    On-time delivery

    Most apps fail. Ours don't.

    80% of apps aren't opened after 3 days. Not because apps don't work, but because they don't solve a real problem. That's why we don't start with building, but with understanding.

    1

    You don't know if your app idea is viable

    2

    Previous apps were delivered too expensive and too late

    3

    Your app needs to work on iOS and Android without double costs

    4

    You want an app that users keep using after week 1

    5

    You don't have a technical background to evaluate vendors

    Why Score

    Fast time-to-market

    From idea to working app in weeks, not months. MVP-first approach to validate quickly.

    User-driven

    We build what your users need, not what we think is cool. Data and research drive our decisions.

    Enterprise-grade security

    Encryption, secure authentication, OWASP-compliant. Your user data is safe.

    The right technology for your case

    In 90% of cases, cross-platform is the smartest choice. One codebase for iOS and Android means faster development, lower costs and easier maintenance.

    React Native

    One codebase, two platforms. 70% faster development.

    Flutter

    Native performance, pixel-perfect UI for demanding apps.

    Swift/Kotlin

    When 100% native is truly needed (gaming, AR, etc.).

    PWA

    Web-first, installable as app. No store needed.
