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 Cambridge (145,700 residents) and across England. 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 Cambridge 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 Cambridge 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 Cambridge, 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 Cambridge 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.
Based in Bordeaux, I work with clients all over France and internationally. But distance changes nothing about my level of commitment.
For 12 years, I've been creating iOS and Android apps for SMBs and startups by putting human connection first. I immerse myself in your projects as if they were my own. You have my direct number, we call each other when needed, and we move forward together.
The most important factor for a successful application comes first from a great human relationship. That is the core of my approach.
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 Cambridge, you see absolutely everything that is happening.
To achieve this, we set up simple and highly effective workflows.
Software development is far too often treated as a terrifying black box.
In many traditional projects, you sign a massive specification document, you pay a hefty deposit, and then you just wait. For months, you receive nothing but vague updates. A few reassuring emails. A lot of "trust us, it is coming along great."
And then the day of the final big reveal in Cambridge arrives... and your heart sinks. The product looks and feels nothing like what you envisioned. But it is entirely too late, and your budget is completely gone.
The most important factor: when you work with me, that black box simply does not exist. Everything is entirely transparent.
From the very first day of coding, you have total access to our shared project board. You can see exactly what specific task I am working on today, what was completed yesterday, and what is scheduled for next week.
Building an app is like building a house in Cambridge.
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 Cambridge. 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 Cambridge is equipped with Apple hardware, a native app is the best possible investment.
You will find quotes ranging from low to triple in Cambridge 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 Cambridge, 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 Cambridge 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.
Ready to launch your app in Cambridge?
You have the idea. You know your market in England. 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.
