One single point of contact, from concept to publication. 12 years of experience. 15+ apps delivered.
In short: I build iOS and Android apps for clients in Longueuil (249,277 residents) and across Quebec. One single point of contact, 12 years of experience, delivery from concept to publication in 8 to 16 weeks.
You have an app idea.
Let's pause and take a breath.
If your target audience in Longueuil expects premium quality, your choice of platform matters.
The most important factor is knowing where the value is.
iOS users spend 2x more in-app than Android users (Apple, 2025).
It is a matter of logic.
The Apple ecosystem attracts a customer base that is used to paying for quality, subscriptions, and premium services.
If you want to build an iPhone app in Longueuil that generates solid revenue, you need to target the App Store.
But be careful. You do not just walk into Apple's store easily.
You have to respect their rules. Their design standards. Their technical requirements.
I am a freelance iOS developer.
Everyone wants their app on the Apple store.
But publishing an iOS application is a real journey.
Let's pause and take a breath.
The key advantage of this complex process is that it filters out bad apps.
First, there is the creation of the Apple developer account. And here comes the surprise.
If you are a business in Longueuil, you need a DUNS number.
The DUNS is the international ID card of your company.
Getting it can take between 2 and 4 weeks. It is best to know this on day one.
Then, we code. Cleanly. Following the rules.
Next comes the testing phase with TestFlight.
TestFlight is the rehearsal room for your application.
We can invite up to 10,000 testers before the official release.
This is where we hunt down bugs and tweak the experience.
Finally, the final boss: validation by the App Store.
Keep in mind that 40% of first submissions are rejected (Apple, 2025).
A poorly filled privacy form. A poorly explained paid option. A missing test account.
Apple lets nothing slide.
Validation takes between 24 hours and 7 days.
It is a matter of rigor.
This is why having an iOS expert in Longueuil is not a luxury.
I know these rules by heart.
My goal is to help you avoid frustrating back-and-forths with Apple reviewers so your app goes live as quickly as possible.
I build mobile applications the way a craftsman builds a house. With solid foundations.
I've been doing this job for 12 years from Bordeaux, designing iOS and Android apps meant to last. I refuse sloppy work. The key advantage of this method? Your application won't collapse at the first Apple or Google update.
I create clean tools that are easy to maintain and ready to evolve alongside your SMB or startup. Work done with care is a profitable investment for the long run.
I have guided dozens of clients over the past 12 years. And I know exactly what the number one fear is when launching an app project.
It is the fear of losing control.
You hand over your baby, sign an estimate, and then hear absolutely nothing for three months. You become entirely dependent on a technical black box. 🕵️♂️
The key advantage of our collaboration is total transparency.
It is a matter of trust. Even if I am not physically sitting in your office in Longueuil, you see absolutely everything that is happening.
To achieve this, we set up simple and highly effective workflows.
Running an app on iOS requires precision.
The key advantage of native development is full access to the phone's capabilities.
No middlemen. No slowdowns.
The main engine is Swift.
A robust programming language that guarantees maximum performance.
Coupled with SwiftUI, we build the interface for your project in Longueuil.
This is what gives Apple applications that magical feel: smooth transitions, instantly reacting buttons.
If your app lags, the user deletes it.
They click. They quit. They forget.
That is why I always favor the tools provided directly by Apple.
To manage complex data flows, I use the Combine framework.
It is the conductor that ensures your application's information displays without delay.
Before your application reaches the hands of your customers in Longueuil, it goes through TestFlight.
TestFlight allows us to distribute the app to your teams for real-world testing.
It is the essential tool to ensure everything works perfectly before official publication.
And throughout development, I use Xcode Cloud to automate testing.
The goal? To ensure that every new line of code does not break what worked yesterday.
It is a matter of trust.
Building an app is like building a house in Longueuil.
You do not start painting the walls before laying the foundation.
Let's pause and take a breath.
The key advantage of my method is transparency.
Step 1: Scoping.
We define exactly what the app will do. We list the features. And above all, we anticipate Apple's requirements.
Step 2: The developer account.
This is the time to request your DUNS number if you do not have one. It takes time, so we do it right away.
Step 3: Development in Swift.
I code the application brick by brick.
You do not wait six months in the dark. I give you TestFlight access very quickly.
TestFlight is your VIP access.
You install the work-in-progress app directly on your iPhone in Longueuil. You test, you give feedback.
Step 4: Preparation for App Store Connect.
We prepare the screenshots, the descriptions, and the famous data privacy questionnaire.
Step 5: Submission to Apple.
Apple processes 100,000+ app submissions per week (Apple, 2025).
Their team of humans will dissect our work.
The review period generally takes from 24 hours to a few days.
Step 6: The launch.
Your application is on the App Store. It is ready to be downloaded.
It is a matter of method. Zero improvisation.
B2B does not always have to be just web-based.
An industrial company was looking for a solution to equip its sales reps in the field.
They all had iPads provided by the company.
The key point: they needed a robust app capable of working without an internet connection in warehouses.
Forget laggy hybrid web solutions.
We went with 100% native iOS development.
Using Core Data allowed us to store the entire product catalog locally on the iPad.
The interface was tailor-made for the large screen, respecting Apple's strict ergonomic standards.
Deployment was done privately, bypassing the public App Store, using Apple's enterprise tools.
But the quality requirement remained the same.
We used TestFlight to have the pilot sales reps validate each step.
The app never crashes, even during massive data synchronizations.
Sales reps save time. The company increases its sales.
If your sales force in Longueuil is equipped with Apple hardware, a native app is the best possible investment.
You will find quotes ranging from low to triple in Longueuil for an iOS application.
Let's pause and take a breath.
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 (Apple, 2025).
Their teams will not hesitate to block poorly finished or non-compliant apps.
A low-cost developer will ignore these rules to move faster.
The result? You pay, but the app is rejected. And you have to pay again to fix it.
It is a matter of trust.
The budget for an iOS app reflects this level of quality.
It includes assistance in setting up your developer account .
It includes time spent on TestFlight eradicating bugs with you.
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 (Apple, 2025), 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 Longueuil, 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.
It is a matter of trust.
The user does not type their credit card. They validate with Face ID, and the service is ordered.
It is possible. 40% of first submissions are rejected (Apple, 2025). That is why I prepare everything carefully: respecting guidelines, testing, and privacy policies.
It is a global business identifier required to open a professional Apple Developer account. Without it, you cannot publish under your Longueuil company name.
Usually between 24 hours and 7 days. But if the file is incomplete, it can take weeks of back and forth.
It is Apple's official application for testing our project during development. I send you a link, and you install it on your iPhone.
The most important factor is profitability: iOS users spend 2x more in-app than Android users (Apple, 2025).
Only Swift and SwiftUI. Objective-C is the past. Swift is the modern, fast, and secure standard for the Apple ecosystem.
Yes. The Apple developer account requires an annual subscription. It is mandatory to keep your app live.
Absolutely. Apple requires you to declare exactly what the app tracks. A mistake here leads to a direct rejection of the update.
Yes, we can adapt the SwiftUI interface to take advantage of the iPad's large screen without having to recode an entirely different app.
Yes. Apple takes between 15% and 30% on virtual goods and subscriptions sold within the app. It is an unavoidable rule.
