App development
for iOS and Android
A fast, user-friendly app for iPhone and Android, connected to your website, webshop or system.
With one modern codebase we build apps that feel native: with push notifications, login, payments and offline use. We take care of publishing in the App Store and Google Play.

Custom apps
An app that fits your business
An app is not a business card but a tool: for your customers to order or book faster, or for your team to get work done on the go.
That is why we start with what the app should achieve for your business, and only then build the screens and features needed to get there.
What you get:
- One app for iPhone and Android
- Design in your brand style
- Connected to your existing systems
- Managed through your own dashboard
- Publishing in both stores
You work directly with the developers who build your app, in Dutch, English or Arabic.

Technology
Proven technology under the hood
We choose technologies that are fast, stable and maintainable for years, so your app doesn’t break after a single Apple or Google update.
React Native & Expo
One codebase for iOS and Android: faster to build, easier to maintain and updates for both at once.
Native iOS features
Face ID, Apple Pay, camera and notifications: the app uses what the iPhone has to offer.
Android
Tested on devices from different brands and screen sizes, with fingerprint login and Google Pay.
Laravel API backend
A secure dedicated API that feeds your app with data and shares the same foundation as your website.
Push notifications (Firebase)
Targeted notifications about orders, appointments or offers, straight to your user’s screen.
Data & sync
Data is stored locally and synced automatically as soon as a connection is back.

Integrations
Your app connected to your whole business
An app rarely stands on its own. Through APIs we connect it to your website, webshop, ERP or accounting, so products, stock, customers and orders are the same everywhere.
When a customer changes something in the app, you see it right away in your admin panel, and the other way round.
We connect, among others:
- Your existing website or webshop
- ERP and inventory systems
- Accounting and invoicing
- Payment providers such as Mollie
- CRM and email marketing
app-sync

3-month warranty
After launch you get a 3-month warranty. If a bug comes to light during that period, we fix it at no extra cost.
Included:

- Crash and error monitoring
- Help with questions from Apple or Google
- Clear handover and walkthrough
