Mobile app development
iOS and Android apps for bookings, orders and loyalty, built from one codebase. Customers keep coming back because your business is right there on their phone.
Why it matters
Getting an app installed is the easy part. Most apps are forgotten within days. Good ones become a habit.
90%
of the time people spend on their phones is spent inside apps, not the browser.
Mobile usage research
25%
of apps are opened once and never used again.
Localytics
77%
of daily users are gone three days after installing an average app.

What is inside
Layer 01
Screens that look and feel right on iPhone and Android, simple enough that nobody needs instructions.
Layer 02
Screens open instantly and key features keep working offline, then sync when the connection is back.
Layer 03
Reminders, offers and order updates sent at the right moment, so people open your app again and again.
Layer 04
Customers book, order and pay inside the app with cards, Apple Pay or Google Pay. The money goes to your account.
Layer 05
See bookings, orders and users in one place, change prices and send offers without calling a developer.
No surprises
One codebase for both stores, so you pay once and every update reaches everyone.
We prepare the listings, screenshots and review, and publish under your own accounts.
Reminders, offers and updates that bring customers back to your app.
See users, orders and bookings, and know which features people really use.
Encrypted data, safe sign-in and privacy settings that follow store rules.

The Discovery sprint takes one week. A first app usually takes 8 to 10 weeks from kick-off to both stores.

Yes. We build both from one codebase, so you pay once and every update reaches all your users.

Online by card or PayPal. The sprint is paid upfront, and builds are paid in parts as we reach each stage.
