We also design your mockups, before development starts.

A bigger project?

We keep scopes focused to guarantee speed and quality. Tell us what you're building: we'll look at its scope and propose a first version you can ship in 2 weeks.

Tell us about your project

You bring the idea.
We handle the rest.

  1. 01 — Define

    We make the mockups, or you bring your own.

    We turn your idea into precise mockups that define exactly what we're going to build.

    Already have mockups? We start from those.

  2. ProgressDay 9 / 14
    • App skeleton
    • Accounts and sign-in
    • Core features
    • Notifications

    02 — Build

    We build your app.

    Once everything is defined, we turn your mockups into a complete app, ready to publish, in 2 weeks.

    Your mockups are the reference throughout the build, and we handle the engineering.

  3. Live

    03 — Ship

    We take your app to production.

    The source code is yours, with everything needed to run your product.

    We put your app live and help you publish it on the app stores.

Frequently asked questions.

Still have questions?

Talk to us

Yes.

Highway relies on precisely defined scopes and a development method designed for speed, with no compromise on quality.

The 2-week build starts once the scope and mockups are approved.

We build complete apps, ready to publish, for iOS, Android, the web and desktop.

The Highway format is especially suited to focused products with a clearly defined scope.

Before starting, we define with you a scope we know we can build properly in 2 weeks.

If your project goes further, we split it into several sprints, each with its own price and date: the first delivers the core journey, the next ones add the rest.

No.

You can bring your own mockups, ready for development, or we can design the product with you before the 2 weeks begin.

No.

The €12,000 Highway project starts from approved mockups.

If you need product design and mockups, we handle them in a separate phase, before development.

Yes.

Once the project is completed, the complete source code is yours.

Yes, when required by the project.

Database, authentication, APIs, payments, notifications: we handle common backend needs, within the agreed scope.

We can prepare your app and submit it to the stores, if needed.

Review times depend on Apple and Google, so approval isn't part of the 2-week commitment.

We support you up to launch.

If you then want to evolve your app, we continue together with new sprints or monthly maintenance.
