React Native or native (Swift/Kotlin)?

React Native is ideal for a limited budget and launching on both platforms at once. Native (Swift for iOS, Kotlin for Android) delivers maximum performance for complex apps. We recommend based on your specific requirements.

How long does it take to develop an app?

A simple app (3–5 screens) takes 2–3 months. A complex app with an integrated backend can take 4–8 months.

Does the source code stay mine?

Yes, 100%. On delivery you receive the complete source code and access to all repositories.

Can you maintain the app after launch?

Yes, we offer maintenance contracts that include compatibility updates for new iOS/Android versions, bug fixes and new features.

Do you publish the app to the App Store and Google Play?

Yes. We handle full publishing and configuration on the App Store and Google Play, in line with each store's review requirements.

Do you connect it to the web system I already have?

Yes. We integrate the app with your existing backend and systems, with synchronised data. If you also need the full web ecosystem, see the Web Development service.

Why it matters

Your app, right on the client's screen, not just in a browser tab.

Native or cross-platform mobile apps, connected to your systems, built for real-world use, not a website squeezed into a container.

Real native experience: not a wrapped website.
Smart cross-platform: optimised cost with no visible compromises.
Connected to your systems: a single backend, synchronised data.
All the way to the store and beyond: publishing + maintenance, we don't leave you halfway.
In-house & transparent: access to the code, a dedicated team.

What we do

Mobile apps built right from the first iteration

UX analysis and wireframing before a single line of code
Informed choice: React Native / Flutter (cross-platform) or Swift / Kotlin (native)
Design adapted to Apple Human Interface and Material Design guidelines
API integrations, authentication, push notifications, in-app payments
Testing on real iOS and Android devices, not just simulators
Full publishing and configuration on the App Store and Google Play

What we build

Mobile development types

Whatever the industry (e-commerce, medical, fintech, delivery), we build products that connect the user directly with your business.

Cross-platform (React Native / Flutter)

Cost-efficient

We write the code once and ship it on both platforms: cost-efficient, with near-native speed.

Includes:

Much shorter development timeline
A single codebase, easy to maintain
Consistent design on iOS & Android

Native (Swift / Kotlin)

Maximum performance

Developed in Apple & Google's original languages, with full hardware access.

Includes:

Maximum speed and performance
Native integration (Bluetooth, GPS, AR)
The most complex visual animations

Backend & API

The engine

The app is the façade; the engine is a stable cloud architecture where users, payments and critical data live.

Includes:

Documented API
Web admin panel for management
Secure database

Evolving maintenance

After launch

We monitor crashes, add features and adapt the code to every OS update.

Includes:

Compatibility with new iOS / Android versions
Fast resolution of critical bugs
Backend scaling as the user count grows

Mobile UX/UI

Design built for the small screen and thumb use, not a shrunk desktop.

Development

We build in sprints, with builds testable on real devices.

Device testing

We test on real iOS and Android devices, not just in an emulator.

Store launch

Publishing on the App Store & Google Play, with everything each one requires.

Maintenance & updates

Benefits

What you gain with Webbly

iOS and Android

Full coverage on both platforms: native or cross-platform, depending on requirements and budget.

Native UX

We respect Apple and Google guidelines. Users feel the app was built for their platform.

Optimised performance

Fast response times, smooth animations and low battery consumption: the standards we expect from a quality app.

Built-in security

Secure authentication, encrypted data storage and compliance with App Store and Google Play requirements.

OTA updates

Content updates and bug fixes without going through App Store review (where permitted).

Guaranteed publishing

We know the Apple and Google review requirements. We prepare the app to pass on the first attempt.

Quick Clean

From Wix to Next.js, without losing Google rankings

At launch, measured with Google PageSpeed Insights: performance 100 on desktop and 96 on mobile, with 100 for accessibility, best practices and SEO on both. CLS 0. Image footprint cut from 83 MB to about 7.4 MB, a clean architecture with around 22 indexable pages. SEO parity preserved: 1:1 URLs and metadata, 21 verified redirects, validated JSON-LD. Clean cutover: uninterrupted email, HTTPS, zero downtime, with rollback available. Post-migration traffic is in its first observation window (4 weeks against the GSC baseline), with a defined alert threshold; at publication it is too early for traffic figures, and the methodology is built precisely to protect them. The old Wix subscription is closed only after stabilisation is confirmed.
