What an MVP app is for
An MVP (minimum viable product) tests one question: will people use and pay for this? It ships the core task of your app and leaves the rest for later. You learn from real users on the App Store instead of from a slide deck.
A good MVP is small, but it is not a demo. It runs on real devices, passes Apple’s review and keeps working when the next iOS version comes out.
How much MVP app development costs
In the US market, a native iPhone MVP built by a studio usually costs $50,000 to $100,000. Clutch reports an average of $90,780 for the app projects in its cost survey. Studios such as Lickability publish smaller projects at $50,000 to $100,000.
This range is a market reference, not a quote. Carvalho Karsten prices your app after the project review. The review lists the development stages, the integrations and the changes your idea needs, with a price for each.
Three things move the price the most:
| Factor | Lower cost | Higher cost |
|---|---|---|
| Accounts and data | No sign-in, data stays on the device | Sign-in, a server, data synced across devices |
| Integrations | None, or one well-documented service | Payments, maps, health data, a legacy system |
| Platforms | iPhone only | iPhone, iPad and Mac |
The app development cost guide breaks down each item.
App development for startups: what to cut
The fastest MVP does one job well. Write the one sentence your first user would say about the app, and build only what makes that sentence true.
These features usually wait for version 2:
- Social login with several providers, when email sign-in is enough to start.
- An admin dashboard, when a spreadsheet or a simple backend tool can do the job for the first 100 users.
- Android, if your early users are mostly on iPhone.
- Custom animations and themes.
Some items cannot be cut. Apple requires a privacy policy, and apps that let users create an account must let them delete it inside the app.
Why build the MVP in native Swift
Swift and SwiftUI are Apple’s own tools for iPhone and Mac apps. A native MVP uses new iOS features as soon as Apple releases them, with no plugin to wait for. The same code base also grows into iPad and Mac versions.
Cross-platform frameworks such as React Native and Flutter make sense when you need Android on the first day. The comparison in native vs cross-platform shows when each choice fits.
How Carvalho Karsten builds your MVP
- Project review. You describe the idea. The team maps the screens, integrations and risks.
- Proposal. You receive the scope, the price and the schedule in writing.
- Development with TestFlight. You install each new build on your iPhone through TestFlight, Apple’s app for test versions. You can invite your first users to test it too.
- App Store submission. The team prepares the store listing and handles Apple’s review until approval.
- Maintenance. After launch, the team fixes bugs and updates the app for each new iOS version.
The how Carvalho Karsten works page explains each step in depth.
How to tell your MVP is ready to launch
Your MVP is ready when a new user can finish the core task without help. Test it with 5 to 10 people through TestFlight before you submit. Watch where they stop, and fix only those points.
Three signs you are adding too much: the launch date keeps moving, new features arrive before anyone has used the old ones, and nobody can explain the app in one sentence. When that happens, cut back to the core task and ship.
What you receive at the end
- The app live on the App Store, on your own Apple Developer account.
- The full Swift source code.
- Access to App Store Connect and TestFlight, with a walkthrough of each screen.
- A written list of what version 2 could include, based on what your first users do.
