Start small. Grow as far as you like.

Every engagement covers one thing an app needs to grow, with a clear finish line and a price you know up front. Everything starts with Evaluate & Explore, for an app you have or one you're imagining. From there, build it and keep it growing, as far as you like.

  • A price before we start always
  • You own the code and the accounts always
  • Stop between steps any time

Step 1 · Plan it

Evaluate & Explore

Where every project starts. For a live app, a beta, or an idea: is it worth pursuing, what exactly should we build, and a prototype to prove it before anyone writes the real thing.

$799 one fixed price · typically 3–5 days · $399 of it credited to your build

  • The Evaluation: a clear call on the opportunity, the specific bets worth making, and quick wins, in a private, interactive report
  • The concept: concept design, design directions and working prototypes, put in front of real people
  • A conversation to walk through it, and a fixed quote for the build
  • $399 credit toward your build, if you go ahead

Just want the Evaluation? It's $249 on its own, and counts toward the full package if you add the concept later.

Step 2 · Build it

Build & launch

The real app, designed, built and shipped to the App Store, or a focused revamp of one you have. Scoped after Evaluate & Explore, so we both know what we're building and why, then agreed up front at a fixed price.

from $1,999 per build · typically 2–4 weeks · first month of the Care plan included

  • A fixed price for a clear scope, paid as milestones land
  • New builds on your phone as the work lands
  • Everything it takes to launch: App Store submission and review, developer accounts and certificates, privacy details, analytics, the backend, and launch week
  • Your App Store screenshots, designed and written to get people to download: the $499 set, included
  • Your first month of the Care plan: watched, tuned and improved right after launch

Step 3 · Keep it growing

Care plan

After launch, we keep your app healthy and keep making it better, every month. Billed monthly; stop any time.

$349 a month · first month included with every build

  • Crashes, reviews and analytics watched, and problems fixed as they come up
  • iOS and platform updates handled, so nothing breaks on the next release
  • New features and improvements every month, chosen from real usage and feedback
  • Your App Store screenshots and listing kept current as the app changes, with new versions tested against each other
  • No hours counted: if the data or your business says the app should change, even a bigger rework, it's included

Add-on · For an app that's already live

App Store screenshots

Your screenshots are the first thing people see on the App Store, and most decide from them whether to download. Already have an app? We'll design it a new set. Building with us? It's already part of Build & launch.

$499 on its own · typically under a week · included in every Build & launch, refreshed on the Care plan

  • A look at your listing and what people need to see first
  • A designed set of five to six frames, with headlines written to get people to download
  • Created as part of every Build & launch, and refreshed on the Care plan as the app changes, with new versions tested against each other

beyond the app

Your app, inside the AI tools people already use.

People now ask ChatGPT, Claude and Gemini to get things done. We can connect your app to them, so a customer, or your own team, can look something up or take action in your app without opening it.

  • Ask "what's due this week?" and get the answer from your app's real data
  • Act by asking for a change, and it happens in your app
  • Stay in control: you choose what an assistant can see and do, behind the same sign-in as the app

Built on MCP, the open standard these assistants use to connect to apps. Scoped in your Evaluation: part of a build, or added to an app you already have.

just have an idea?

Launch it with us.

No company, no developer account, no idea where to start? That's fine. We can launch your app under the Sprout Works roof and take care of everything around it: the Apple account, hosting, releases and the day-to-day.

It's still your idea and your app. Ownership, costs and how revenue is shared are agreed in writing before anything is built, and whenever you're ready, we'll move the app into your own accounts.

  • You bring the idea, and the people it's for
  • We handle design, build, the App Store, hosting and updates
  • Together we agree the terms up front, in plain language

your app, your accounts

You own everything.

Your code, your Apple developer account and your App Store listing stay yours. We work inside them as a guest, with access you can see and remove at any time. (Launching with us instead? The terms are written down from day one.)

  1. Code

    It lives in your GitHub, or we set up a repository in your name. You add us as a collaborator; every change arrives on a branch you can review.

  2. Apple

    You invite us to App Store Connect with a limited role, just for your app. That's enough to build, test and submit updates. No passwords are shared, and the app never leaves your account.

  3. Testing

    Every change reaches your phone first through TestFlight. Nothing goes to your users until you've tried it.

  4. Release

    We submit to Apple together (reviews usually take a day or two), and you decide when it goes live: all at once, or gradually over a week.

  5. Wrap-up

    When the work is done, you remove our access and get notes on everything that changed.

questions

Good things to ask.

How much does an app cost?

Builds start at $1,999, and each one is quoted as a fixed price for an agreed scope before it starts, usually after Evaluate & Explore, which credits $399 toward it. A focused revamp of an app you have sits near the start; a new app with accounts and a backend costs more. Either way, the price covers everything it takes to launch: App Store submission and review, developer accounts and certificates, privacy details, analytics, the backend and launch week. Every build also includes your first month of the Care plan, so the app keeps improving right after launch.

How long does it take?

Typically 3–5 days for Evaluate & Explore, then 2–4 weeks to build and launch, so most apps go from idea to the App Store in less than a month. Improving an app you already have is often faster. These are typical timelines, not promises: we confirm yours once we understand the scope, before any build starts.

Who owns the code and the app?

You do, completely. The code lives in your repository and the app in your Apple developer account. Once an invoice is paid, the work is yours.

What do you need from me for an Evaluation?

A link to the app (App Store or a TestFlight invite), a test login if it needs one, and time to talk about your goals. No code access is needed. For an idea, bring whatever you have: a sketch, a doc, apps you admire.

I only have an idea. Can you handle everything?

Yes. Start with Evaluate & Explore: the Evaluation plus concept design and prototypes, so you can see it working before anything is built. If you don't want to set up a company or an Apple developer account, we can launch it with us, with ownership and revenue terms agreed in writing first.

Can you take over an app from another developer?

Yes. Start with an Evaluation: it covers whether the code and the accounts can be recovered, what shape the code is in, and what it would take to move forward.

How do updates reach my users?

We build and upload, you try it on your phone through TestFlight, then we submit it to Apple. Once it's approved, you choose when it goes live.

Do you build Android apps?

Not today: iPhone, iPad, Mac and the web. If Android matters for what you're building, you'll hear that up front, along with how to think about it.

Can my app work with ChatGPT, Claude or Gemini?

Yes. We can build a connection (an MCP server) so those assistants can read from your app and take actions in it, for your customers or just your team. You decide what they can see and do, and it sits behind the same sign-in as the app. More on how it works.

How do you use AI?

Where it earns its place. It makes the work faster, which is part of why the prices are what they are, and nothing ships until we've tried it ourselves and it meets our bar. Inside your product, it's used only when it solves a real problem for your users.

What does the Care plan actually cover?

Whatever the app needs to keep getting better, without an hour count. If the data, your users or a real business need tells us something should change, we change it inside the plan, even when that means a bigger rework one month. We don't watch the clock on that. Brand-new directions or nice-to-haves with no evidence behind them are different: we'll talk them through and quote them separately if they make sense.

How do payments work?

Evaluate & Explore is paid up front. Builds are paid in parts as agreed milestones land, so you're never far ahead of the work. The Care plan is billed monthly and you can stop any time. And yes, an NDA is fine.
