Three ways to hire an iOS developer

You can hire a freelancer, add an iOS developer to your staff or contract a studio. Each one fits a different project. The table compares them on what matters for a small or mid-size company.

A freelancer is the cheapest way to fix one screen. An in-house developer makes sense once mobile is the center of your business. A studio sits in between: a team for the length of the project, with no hiring.

What you get when you hire Carvalho Karsten

Carvalho Karsten builds native apps for iPhone and Mac in Swift and SwiftUI. It does not split attention across Android, web and every other platform.

  • A dedicated Swift team. Gustavo Henrique Karsten, the CTO, has more than 20 years in software and leads the architecture and code of each app.
  • US East Coast hours. The team works from Santa Catarina, Brazil (BRT, UTC−3). Brazil has no daylight saving time. From November to March, Brazil is 2 hours ahead of Boston. From March to November, it is 1 hour ahead.
  • A US point of contact. Thiago Do Carmo, the CEO, has lived on Cape Cod for 21 years. The commercial address is 207 Iyannough Rd, Hyannis, MA 02601.
  • English, Portuguese and Spanish. Calls, documents and App Store listings in the language of your market.
  • App Store from start to finish. The team prepares your store listing, submits the app and answers Apple’s review until approval.

Overlap in practice. A 10 a.m. call in Boston is noon or 11 a.m. in Brazil. Your whole workday overlaps with the team’s, so questions get answers the same day.

How an engagement works

  1. Project review. You send the idea or the current code. The team maps screens, integrations and risks.
  2. Proposal. You receive the scope, the price in USD and the schedule in writing.
  3. Development with TestFlight. You install each new build on your iPhone through TestFlight and comment on it directly.
  4. App Store submission. The team submits the app on your Apple Developer account and handles the review.
  5. Maintenance. After launch, the team fixes bugs and updates the app for each new iOS version.

If the scope changes during development, you receive a new estimate before any extra work starts. The how Carvalho Karsten works page explains each step.

What to prepare before you hire

You do not need a full specification to start. A one-page description is enough for the project review: who uses the app, the one task it must do well and any system it connects to. Screenshots of apps you like help too.

If you already have an app, send access to the code repository and to App Store Connect. The review then covers the current state of the app as well as the new work.

What hiring costs

Carvalho Karsten prices by project, not by hour. The price comes from the project review, which lists the development stages, integrations and changes your app needs.

As a market reference, a native iPhone MVP built by a US-market studio usually costs $50,000 to $100,000. The app development cost guide explains what moves that number.

When an iOS developer for hire is not the right fit

Hiring Carvalho Karsten is not the right choice in two cases. If you need Android at launch, a cross-platform team is a better fit; the native vs cross-platform guide explains why. If you need a developer inside your office every day, hire in-house.

Next step

Send a short description of your app or a link to your current code. The reply brings the next steps and the date of your project review. Teams in the US can also read about nearshore app development with a Brazil-based team.

Frequently asked questions

Should I hire a freelance iOS developer or a studio?

A freelancer fits a small, well-defined task. A studio fits a full app, because you get development, App Store submission and maintenance from one team that does not disappear between projects.

What time zone does the Carvalho Karsten team work in?

The team is in Brazil (BRT, UTC−3). That is 2 hours ahead of Boston in winter and 1 hour ahead during US daylight saving time.

How much does it cost to hire an iOS developer?

Carvalho Karsten prices by project, after the project review. As a market reference, a native iPhone MVP usually costs $50,000 to $100,000 in the US.

Who owns the code?

You do. The app lives on your Apple Developer account, and the source code is delivered to you.

Can I hire Carvalho Karsten to fix or finish an existing iOS app?

Yes. The project review starts by reading your current code and App Store status, then lists what needs to change and what it costs.
