Quick answer

A cross-platform mobile app for both iOS and Android can be designed, built and submitted to both stores in 30 days for a fixed $2,500. One React Native codebase serves both platforms, which is why two apps cost roughly what one native app would.

The plan

Day one to day 30, written down.

You get this schedule before you commit, not after. If a phase slips, that is mine to absorb — the price and the date were agreed before anything started.

The scheduleDay 1 → day 30
01Scope lockDays 1–3
02DesignDays 4–12
03BuildDays 13–24
04Two-platform testingDays 25–28
05Submit to bothDays 29–30
  1. 1

    Days 1–3

    Scope lock

    One feature list, agreed for both platforms. Parity is the default; anything platform-specific gets decided now rather than discovered in week four.

  2. 2

    Days 4–12

    Design

    Screens designed once and checked against both platforms' conventions, so neither feels like a port of the other.

  3. 3

    Days 13–24

    Build

    One codebase, both targets. Test builds go to TestFlight and Play's internal track around day 21.

  4. 4

    Days 25–28

    Two-platform testing

    Real devices on both sides. This is where cross-platform work earns or loses its reputation, so it gets proper time.

  5. 5

    Days 29–30

    Submit to both

    Both listings finished and both builds submitted. Apple's review takes one to three days; Google's is usually faster.

Who books this

Built for

Founders who need to be everywhere their users are from day one

Businesses tired of quotes that double the moment Android is mentioned

Teams validating an idea who cannot afford to guess the platform wrong

Real situations

Five ways this shows up, and what actually fixes it.

Not hypothetical — the shape of the problem before someone books this sprint, and the specific part of the build that resolves it.

Situation 1

Quoted double the moment Android came up

A founder got a clean native-iOS quote, then watched the number roughly double the moment they mentioned needing Android too — two separate codebases, two separate bills.

One React Native codebase serves both stores, which is why two platforms cost roughly what one native app would.

Situation 2

Needs to be everywhere on day one, not phase two

A startup validating a consumer idea can't afford to guess which platform their early adopters are on, because guessing wrong means rebuilding the whole go-to-market plan.

Both iOS and Android ship from the same 30-day sprint, so there's no platform bet to get wrong at launch.

Situation 3

Two freelancers, two codebases, two different bugs

A team hired separate iOS and Android freelancers who built inconsistent features on different timelines, and now every product decision has to be implemented twice, sometimes differently.

One codebase means one place to change something — features ship identically on both stores from the same build.

Situation 4

Validating fast without picking the wrong platform first

A founder needs real user feedback within a month but doesn't yet know whether their audience skews iOS or Android, and picking wrong would waste the entire validation window.

Testing builds land on both TestFlight and Google Play's internal track around day 21, so feedback comes from both audiences at once.

Situation 5

Told cross-platform apps 'don't feel native'

A previous developer talked a founder out of React Native, claiming cross-platform apps always feel like web views bolted onto a phone.

React Native renders genuine native components — the same framework Shopify runs its flagship commerce apps on at over 99.9% crash-free sessions.

The honest part

When 30 days is the wrong answer.

A fixed deadline only works when the scope genuinely fits inside it. These are the cases where I will tell you so rather than take the booking.

Apps whose core is heavy graphics, AR or games — native is the right call and I will say so.

Products needing sustained background processing like continuous location or audio, where native gives control React Native cannot.

Scopes with a large custom backend attached, which is a separate project with its own number.

Scope$2,500 · 30 days

Inside the 30 days

  • One React Native codebase serving iOS and Android
  • Full product design, checked on both platforms

  • Products needing sustained background processing like continuous location or audio, where native gives control React Native cannot.
  • Scopes with a large custom backend attached, which is a separate project with its own number.

Real work, sized and priced separately. You hear it before you book, not at handover.

Questions

Before you book

Because React Native uses a single codebase for both platforms. The engineering is done once rather than twice. Design, testing and store submission still happen on both sides, which is why it is not half the price of two native apps but roughly the price of one.

App Store + Google Play submission inside a 30-day sprint

The timeline on this page covers design + build + submit. Store review is a separate queue you do not fully control. Plan the sprint so submission is early enough that review slip does not erase the month — without pretending the store will approve on a fixed calendar day.

What must be ready before you hit submit

Ready itemWhy it blocks submit
Final bundle / buildReviewers install what you upload
Privacy labels / data disclosuresIncomplete forms bounce the submission
Screenshots + store descriptionListing is part of the product
Account / entitlements accessSomeone on your side must own the App Store + Google Play account
Crash-free core pathReviewers exercise the primary job

Dual-store specific

  • Shared product scope — one job, not two apps with different brains
  • Staggered submit is OK; same acceptance checklist on both
  • Store assets in both sizes; do not ship one store with placeholder screenshots
  • Decision owner picks whether iOS or Android uploads first when review risk differs

Soft planning rule (aim to — not an SLA)

Planning rule (not an SLA): aim to upload by day 25 so store review has room to move. Day 30 means the sprint build and submit package are done — not a promise that Apple or Google has finished review or that the listing is live on the store that calendar day. If review takes longer, the build is still done; the listing goes live when the store finishes.

Scope that fits 30 days vs scope that blows it

Usually fits

  • One shared core experience
  • Single design system across both stores
  • Auth + primary job parity
  • Two listings, one product story

Usually blows it (wrong sprint — say so early)

  • Divergent feature sets per platform (Android gets X, iOS gets Y)
  • Native-only modules on both sides that double the craft load
  • Ignoring one store's review feedback because the other side already shipped

Cut list template (fill on kickoff)

  1. Primary user job (one sentence)
  2. Platforms in this sprint: iOS + Android (shared core)
  3. Explicitly out this month: ________________
  4. Decision owner (one name): ________________

If the wishlist needs three primary jobs, you need three sprints — or a different engagement. See also the hub expansion on /shipitlive for the full track map.

Design-engineering acceptance checklist (before submit)

Use this on day 28 — for us or any team you hire:

  • Empty, loading, and error states for the primary flow
  • Auth path (if any) recovers from wrong password / cancelled session
  • Type and spacing hold up on one current iPhone and two Android phones agreed at kickoff
  • Accessibility basics: dynamic type / content size where relevant; contrast on primary CTAs
  • Analytics or logging hook installed or deferred in writing
  • Store screenshot set matches the build you upload
  • Source / project access transferred to your account

Craft bar: If a screen only works with perfect demo data, it is not ready.

Extra questions

Who submits to App Store + Google Play?

You own the developer account. We prepare the build and listing assets; submission runs through your App Store + Google Play access unless you explicitly appoint otherwise in writing.

Native vs cross-platform for this page?

This page is the both stores sprint. If you only need one store this month, use /shipitlive/ios-app-in-30-days or /shipitlive/android-app-in-30-days — tighter focus, less review surface.

What if App Store + Google Play rejects the first binary?

We treat review feedback as part of launch: fix the cited issues, resubmit. Rejection reasons vary; calendar dates for approval stay outside anyone's honest guarantee.

How does this relate to AI agents (Grok Bot / Cursor)?

Agents can help with reversible chores (QA notes, changelog drafts). They do not own store craft or the publish account. For the longer seat map, see What Is Grok Bot? Complete Guide, Grok Bot vs Cursor Cloud Agent, and Who publishes — Framer, Cursor, Grok Bot.

30 days from now, this could be live.

A 30-minute call decides whether the scope fits. If it doesn't, I'll tell you what would.
