What's included

What you get

Every item goes into the scope document before we start, so you know exactly what you will receive and when.

  1. Android and iOS from one codebase

    We build the app with Flutter, so you get both versions in less time and at a lower cost than building each one separately.

  2. Connected to your system or store

    The app runs on the same data as your website or system, so you don't manage products or customers in two places.

  3. User notifications

    An alert about a new offer, an order status or an appointment, delivered straight to the user's phone.

  4. An admin dashboard

    Manage the app's content and users from it, without releasing a new update each time.

  5. Publishing on the stores

    We prepare the app's store listing, upload it to Google Play and the App Store, and follow the review until it goes live.

  6. For your customers or your team

    An ordering or booking app for your customers, or an internal app for your sales reps and field technicians.

FAQ

Questions about Mobile Apps

Straight answers to what business owners ask us most before they start.

How much does a mobile app cost?

It depends on the number of screens and the integration needed with your system or store. We set the price after a short session to understand your app idea, and write it in a clear quote with the scope and timeline before we start.

Do I need an app, or is a website enough?

If your customers visit you once, a fast website is usually enough. An app pays off when users come back often: repeat orders, bookings, status tracking or notifications. We help you decide in the first session.

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

Yes. We prepare the store listing, upload the app and follow the review. Ideally the developer account is in your company's name, so the app stays under your ownership.

Will the app connect to my current system?

Yes, if your system allows integration. If it doesn't, we build the part the app needs and write it into the scope.

How long does it take?

From 3 to 10 weeks depending on the number of screens and integrations, plus the store review time before the app goes live.

What happens after delivery?

We fix any bug that appears, free of charge, within 60 days of delivery. After that, you can subscribe to monthly support for updates, backups and changes.
