Native SwiftUI screens
iPhone screens built with SwiftUI, UIKit where a control needs it, and Dynamic Type for readable text.
The Problem
iPhone Apps Stuck Between a Freelancer and the App Store
iOS projects stall in predictable places: a wrapped website Apple's reviewers reject, a developer account in someone else's name, or a build from an Xcode version App Store Connect no longer accepts.
01 · Account control
Your Apple Developer account belongs to a former freelancer.
We enroll you in the Apple Developer Program and build under your account.
02 · Old toolchain
The last build used an Xcode version Apple now refuses.
Every build uses the Xcode and iOS SDK that App Store Connect currently requires.
03 · Web view app
Half the screens are a wrapped website reviewers can flag.
Screens are native SwiftUI, so the app behaves like an iPhone app.
04 · Login rules
Google sign-in ships without the login option Apple requires.
Sign in with Apple and in-app account deletion go into the first sprint.
Your iPhone app was nearly done. Then your freelancer went quiet, and you found out the Apple Developer account is in their name, not yours. The last build used an Xcode version App Store Connect now refuses. Half the screens are a web view, which Apple's reviewers treat as a repackaged website. Google sign-in works, but the privacy-friendly login option Apple asks for is missing, and so is account deletion. You don't need more code. You need control of your own app.
We start by putting you in control: the Apple Developer Program enrollment in your name, the code in your repository, and a build on the current Xcode. Then we build in Swift and SwiftUI, send TestFlight builds to your iPhone as features land, and plan Apple's review rules into the first sprint. Your app reaches review ready for it, not patched after a rejection.
Your Apple account, your code
Enrollment, certificates, and the repository stay in your name from the first week.
Native Swift and SwiftUI
Real iPhone controls, gestures, and accessibility from Apple's own frameworks, not a web view.
Review rules planned early
Login options, privacy labels, and account deletion are built in before the first submission.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built apps, websites, and software for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Founders Trust Us With Their iPhone App
Your iPhone app depends on Apple's accounts, tools, and review rules as much as on code. These habits keep all three in your hands.
Your Apple account from day one
We enroll you, or your company, in the Apple Developer Program and work as invited team members. Nobody can hold your app hostage when a contract ends.
Current Xcode, every build
We build with the Xcode and iOS SDK that App Store Connect currently requires. Your next update won't bounce because of an outdated toolchain.
SwiftUI first, UIKit when it helps
SwiftUI keeps screens quick to build and change. When a control or an older iOS version needs UIKit, we use it instead of fighting the framework.
Tested on older iPhones
We test on the oldest iPhone your app supports, not only the newest model. Small screens and slower chips show problems a simulator hides.
Privacy details written early
We list what your app and its SDKs collect while we build, not on submission day. Your App Store privacy labels then match what the app really does.
Straight advice on Swift or not
If your users are split between iPhone and Android, we'll say a cross-platform build may serve you better. You pay for native only when it earns its keep.

Good fit
Founders launching iPhone-first
Your early customers mostly carry iPhones, and you want a native app in the App Store before you fund an Android version.
Businesses inheriting an iOS app
Your previous developer left, the Apple account isn't in your name, and the app needs an update before Apple's next build deadline.
Apps built on Apple features
Your app depends on HealthKit, Apple Pay, widgets, or StoreKit subscriptions, and a plugin-based cross-platform build keeps getting in the way.
Teams that need Swift help
You need to hire iOS app developer help for one feature your team can't cover, such as subscriptions or an iPad layout.
Agencies without iOS staff
Your agency sells iOS mobile app development services but has no Swift developer, and the client expects a native app under your brand.
Not a fit
Even Android audience
Your users are split evenly between iPhone and Android, and you want one budget for both. Our Flutter App Development Services page covers one codebase for both stores.
Screens before code
You need tested screens and a prototype before choosing who builds. Our Mobile App Design Services page covers design on its own.
Budget under $1,250
Your budget is under $1,250, or a mobile-friendly website covers what your users need. A responsive site costs far less than an app.
AR or 3D game
You're building an AR experience or a 3D game. Our AR VR App Development Services page covers immersive builds, and game studios suit full games.

Developing an iOS app with DeveloperLook starts at $1,250 for a SwiftUI prototype of your core flow, running on your own iPhone. A native iPhone app with sign-in, push, and App Store release starts at $4,600, and an iPhone and iPad app with subscriptions starts at $8,900. Apple's developer membership costs $99 a year, paid by you. You get a fixed quote after a free call.
Most native iPhone apps take 8 to 12 weeks from the first call to App Store release. iPad or subscription apps take 12 to 16 weeks. The prototype takes about 2 weeks. A company enrolling with Apple needs a D-U-N-S Number, which can add days, so we start it in week 1. We also leave a buffer for questions from App Review.
iOS app development is building software for iPhone and iPad with Apple's tools, then publishing it through the App Store. Developers write the app in Swift, usually with SwiftUI for screens, test it in Xcode and TestFlight, and submit it for Apple's review. The work continues after launch, because Apple ships a new iOS each year and App Store Connect raises its build requirements.
iOS app development is worth it when your customers use iPhones and come back often enough for an app to beat a mobile website. Bookings, subscriptions, health tracking, and loyalty apps usually qualify; a one-time visit rarely does. A good iPhone app development company should tell you which side you're on. If a responsive site covers it, we'll tell you before we quote.
A simple iOS app is manageable for an experienced Swift developer; the hard parts sit around the code. You need a Mac with Xcode, an Apple Developer account, signing certificates, privacy labels, and a build that meets Apple's review guidelines. Subscriptions, offline sync, or HealthKit add real complexity. First-time teams often lose more time to setup and rejections than to the screens.
Swift is the main language for iOS app development, and Apple's own frameworks are designed around it. SwiftUI builds the screens in Swift, while UIKit covers older or highly custom interfaces. Cross-platform apps use other languages: Dart for Flutter and JavaScript or TypeScript for React Native. Those still produce an iOS app, but reach Apple features through plugins or native modules.
Native iOS apps are written in Swift, or in Objective-C for older codebases. We write new code in Swift and SwiftUI, and we can extend an Objective-C app without a full rewrite, since both languages work in one project. When we take over an older app, we first check that it builds with Xcode 26, which App Store Connect has required since April 28, 2026.
iOS apps are usually quicker to test, because Apple makes far fewer device models than the many Android manufacturers. Android is cheaper to start: Google Play charges a one-time $25 fee, while Apple's membership is $99 a year. Publishing differs too. Apple reviews every update, and new personal Google Play accounts must run a 14-day closed test with 12 testers first.
Yes, you can build and test an iOS app on your own iPhone with a free Apple Account, but you can't publish it. Xcode's free Personal Team allows 3 devices, and the app stops opening after 7 days until you reinstall it. TestFlight and App Store release need the Apple Developer Program at $99 a year. We set that account up in your name.
You transfer an iOS app in App Store Connect: the current Account Holder starts the transfer, and the receiving Account Holder accepts it. The app needs at least one released version and can't be in review or pending release. Reviews, ratings, and the bundle ID move over, but code, certificates, and push setup don't, so we rebuild those under your account.
