iOS App Development Services
Writing the app is the predictable part. Apple's requirements, the review process, and the fact that you'll be shipping updates for as long as the app exists are what actually shape the project.
First question
If none of these apply to what you're building, a website will do the same job for a fraction of the cost and none of the ongoing obligation. Worth checking honestly before committing.
Reaching someone when they aren't in your app. The single most common genuine reason a business needs one.
Field staff, warehouses, transport, anywhere signal is unreliable. A site simply stops working there.
Camera used seriously, barcode scanning, background location, Bluetooth, or biometric sign in.
Daily-use tools benefit from an icon people tap without thinking. Occasional-use tools don't.
Heavy interaction, animation, or media where the difference between native and browser is noticeable.
Widgets, share sheets, Apple Pay, and the system integrations users expect from a real iOS app.
If your list came up empty, say so on the call and we'll tell you the same. Plenty of app enquiries turn into a better mobile site, which costs less and doesn't commit you to shipping updates indefinitely. If some of it fits but not all, cross-platform is often the sensible middle.
The part nobody plans for
Every release goes through review, including bug fixes. Usually it's quick, occasionally it isn't, and a rejection resets the clock. Launch dates get planned with that in mind rather than around it.
Placeholder content, broken links, or features that clearly aren't finished. Submitting a half-ready build to save a week reliably costs two.
Anything behind a login needs working test credentials supplied with the submission. Forgetting this is one of the most common avoidable rejections there is.
Digital goods and subscriptions generally have to go through Apple's own purchasing, and Apple takes a share. This changes your commercial model, so it's decided at scoping, not at submission.
What your app actually collects has to match what you declared and what your privacy policy says. Mismatches get caught.
An app that only wraps your website, with nothing a browser couldn't do, is a recognised rejection reason. Worth knowing before you commission one.
Before you can ship
Each of these is small on its own and each one blocks release if it's missing. They get sorted during the build rather than discovered at the end.
Paid annually, registered to your business, and holding your app forever. It should never sit under an agency's account, including ours.
Publicly hosted and accurate about what you collect. Apple also requires you to declare data collection in the listing itself.
Users must be able to delete their account from inside the app, not by emailing support. It affects how accounts are built, so it's a design decision.
If you offer social sign in, Apple requires their own option alongside it. Cheap to include from the start, awkward to retrofit.
Icon, screenshots at the sizes Apple asks for, description, keywords, and an age rating. Usually the thing that delays a submission by a week.
A working support URL or email, and somebody who answers it. Store reviews are public, and unanswered ones sit there permanently.
How a build runs
Simulators hide the problems that matter: slow networks, small screens, low battery, interruptions, and older devices still in daily use.
Phase 01
The smallest app worth downloading. Everything else gets sequenced, because each release costs a review cycle.
Phase 02
Screens and navigation following the conventions iOS users already know, so nothing needs explaining.
Phase 03
Distributed to your team through TestFlight as it's made, on the devices they actually own.
Phase 04
Listing, screenshots, and disclosures prepared, then submitted under your account with a plan for the first update.
Older devices matter more than people expect. A meaningful share of iPhones in daily use are several years old, and an app that only feels good on the newest hardware feels broken to a large part of your audience.
The commitment
This is the part that decides whether an app is a good idea, and it's the part most quotes leave out entirely.
A new version arrives annually and things get deprecated. An app left alone for two years usually needs real work before it can even be rebuilt and resubmitted.
The developer membership renews annually. Let it lapse and your app is removed from the store, which is an unpleasant way to find out.
There's no quiet patch like there is on the web. A one line bug fix goes through the same submission and review as a major update.
Store ratings affect downloads, and unanswered complaints stay visible. If you also need Android, that doubles this work rather than sharing it.
Common questions
Depends on your users rather than on general market share. Check your own analytics for the split, because it varies enormously by country and audience.
If you need both and the app isn't heavily device dependent, cross-platform usually costs less than two native builds and is worth pricing before committing to either.
Too variable for a number here to mean anything. What moves it is the number of screens, whether there are accounts and a backend, and which device features are involved.
Budget for the year rather than the build. The first version is typically a fraction of what an app costs over its life, and planning only for the build is how apps get abandoned.
Technically yes, and it's usually a bad idea. Apple rejects apps that offer nothing beyond the website, and users can tell immediately when they're looking at a wrapped web page.
If the goal is a home screen icon and a faster mobile experience, that's achievable on the web without the store or the review cycle at all.
Rejections come with a reason, and most are fixable within a day or two. The common ones are avoidable, which is why the requirements get handled during the build rather than after it.
If we caused it, fixing and resubmitting is on us. What we can't do is guarantee a review outcome, and anyone promising that is overstating what they control.
Yours, always. We're added to it as a team member, and that access can be removed whenever you like without the app being affected.
Apps published under an agency account are difficult to transfer and easy to lose access to. Not a situation worth being in.
If the app has accounts, syncs data, or shows anything that changes, then yes. That's often half the project and it's frequently missing from app quotes.
If you already have a system the app can talk to, that's a large saving. That side of the work sits with web application development.
If you need both platforms, it's worth comparing two native builds against a single cross-platform one before deciding. Pricing sits on the main app development page.
