How We Take an App from Napkin Sketch to App Store in 10 Weeks
A behind-the-scenes look at our app development process idea to launch — discovery, design, build, and App Store submission, step by step.
Most founders come to us with an idea — sometimes a detailed brief, sometimes a voice memo, sometimes a literal napkin sketch. Ten weeks later, that idea is live on the App Store. This post pulls back the curtain on our app development process from idea to launch: what happens in each phase, why it happens in that order, and what we need from you at every step.
If you’re weighing whether to build, or trying to understand what working with a studio actually looks like before you sign anything, this is the page to read. You can also browse our work to see finished apps across multiple categories.
Why Ten Weeks?
Ten weeks is our target timeline for a well-scoped standard iOS app — one with a clear core use case, 4–8 key screens, a backend, and no major third-party integrations outside our control. It is not a magic number. Simple MVPs can move faster (8 weeks). Complex apps with AI pipelines, real-time features, or hardware integrations take longer — typically 7–12 months.
The ten-week frame exists because it is long enough to do discovery and design properly, and short enough to keep scope honest. Scope creep and timeline slippage usually start when there is no defined end point. A fixed target forces everyone — including us — to prioritise ruthlessly.
Phase 1: Discovery (Weeks 1–2)
Before a single screen is designed, we spend two weeks answering one question: what does this app actually need to do?
This is not a formality. Discovery is where we earn our fee. We run structured working sessions with you to:
- Map the core user journey from first open to the key action you want users to take
- Identify which features are genuinely essential on day one versus which can ship in a later version
- Surface technical risks early — API dependencies, platform limitations, anything that could blow up timeline or cost mid-build
- Agree on success metrics: what does a good launch look like for your business?
The output is a written discovery document — a single source of truth that defines scope, priorities, and acceptance criteria for every feature. This document becomes the contract that prevents “I thought that was included” conversations four weeks into development.
What we need from you in this phase: Your time. Two or three focused sessions (video or in-person), access to any existing research or data, and a clear picture of your business goals. You do not need to know how to build the app — that is our job.
Phase 2: Design (Weeks 2–5)
Design runs in two tracks: UX and visual.
UX (wireframes and user flow): We start with low-fidelity wireframes — grey-box screens that show layout and flow without any visual polish. These are fast to produce and cheap to change. We review them together, cut anything that adds friction, and lock the flow before investing time in visual design.
Visual design: Once the flow is agreed, we apply your brand — or help you build one if you don’t have a visual identity yet. Every screen is designed at pixel level for the devices it will run on. We include dark mode, accessibility considerations, and empty/loading/error states that most studios skip until QA catches them.
By the end of week five, you have a complete interactive prototype. You can tap through every screen as if it were a real app. This is the version you show to early customers, investors, or your team before a single line of production code is written.
What we need from you: Feedback on wireframes within 48 hours of delivery. The faster the feedback loop, the faster we move. Brand assets — logos, fonts, colour palette — are needed by the start of week three.
Phase 3: Development (Weeks 4–9)
Development starts in week four, overlapping with the tail end of design. We build in two-week sprints, each with a defined set of features and a working build you can test on your own device.
We build iOS-first in Swift, with clean architecture that supports future cross-platform expansion if you want it. Backend services run on modern, scalable infrastructure — the same stack we use in our own products like Launchcast and Clove AI.
Each sprint ends with a review call. You see what was built, test it yourself, and give feedback before we move forward. There are no surprises in week ten — you have been watching the app take shape the entire time.
What gets built in each sprint
| Sprint | Weeks | Typical focus |
|---|---|---|
| Sprint 1 | 4–5 | App shell, navigation, authentication, core data models |
| Sprint 2 | 5–7 | Primary feature screens, backend integrations, local storage |
| Sprint 3 | 7–9 | Secondary features, notifications, subscriptions, polish pass |
What we need from you: Decisions, promptly. When a design question comes up during development, we need an answer within 24 hours. Delayed decisions push the schedule. The builds we send you for testing — actually test them. Your feedback in this phase is what shapes the final product.
Phase 4: QA and App Store Submission (Weeks 9–10)
The final two weeks are dedicated to quality assurance and getting the app through Apple’s review process.
QA covers:
- Every user flow, including unhappy paths (network failures, empty states, unexpected input)
- Performance testing on older supported devices
- Accessibility audit against Apple’s Human Interface Guidelines
- Final design polish — a pixel-level review against approved screens
Apple review typically takes 24–72 hours for a standard app. We prepare the full submission — screenshots, App Store description, metadata, privacy labels, age rating — so you do not need to navigate that process alone. If Apple rejects the build (it happens, usually for a fixable reason), we handle the response and resubmission.
By the end of week ten, the app is live and indexed on the App Store.
What Does This Cost?
For a standard iOS app on this timeline, budget $15,000–45,000. Simple MVPs with fewer features start lower ($5,000–15,000). Apps with AI features, real-time data, or complex third-party integrations move into a higher range ($45,000–120,000+).
We work on fixed-price contracts for scoped projects, with clear change-request terms for additions. You know exactly what you’re spending before we start — no billing surprises.
| App type | Cost range | Timeline |
|---|---|---|
| Simple MVP | $5,000–15,000 | 2–4 months |
| Standard app | $15,000–45,000 | 4–7 months |
| Complex (AI / real-time) | $45,000–120,000+ | 7–12 months+ |
What Happens After Launch
Getting to the App Store is the beginning, not the end. The first 30 days post-launch are the most valuable learning period you will have. We recommend:
- Watch crash reports and analytics daily for the first two weeks
- Talk to your earliest users — five conversations will surface patterns no dashboard can show you
- Plan version 1.1 with the features that actually came up in user feedback, not the ones you assumed would matter
Most of our clients move into a monthly retainer for ongoing updates and new feature development after launch. We can also hand off cleanly to an in-house team if you have one — full documentation included.
Common Questions
Can you actually ship a real app in ten weeks, or is this a cut-down version? It is a real app — just a focused one. The ten-week sprint is designed for MVPs with a deliberately narrow feature set. We define that scope together in Discovery. If your idea genuinely requires more at launch, we will tell you and give you a revised timeline rather than overpromise.
What do I need to provide to get started? Mainly your time and your understanding of the problem you’re solving. You do not need wireframes, technical documents, or a development background. We handle everything from the product brief through to App Store submission.
Who owns the code and designs when we’re done? You do. Full IP transfer is standard in all our client contracts. Once the project is paid, everything — source code, Figma files, assets — belongs to you.
