in 6 Weeks

Most agencies quote 4-6 months for a mobile MVP. We ship them in 6 weeks. Same scope, same App Store and Play Store submission, same Stripe / RevenueCat billing. The difference is not magic — it is ruthless scope discipline and parallel work. This is the schedule we run.

What kind of mobile app fits a 6-week timeline?

The 6-week timeline works for apps with these traits:

• A single primary user role (no admin app in the same release).
• 1-2 core workflows the user repeats.
• Auth + onboarding + 6-10 screens.
• One backend, ideally one we have already shipped (Django or Node).
• Standard integrations only — Stripe / RevenueCat, OneSignal, Sentry, Cloudinary or S3.

If your "MVP" is a marketplace with two-sided onboarding, a chat module, a payments flow, an admin dashboard and a referral system, it is not a 6-week project. It is a 14-week project pretending to be smaller.

What is the week-by-week schedule?

What gets cut?

We cut more than we keep, and we are transparent about it on the kickoff call. Here is what is always cut from a 6-week mobile MVP:

• Admin app — we ship a web admin (we use Django Admin or a thin Next.js dashboard) for week 2 onwards. No native admin.
• Chat — if chat is core, the project is 10 weeks. We use a third-party (Stream, Sendbird) only.
• Localisation — English only on launch. Localisation is a 2-week task we do post-launch.
• Offline mode — read-only offline is fine. Offline write is post-launch.
• Custom design system — we ship on top of shadcn-react-native or NativeBase patterns; bespoke design system is post-launch.
• Deep referral / virality features — share-a-link only.

What stack do we ship on?

Our 6-week default is React Native (Expo) + a Django or Node backend. Reasons:

• One codebase, two stores — saves 35-45% of engineering time vs native.
• Expo's EAS Build and EAS Submit cut a week of build infra setup.
• OTA updates via Expo Updates let us hot-fix bugs without store review.
• Our team has shipped 14+ Expo apps; we know where the sharp edges are.

We pick Flutter only when the product needs heavy animations or pixel-perfect identical rendering across platforms. For 80% of B2B and B2C mobile MVPs, React Native is the right call in 2026.

How do we keep the founder unblocked?

The schedule collapses if the founder cannot make decisions inside 24 hours. We enforce three rules:

1. Daily decision window — 15 minutes at the same time every day. All open questions land here.
2. Default answer — every question has a default we will ship if the founder does not respond in 48 hours. The default is in the spec.
3. Written change requests — anything that adds scope is a written request with a 24-hour re-estimate. No silent slippage.

Founders who follow these three rules ship on time. Founders who treat the daily window as optional usually slip by 1.5x.

What is the cost?

A 6-week production mobile MVP runs USD 38,000-62,000 all-in at our 2026 rates. That covers two senior engineers, one designer, a project lead's time, and the App Store / Play Store submission. See our full SaaS MVP cost breakdown for context.

How do we keep code quality high under a 6-week sprint?

Compressing 16 weeks of typical agency work into 6 weeks does not mean dropping quality — it means picking the right quality bars. Ours, in priority order:

1. TypeScript strict mode on the mobile codebase — non-negotiable; saves more time than it costs in week 4.
2. End-to-end tests for the 1-2 core workflows only — Detox or Maestro. We do not chase 80% e2e coverage at MVP; we chase 100% coverage of the workflow the user actually pays for.
3. Unit tests for business logic, not UI — Jest for backend models and state reducers; nothing for visual components.
4. Manual QA day every Friday — a dedicated QA engineer walks the app on a physical iPhone and a physical Android, never just the simulator.
5. Crashlytics or Sentry wired from week 1 — not at submission. Real-device crash reports during build catch bugs the simulator never hits.

Skipping any one of these is what causes the "6-week MVP that needs 4 weeks of stabilisation post-launch" pattern. We do not ship that pattern.

What happens after week 6?

Most founders go onto a capped monthly retainer for weeks 7-16. We use that window to ship the cut-from-MVP features (admin app, localisation, offline mode) in priority order. Roughly half our mobile clients keep us past week 24; the other half move to an in-house engineer once the product has product-market fit.

What does the post-launch hotfix sprint look like?

Week 6 always includes 3-4 days of reserved capacity for hotfixes triggered by review feedback, real users on TestFlight, and edge-case crashes that staging never surfaces. We treat this as part of the 6-week build, not as a separate phase, because shipping past review without it is how teams end up doing 2.0 releases that should have been 1.0.1.

How do we handle App Store and Play Store review?

Apple review averages 1-3 days in 2026 when the build is clean; Play Store internal-track review averages a few hours. The build is clean when we ship with:

• A proper privacy manifest and tracking declarations.
• Working sign-in with at least one third-party provider plus email (Apple requires this if you offer any third-party login).
• A demo account for the reviewers, pre-populated with realistic data.
• Screenshots and ASO copy localised to en-US, en-GB and en-AU at minimum.
• A working delete-account flow inside the app (Apple required).

Missing any one of these triggers a rejection that adds 3-5 days. We bake the checklist into the week 4 deliverable, not week 6.
