What you receive

More than a number on a slide

Every estimate is designed for procurement-ready transparency — scope, architecture, phases, and a clear path to order.

Proof: a shipped product

Fluentico: from specification to a live app

Fluentico is a cross-platform language-learning app built with Flutter. The project started as a Lean Do IT questionnaire and shipped to the App Store and Google Play.

    Delivery model

    Fixed price, full ownership, no surprise fees

    Infrastructure, third-party API usage, app-store fees, and client-supplied artifacts are excluded unless explicitly listed in your offer — matching the disclaimers in your estimate report.

    Capabilities

    Built for real software projects

    The questionnaire captures mobile, web, desktop, and backend layers — plus security, compliance, scale, and QA expectations.

    Why it matters

    Buy software development with evidence, not guesswork

    Lean Do IT is designed for teams who need a credible baseline before signing a contract — without weeks of discovery workshops.
