The most common thing we hear from founders who have talked to other app shops: "They quoted me 16 to 22 weeks." Our EdTech client heard that from two agencies before coming to us. We shipped idea-to-App Store in six weeks.
The difference is not cutting corners. It is understanding what actually drives the timeline, and cutting the things that do not.
What a realistic iOS app timeline looks like
For a focused, well-scoped iOS app with a backend, App Store submission included, the real range is:
- Simple app, defined scope, no novel UI: 4 to 8 weeks
- Medium complexity with API integrations and custom flows: 8 to 14 weeks
- Complex app with novel features, custom hardware, or heavy real-time requirements: 14 to 24 weeks
The 16-to-22-week quotes our clients kept hearing were for medium-complexity apps. They are not unreasonable. But they are often padded with discovery phases that could be compressed, design rounds that run long because nobody made a decision, and review cycles that stack up because the client is not available.
The three things that actually determine your timeline
Scope clarity at the start. Every week spent in "discovery" after kickoff is a week the engineers are waiting. The clients who ship fastest come in with a clear problem statement, a defined set of must-have features, and a willingness to defer the nice-to-haves to version two. You do not need a complete spec. You need a clear scope.
Decision speed on the client side. Design reviews that take two days are half the cost of design reviews that take ten days. This is the most controllable timeline variable and the one most project estimates ignore. If you can commit to reviewing and responding to work within 24 to 48 hours, you will compress your timeline by weeks.
The authentication and backend architecture. If your app shares auth with a web product or requires a custom backend, that decision shapes the first two weeks of development. Apps that use an existing identity provider (Supabase, Firebase, Auth0) and simple REST APIs ship faster than apps that need a custom auth system built from scratch.
What the App Store review adds
Plan for 2 to 7 days of App Store review time. Apps that follow Apple's guidelines closely, use standard APIs, and have complete and accurate privacy declarations pass on the first attempt most of the time. Apps that push boundaries on permissions, have incomplete metadata, or use anything that looks like a private API often go back for revision.
We target first-pass approval on every submission. The way you get first-pass approval is boring: follow the guidelines, complete the privacy nutrition label accurately, test on a real device running the release build (not the simulator), and read the rejection reasons from the previous submission if you have one.
What things actually cost
For a Kansas City business or funded startup in 2026:
A native Swift iOS app with a simple backend and App Store submission: $15,000 to $35,000.
Add an Apple Watch companion app: add $5,000 to $12,000.
Add an Android version: add 60% to 80% of the iOS cost if built in native Kotlin, or less if cross-platform with React Native.
Full-stack builds with custom backend, auth, admin dashboard, and both iOS and Android: $50,000 to $120,000 depending on feature scope.
The gap between the low end and high end of each range is almost always: how clear is the scope, and how fast can the client make decisions.
What to ask any shop before you hire them
Ask to see the last three apps they shipped, the actual App Store links, and the timeline from kickoff to submission. Ask what the most common reason is for a project running late. Ask who the lead developer on your project would be, not the person you are talking to in sales.
A shop that has shipped apps in the last six months will answer these without hesitation.
We build iOS apps from concept to App Store, with Apple Watch support where it fits. Start a project and we will scope the build in one conversation.
