Product-led app studio · iPhone, Mac & web
Build what fits. Grow it with care.
We work out what's worth building, then design it, build it and keep it growing.
- Product judgment first
- Personal by design
- AI-forward, built to last
where we fit
Between a weekend build and a big agency.
Anyone can generate an app now, and we build with AI too. What AI doesn't give you is the hard part: knowing who it's for and what to build first, making it personal enough that people come back, building on a foundation that lasts, and staying after launch. We bring how big product teams work, at a size and price that fits.

Step 1 · Plan it Typically 1–2 weeks
Evaluate & Explore
$799 $399 of it credited to your build
Know whether it's worth building and what exactly to build, and see it working before anyone writes the real thing.
- The bets worth making, quick wins, and what to leave alone, in a private, interactive report
- Concept design and a working prototype, tested with real people
- A conversation to walk through it, and a fixed quote for the build
- Takes
- typically 1–2 weeks
- Good for
- a live app, a beta or an idea
- Paid
- up front
- Credit
- $399 toward your build
Step 2 · Build it Typically 3–5 weeks
Build & launch
from$1,999 a fixed price you agree up front
The real app, built from the tested concept and shipped to the App Store, or a focused revamp of one you have.
- Native iPhone, Mac or web, scoped after Evaluate & Explore
- Test builds on your phone as the work lands
- Launch handled, start to finish
- Takes
- typically 3–5 weeks, then Apple's review
- Scoped
- after Evaluate & Explore
- Paid
- as milestones land
- Included
- screenshots and a month of Care
Everything it includes
- A fixed price for a clear scope, paid as milestones land
- 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
- Small changes along the way are on us. A big new feature that wasn't in the concept gets its own price, and you choose when: before launch, right after it, or over time on the Care plan
- Want people to use your app from ChatGPT, Claude or Gemini? We can connect it. How that works
Step 3 · Keep it growing Every month, stop any time
Care plan
$349 a month, stop any time
Kept healthy, current and improving, month after month.
- Crashes, reviews and numbers watched
- iOS updates and fixes handled
- Improvements every month, chosen from real usage
- Billed
- monthly
- Stop
- any time
- Pace
- steady, every month
- First month
- included with every build
Everything it includes
- Crashes, reviews and analytics watched, and problems fixed as they come up
- iOS and platform updates handled, so the app keeps working on every new release
- 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
- Quiet months still count: what we learn from the data shapes what comes next
- A bigger change, like a new feature set, gets its own quote, or we fit it in over a few months of the plan
App Store media
Most people decide from the screenshots.
Your App Store page sells the app before anyone opens it. We design and write all of it, around the story your app tells best.
From $499 for a screenshot set, in about a week. A video and header art are quoted with it. Every build includes a set, and the Care plan keeps your page current.
Ask about App Store mediaWhat's on your App Store page
- Screenshots
- Up to ten. The first three show in search results, so they have to tell the story.
- A preview video
- Up to 30 seconds of the app in use. It plays silently in search, ahead of your screenshots.
- Header and search art
- Newer spots: a header across the top of your page, and an image or video for search results.
- The words
- Name, subtitle and promotional text, written to be found and to make the case in a line.

who's behind it
Hi, I'm Corey.
A product leader who designs and builds apps end to end. You work directly with the people building it, from the first sketch to the App Store.
- Product first. I work out what's worth building, and what to leave out, before anyone designs or codes it.
- Personal by design. I've spent years building personalization platforms, so the apps I build remember people and give them a reason to come back.
- AI-forward, not vibe-coded. I build with AI, on the engineering that makes an app hold up. Whether AI goes inside your app is a separate call: it has to earn its place.
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.)
-
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.
-
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.
-
Testing
Every change reaches your phone first through TestFlight. Nothing goes to your users until you've tried it.
-
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.
-
Wrap-up
When the work is done, you remove our access and get notes on everything that changed.
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.
In writing, before we start
- 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
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 a set of App Store screenshots and your first month of the Care plan.
How long does it take?
Typically 1–2 weeks for Evaluate & Explore, which ends with a prototype tested with real people. Then 3–5 weeks to build, plus Apple's review, which usually takes a day or two. 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.
What if I have new ideas once the build starts?
Good, keep them coming. Small changes and improvements along the way are on us. A big new feature that wasn't in the concept gets its own price, and you choose when it happens: before launch, right after it, or a little at a time on the Care plan. You'll see the trade-off before anything changes.
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.
I only have an idea. Can you handle everything?
Yes. Start with Evaluate & Explore: the Evaluation plus concept design and a prototype, 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, you 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.
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. 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 cover?
Keeping the app healthy and getting better every month: crashes, reviews and numbers watched, iOS updates handled, your App Store page kept current, and steady improvements chosen from real usage. Even a quiet month leaves you with what we learned and what to try next. A bigger change, like a new feature set, gets its own quote, or we fit it in over a few months of the plan.
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.
