30 minutes, no slides, nothing to prepare.
From concept to publication. One dedicated expert, 12 years of experience.
In short: ios app development for Chicago (2,693,976 residents) means a project driven by a senior expert — not an agency. Direct communication, ownership of the code, published on App Store and Google Play within weeks.
Because iPhone users are used to excellence. If the app does not respect Apple's rules, they click. They quit. They forget.
Yes. Apple processes 100,000+ app submissions per week with human reviewers hunting down bugs and confusing interfaces.
You can invite up to 10,000 external testers via TestFlight before the app is even public on the Store.
The key point is performance. Native guarantees the best fluidity and access to most the iPhone's components (camera, Face ID, etc.).
I can audit the old code, but for the future of your company in Chicago, the standard is now to migrate everything to Swift.
You have to request it online. It is free, but delays vary from a few days to a month. We will do it on day one of the project.
The Apple ecosystem is recognized as one of the safest. Native Swift code inherently eliminates many common security flaws.
Yes. The statistics are clear: iOS users spend 2x more in-app than Android users.
Do not panic. We read the reviewer's report, fix the problem (often a simple line in the description), and resubmit.
Yes. You own the application. It will be published on your own Apple Developer account, not mine.
You want to launch your app.
Spoiler: Apple is not waiting for you.
Apple processes 100,000+ app submissions per week.
And behind this review process, there are real humans clicking, testing, and judging your work.
The key advantage of this strict process is credibility.
When your application is live on the App Store, it is a massive quality guarantee for your clients in Chicago.
It proves that you respect privacy, that your interface is clean, and that the experience is smooth.
But nearly one submission in four is rejected.
A hidden crash. A misplaced icon. A button that does nothing.
The iPhone user is unforgiving. They click. They quit. They forget.
And Apple is even stricter.
iOS development is not just coding for a different phone.
It is adopting an entire philosophy.
Apple's philosophy.
Apple controls everything. The hardware (iPhone, iPad) and the software (iOS).
The key point is that this strict control is a massive strength for us.
Unlike Android, where we have to test on thousands of different screens, the iOS universe is much more constrained.
This allows us to achieve an exceptional level of polish for every screen of your application in Chicago.
To code, we use the official languages: Swift and SwiftUI.
SwiftUI is Apple's modern standard. It is clean, fast, and built to create smooth interfaces.
But code is not everything.
A good iOS app must respect Apple's Human Interface Guidelines.
This is the design bible at Apple.
It dictates the size of buttons, how menus should open, and the margins to respect.
Why does this matter?
Because iOS users spend 2x more in-app than Android users.
They pay more, but they demand a perfect experience.
If your app does not look like an Apple app, the user will feel it immediately.
They will be confused. They click. They quit. They forget.
My job as an iOS developer is to melt your idea into this premium mold.
We create a product that feels native, natural, and reassuring for your target audience in Chicago.
The number one fear when starting an app project is losing control: you sign an estimate, hand over your idea, and hear nothing for three months. The way of working described here exists so that does not happen.
Three rules, the same on every project:
You test the app on your own phone every two weeks.
Chicago work tends to come from established businesses rather than startups, which means there is usually a system already running and the app has to talk to it. The hard part is almost never the app. It is the API you already have, and how much of it we can use as it is rather than rebuilding it.
Most internal APIs were written for a web application on a fast office network, where an oversized response cost nothing. Put the same API behind a phone on a cellular connection in a basement and it takes eight seconds to answer, and the app looks broken while working exactly as designed. So the first real task on a Chicago project is usually measurement rather than design: see what the existing system actually returns, how fast, and decide what to fix on the server rather than paper over on the phone.
The second recurring question is what not to move. A mobile app that tries to reproduce a whole business system always fails — the screen is small, the user is standing up, and they have one free hand and thirty seconds. What works is three or four actions performed fifty times a day: log a job, confirm a delivery, look up a customer, photograph a document. Everything else stays on the desktop, and saying so plainly at the start saves the argument later.
Chicago's logistics and manufacturing base adds the field constraint on top: warehouses, yards and trucks, where signal is unreliable and the phone is not a desk. That pushes the same way every time — full offline capability with automatic sync, large touch targets, minimal typing, and no data loss if the device dies mid-entry. Those are architectural decisions made in week one, not features added in month four.
With Invent Better, the person who understands your project is the person who writes it. No sales representative, no account manager in between, no handover between three teams. You talk to the developer from the first call through to launch. On a first product, where most of the decisions are made in the first six weeks, that proximity is worth weeks of calendar time.
You do not just hack together an iOS app.
To provide a smooth experience for your users in Chicago, you must use the right tools.
In short, here is what happens under the hood.
I develop primarily in Swift.
It is the modern language created by Apple to replace the old Objective-C.
It is fast, secure, and prevents many crashes.
To build your screens, I use SwiftUI.
This is the future of design at Apple.
It allows us to create animated and responsive interfaces that adapt perfectly to all iPhone and iPad sizes.
For storing the data of your users in Chicago, I integrate Core Data or CloudKit.
CloudKit is Apple's vault in the cloud.
Many app projects fail at the App Store door.
Apple is strict.
The most important factor for success is understanding their expectations.
From the very beginning of our collaboration in Chicago, we integrate Apple's rules into your specifications.
No hidden external purchases. No notification spam. No tracking without consent.
Once the foundation is sound, development begins.
I code in iterations. This means that every two weeks, you see the project progress.
How? Via TestFlight.
You open TestFlight on your iPhone, download the update, and test it at home in Chicago.
You see exactly what you are paying for.
When the application is ready, we prepare for the big leap.
App Store Connect requires special attention.
You need the right screenshot sizes, precise text, and above all, you must complete all legal privacy requirements.
The review process by Apple takes a few days.
They test on real devices.
Apple processes 100,000+ app submissions per week, so we must be flawless to avoid wasting time.
As soon as the green light is given, your app becomes available to the whole world.
The healthcare sector demands absolute rigor.
Here is a case that comes up often: a connected medical tracking app.
On iOS, health has its own ecosystem: HealthKit.
The goal was to synchronize Apple Watch data (heart rate, sleep) with a simple and secure patient interface.
The key advantage here is the data protection offered by Apple.
We built a completely native architecture in Swift.
Security and privacy had to be flawless to pass the App Store review.
Apple is extremely strict about medical apps. nearly one submission in four is rejected, and this number is even higher for healthcare.
So we bulletproofed the permissions and the privacy questionnaire on App Store Connect.
The application was tested intensively via TestFlight by a small panel of patients.
The result?
Apple approval secured on the first try.
Today, the app holds a 4.8/5 rating on the App Store, driven by the ultra-smooth experience typical of iOS.
This is the level of excellence I apply for my clients in Chicago.
Quotes for an iPhone app can vary by a factor of three, which mostly tells you they are not describing the same work. A very low price usually means no real Swift expertise and no working knowledge of App Store review. The cost of a rejected submission is not the rebuild — it is the launch date you miss.
You will find quotes ranging from low to triple in Chicago for an iOS application.
If someone offers you an iPhone app at a ridiculously low price, be careful.
Creating for Apple requires real technical expertise in Swift and a perfect knowledge of the App Store.
In short, you do not just cobble together an iOS application.
Apple processes 100,000+ app submissions per week.
Their teams will not hesitate to block poorly finished or non-compliant apps.
A low-cost developer will ignore these rules to move faster.
Certain business models naturally align with the Apple universe.
In short, here is why these sectors prioritize the iPhone.
A clientele traveling with a significant budget often owns an iPhone.
The native iOS interface allows for a smooth booking experience, rich notifications with images, and ultra-precise geolocation.
Apple processes 100,000+ app submissions per week, and smooth travel apps are always highlighted.
The continuity between the Mac, iPad, and iPhone is Apple's great strength.
If you create a productivity tool for businesses in Chicago, the iOS app is the gateway.
Executives run their companies from their iPhones.
Ordering a car, a meal, a cleaning service.
Apple Pay integration reduces payment friction to zero.
The user does not type their credit card. They validate with Face ID, and the service is ordered.
Twelve years ago, I launched my very first mobile application. Phones have changed since then, but my job remains the same: turning ideas into concrete tools.
From my office in Cannes, I help entrepreneurs and SMBs design iOS and Android apps that make real sense. I don't just code for the sake of coding. I try to understand your business, your users, and your actual needs.
My goal is simple. Build an application that people will actually want to use every day. The key point: we build for them, not for us. Let's talk about yours.
Ready to launch your app in Chicago?
You have the idea. You know your market in Illinois. Now, it is time to take action.
But not just in any random way. The key advantage of working together is absolute clarity. I will not sell you useless features. I will not make empty promises that I cannot keep.
30 minutes to start
Book →Most of my projects run remotely, and in practice that changes very little. We talk over video whenever you need to, not only at major milestones, and you can reach me with questions at any point during the project — I always answer.
Once we are working together, travelling to meet you on site can absolutely be arranged if your project calls for it. Travel costs are quoted separately, upfront and with no surprises.
