One client. One week. One outcome.
We’re not splitting attention across six projects. Your week is yours. We move at the speed of decisions, not standups.
App in a Week
Your app idea, on the App Store, in five working days.
We build and submit your MVP for a fixed £2,995. No retainers. No 12-week roadmaps. One week of focused work, then you have something real to test against the world.
- Fixed price, fixed timeline
- App Store submission included
- Source code is yours
The problem
Most app ideas die in a Notion doc.
You’ve refined the pitch deck. You’ve drawn the user flows on the back of a napkin. Maybe you’ve even paid a designer for some screens. But the app itself? It’s still just a feeling. Meanwhile the founders who win are the ones with something users can actually open, tap, and complain about. The longer your idea stays theoretical, the longer you’re guessing.
- Agencies quote 12 weeks and £40k for the “discovery phase” alone.
- Hiring a freelance dev means three weeks of Slack pings and a Trello board with 78 cards.
- No-code looks tempting until you hit the first thing it can’t do.
The offer
Ship in a week. Learn in a month.
We take one client at a time. Five working days, Monday to Friday. By Friday evening your app is in App Store review. By the following week, you have real users tapping real screens.
Fixed price: £2,995
No hourly billing. No surprise change orders. No ‘discovery phase’ that quietly costs more than the build.
Cross-platform iOS, on the real App Store
Not a TestFlight prototype. Not a web wrapper. A signed, submitted iOS build under your developer account — built on Flutter or React Native so it can be cloned to Android later.
What you get
What’s included — and what’s not.
We’ve learned the hard way that vague scope kills weeks. So here’s the contract, written plainly.
Included in £2,995
- Up to 6 screens, built with Flutter or React Native (your choice — we’ll recommend on the kickoff call).
- One core user flow, working end-to-end.
- Sign-in via Firebase Auth (email + password, magic link, or Google).
- Basic design system: typography, colour, components.
- Light back-end on Firebase (Firestore, Cloud Functions, Storage) where the app needs one.
- App Store metadata: description, keywords, screenshots.
- Submission to App Store Review on Friday afternoon.
- All source code in a private GitHub repo, transferred to you.
- A one-page handover doc with how to run it locally.
Not included
- Custom illustrations, brand identity, or marketing assets.
- Android, web, or watchOS versions in week one (Android clone is a £495 add-on after iOS sign-off — see Pricing).
- Real-time chat, video calls, or live collaboration.
- Marketplace payments, escrow, or multi-party billing.
- Custom AI/ML models or proprietary algorithms.
- Ongoing maintenance after week one (we can talk about week two separately).
- Anything that requires an external compliance review (medical, financial, regulated data).
How it works
Six steps, five days, one app.
From the moment your deposit clears, the clock is honest. Here’s the rhythm of the week.
Pre-project pack
After the deposit, you get a short pack: a scope sheet, a design questionnaire, and a list of credentials we’ll need (Apple Developer account, App Store Connect, Firebase project, any third-party API keys). You return it before Monday.
Monday — kickoff & build skeleton
30-minute call to confirm scope and pick the framework (Flutter or React Native). We set up the repo, the project, the design tokens, the Firebase project, and the first screen. By 5pm Monday, the app boots.
Tuesday & Wednesday — core flow
We build the one user flow that defines the app. You get a TestFlight build at the end of each day. Feedback in plain English; no Jira, no tickets.
Thursday — polish & edge cases
Empty states, error handling, accessibility, loading skeletons. The app stops feeling like a demo and starts feeling like a product.
Friday morning — App Store assets
Screenshots, metadata, description, keywords, privacy policy. We finalise the icon and submit to App Store Review by 4pm.
Friday evening — handover
GitHub repo transferred. One-page handover doc emailed. A 15-minute Loom walking you through the codebase. The app is yours, in full.
Pricing
One price. One week. No invoices afterwards.

Not a fit? The qualifier will tell you in 3 minutes — and if so, we’ll point you somewhere better.
Add-ons
Android clone +£495
Once the iOS build is signed off and approved, we clone the codebase to Android with no changes or amends and submit to the Play Store. Same screens, same flow, same app.
Who this is for
This works for some people, and not others.
Honesty up front saves both of us a week.
A great fit if you…
- Have a clear, simple idea you can describe in one sentence.
- Want to test that idea with real users in the next two weeks.
- Are comfortable making product decisions in real time.
- Trust the constraint — five days, six screens — to focus the work.
- Have your own Apple Developer account (or are willing to set one up before Monday).
Not a fit if you…
- Need a polished, finished, scalable commercial product on day five.
- Want a marketplace, real-time chat, or anything regulated.
- Need design from scratch — brand identity, illustrations, custom motion.
- Want a long discovery phase before any code is written.
- Expect revenue from the App Store in the first month.
You’re not paying for the code. You’re paying to skip the eight months you’d otherwise spend deciding what to build, finding a developer, managing a developer, and arguing about scope.
About us
Ten years of shipping apps that people actually use.
App in a Week is a productised service from ROUGEdigital — a UK app studio that's been designing and building successful mobile apps for over a decade. We've shipped apps for early-stage founders, established brands, and venture-backed startups across iOS, Android and web. Some launched to thousands of users in their first week. Some quietly powered businesses behind the scenes. All of them shipped. App in a Week distils everything we've learned about what actually matters in week one of a new product: a sharp scope, a confident framework choice, and a build that gets in front of real users before the doubt sets in.

Honest answers to the questions you’re about to ask.
Why iOS first? What about Android?
Building two platforms simultaneously in five days means doing both badly. iOS first, validate, then port. Because we use Flutter or React Native, the same codebase clones to Android — once your iOS build is signed off and approved, an Android build is a £495 add-on with no changes or amends.
What if our app needs more than six screens?
Then it’s not a fit for App in a Week. The constraint is the product. If your MVP genuinely needs ten screens, the qualifier will catch that and we’ll part on good terms.
What if we don’t love what you build by Friday?
We have daily TestFlight builds and short feedback loops. There’s no big reveal — you see it taking shape every evening. By Wednesday it’s clear whether we’re aligned. If not, we course-correct then, not after.
Do we own the code?
Completely. We transfer the GitHub repo to your account on Friday. No licence fees, no per-seat charges, no permission needed to fork it.
What about ongoing maintenance?
Not included in the £2,995. After Friday, you’re free to hire whoever you want — the code is clean, well-documented, and uses standard Flutter or React Native conventions, so any cross-platform dev can pick it up. If you want us to keep going, we can talk about a separate week-by-week arrangement.
What stack do you use?
Flutter or React Native for the app — we recommend one based on your idea on the kickoff call. Firebase (Auth, Firestore, Cloud Functions, Storage) for the back-end. Boring, fast, well-supported, easy to hand over.
What about Sign in with Apple?
We use Firebase Auth by default — email/password, magic link, or Google. If your app must offer Sign in with Apple to pass App Store Review (e.g. you’re also offering a third-party social login), we’ll wire it up; otherwise we keep it simple.
What if our app gets rejected by App Store Review?
We handle the resubmission within 5 business days at no extra cost, as long as the rejection is for something we should have caught (like a bad reviewer note or a missing privacy string). If it’s rejected for content reasons specific to your idea, we’ll talk.
Do we need an Apple Developer account?
Yes. £79/year, paid by you, in your name. The app must live under your account so you actually own it. We’ll never publish under ours on your behalf.
Can you sign an NDA?
Yes, a mutual one. Send it before the qualifier and we’ll review.
What happens after the deposit?
You get the pre-project pack within 24 hours. We schedule a Monday kickoff call. You return the pack 48 hours before Monday. Everything is set up by the time we start the call.
Ready?
Three minutes now saves you three weeks later.
The qualifier is six short steps. It tells you in plain English whether this is a fit, and routes you straight to the deposit if it is.
