iOS and Android from one codebase
React Native development: one team, one codebase, two applications. The budget of one app instead of two, and fixes land on both sides at once.
Mobile app development in Tunisia
Belia IT designs, builds and publishes iOS and Android applications from Tunis: business apps, customer apps, marketplaces. One codebase, two stores, a team you can reach.
A mobile app is only worth building if it does something a website cannot: work without a connection, push a notification at the right moment, scan a barcode, track a delivery route, remember a user for months. If your need fits inside a well-built mobile website, we will say so — it costs less and updates without waiting for Apple's review.
When an app is the right tool, we build it in React Native in the large majority of cases: one shared codebase for iOS and Android, so roughly half the budget and timeline of two native apps, with performance that is indistinguishable from native for a management, ordering or tracking application. Native stays on the table when the project genuinely demands it — video processing, heavy sensor use, games.
What a Belia IT mobile app includes
Publishing to the stores
Developer accounts, App Store and Google Play listings, screenshots, privacy policy, and management of Apple's review process. We handle the launch, not just the code.
Push notifications and offline mode
Targeted push notifications, deferred sync and operation without a connection — essential for field use: delivery, stocktaking, meter readings, customer visits.
Custom API and back office
The app ships with its REST API and its admin interface: you manage content, users and data without depending on us.
Usage tracking and maintenance
Privacy-respecting analytics, crash reporting, and compatibility updates for each new release of iOS and Android.
Why build your app with Belia IT
A budget sized for Tunisia
Costed in dinars, with scope cut into successive releases: a first useful version in production, rather than a three-year specification that never ships.
You own the code and the accounts
The repository, the App Store and Google Play accounts and the API are in your name from day one. You are not captive to anyone.
A team that speaks your language
French, Arabic or English, in Tunis or by video. Your end users too: the app can ship bilingual with a right-to-left Arabic interface.
Delivered, not just developed
Plenty of apps die at the publishing stage. Getting live on both stores is part of the engagement, Apple review included.
How a mobile project runs
1. Scoping and user flows
We define together what the first release does, screen by screen — and above all what it does not do yet. That is where the budget is decided.
2. Mockups
The key screens are designed and signed off before any development. You see the app before it exists.
3. Build and testing
Regular builds you install on your own phone through TestFlight and Google Play internal testing, so you test in real conditions.
4. Launch and follow-up
Release on the App Store and Google Play, monitoring of early feedback, fixes, then further versions.
What a mobile app costs in Tunisia
A mobile app is costed after scoping: the price depends on the number of screens, the connections to existing systems and the level of design work. A first useful version, published on both stores, sits at the business application package level, from 6,590 TND excl. tax. Scoping and the quote are free.
See packagesNative app, React Native or PWA?
The right choice depends on the features the app needs and on the starting budget.
| Approach | Ideal for | Limitation |
|---|---|---|
| React Native (iOS and Android, one codebase) | Most business apps: sales, booking, tracking | A few very phone-specific features require native code |
| Native (Swift, Kotlin) | Advanced graphics performance, intensive use of sensors | Two apps to develop and maintain |
| PWA (installable website) | A simple service, without going through the app stores | More limited phone features, especially on iPhone |
Costs to plan for on top of development
The development price is not the only item in an app's budget.
- Store developer accounts: Apple charges every year and Google Play once when the account is opened (about 99 USD per year and 25 USD once, public rates that may change). They are opened in your name.
- Hosting for the back office and the API, depending on the number of users.
- Third-party services: notifications, maps, SMS, payment.
- Maintenance: iOS and Android updates, fixes, enhancements.
Mobile development — frequently asked questions
How much does mobile app development cost in Tunisia?
A first version published on the App Store and Google Play starts at Belia IT's business application package level, from 6,590 TND excl. tax. The final price depends on the number of screens, the integrations (payment, ERP, delivery) and the design workload. The costing is firm after scoping, and VAT at 19 % is added on the invoice.
Native or React Native?
For a management, ordering, booking or tracking app, React Native gives users the same result at close to half the cost, since one codebase serves both iOS and Android. Native is justified for video processing, intensive sensor use or games. We decide at scoping, not on principle.
How long does it take to build an app?
A first useful version generally takes 8 to 14 weeks including scoping and design. Apple's review adds a few days at the end. Later versions ship in two- to four-week batches.
Who owns the App Store and Google Play accounts?
You do. Developer accounts are opened in your company's name and we work in them as collaborators. That is what guarantees you can ship an update even if you change supplier.
Can the app work without a connection?
Yes, where the use case demands it — delivery, stocktaking, field readings, customer visits. Data is stored on the device and synchronised as soon as the network returns, with conflict handling.
Mobile app, responsive site or PWA: which to choose?
A responsive site is enough if your visitors come from Google and do not need phone features. A PWA adds installation on the home screen. An app published on the stores is justified for notifications, offline use, the camera, location or daily use. We advise you to choose the simplest solution that meets your need.
What costs are there after the app goes live?
Store accounts, server hosting, any third-party services and maintenance. We cost them from the scoping stage so that the annual budget holds no surprises.
What types of apps can you develop?
Business apps (tracking, field work, management), ordering or booking apps, customer apps connected to a website or an ERP, and platforms with a back office. The free scoping session lets us confirm what is realistic within your budget.
