Mobile app development

Android apps with React Native and Expo, connected to a database and with user accounts. We know the whole process because we published our own.

What we can build

  • Customer apps: orders, bookings, catalog or tracking.
  • Internal apps for staff: inspections, logs, field tasks.
  • Apps with sign-in, profiles and synchronized data.
  • Versions that share logic with a web portal or management panel.

How we build them

We use React Native with Expo, which lets us write the app in JavaScript, and Firebase for users and data. To publish on Google Play we also prepare the privacy policy and account-deletion page the store requires.

Our own app, Centify, is a personal finance app published on Google Play. That experience is what we apply to client projects.

What to know before starting

  • The Google Play developer account has its own fee and must be in the client's name.
  • Google reviews apps before publishing and may request changes.
  • For now we build Android apps. If you need iOS, we discuss it before quoting.

How the process works

  1. Definition

    What the app does, for whom and what data it handles.

  2. Screen design

    We show you how it will look before coding.

  3. Development and testing

    We build and test on real phones.

  4. Publication

    We prepare the store listing, legal texts and submission.

Frequently asked questions

How much does an app cost?

It depends on its features. Each app is quoted individually once we know the scope. Write to us for a written proposal.

Do you also build the web version?

Yes. An app and a web portal can share the same database.
