An iPhone MVP costs $8,000–$15,000, a full business app $15,000–$40,000, and an enterprise iOS solution $50,000–$250,000 or more. Add $99 a year for the Apple Developer Program, plus hosting and maintenance. You get a fixed quote after discovery.
An MVP takes 6–10 weeks, a business app 2–5 months, and an enterprise app 4–9 months, released in phases. App Review usually adds a few days at launch.
Go native with Swift if the app relies on Apple features, top performance or a premium feel, or if most of your users are on iPhone. Choose Flutter or React Native if you need iOS and Android at launch on a tighter budget.
No company can; Apple makes the final decision. We prepare every submission against Apple's guidelines (stability, privacy labels, privacy manifest, in-app purchase rules and reviewer access), which removes the most common reasons for rejection, and we handle any follow-up with App Review.
The most common reasons are crashes, bugs and apps that feel incomplete. Next come privacy and legal issues, such as missing privacy labels, an inaccurate privacy manifest or no account-deletion option. Design problems also cause rejections, such as an app with too little functionality or one that copies another app. We check each of these before every submission.
Yes. The source code, designs, App Store listing and IP belong to you, and the app is published under your own Apple Developer account.
Yes, before any detailed discussion of your idea.
Yes. We build iPad layouts, watchOS companion apps, tvOS apps and visionOS experiences. Each extra platform adds design and testing time, so we usually start with iPhone and add others in later releases.
We usually support the current iOS version and the two before it, which covers the large majority of active iPhones. We pick the exact minimum from your users’ data. Apple requires new apps and updates to be built with Xcode 26 and the iOS 26 SDK, so every release we ship meets that rule.
Yes. We start with a code and crash review, then fix stability issues, update to the latest SDK, and move Objective-C or UIKit code to Swift and SwiftUI step by step.
Yes, using Core ML and Apple's on-device Foundation Models where privacy and speed matter, and cloud AI for heavier tasks. Typical features are smart search, document scanning, summaries, recommendations and chat assistants.
Maintenance covers yearly iOS updates, crash fixes, security patches and small improvements, usually as a monthly plan. Plan for it from launch, because every September's iOS release can require changes.
Dedicated Swift developers start from $45 an hour, depending on experience and engagement length. You can hire full-time, part-time or for a fixed project.
You get a TestFlight build and a demo every two weeks, a shared Jira or similar board, and a Slack or Teams channel with the team.
