What we do02

As an app agency: development that actually works

We build what others overcomplicate. From analysis and architecture to design, code and automation – every piece fits together.

Product Discovery

Every project starts with a business analyst on board. We gather requirements, write user stories, design the database architecture and build a functional prototype – so you can see how your idea works in practice. That way, your app project has a clear structure from the very start.

UX/UI Design

Once the foundation is in place, we turn structure into experience. Our designers create a complete design prototype – from wireframes to polished mobile screens with UI kits, style guides and a consistent design language.

Low-code development

We build apps fast and stable. Having your app built by us means FlutterFlow for the speed of low-code plus the freedom of custom code. Our full-stack developers extend FlutterFlow with Python backends whenever needed.

Automation

We build smart automation that fits your product. With AI agents, n8n and custom API integrations, we connect data and workflows into one seamless flow – stable under load and growing with your app. Ideal if you want to build an app for your business.

Launch & Growth

We take your product all the way into the Apple App Store and Google Play and make sure the review goes smoothly. After go-live, we keep an eye on performance, ship updates and keep improving the product.

Our process03

How our app agency works – step by step

From idea to launch: here's what happens while your concept turns into a finished product.

  1. Free initial consultation

    Together we dive into your idea, sketch the first user flows and show you how your product takes shape. You get structured insights and a clear plan for the next steps – with no obligation.

  2. Product Discovery

    We define the business process logic, design the database architecture and write detailed user stories and software requirements. Your idea becomes a solid technical foundation.

  3. Project estimate

    The team breaks the project down into tasks and scope. Priorities, development costs and a realistic timeline – transparent and easy for you to follow.

  4. Design

    From wireframes and moodboards to a complete design concept and prototype. Our design team works through UI/UX design, creating clean visuals, a smooth flow and a consistent UI kit.

  5. Development

    We use FlutterFlow to build core features and the interface quickly – without sacrificing quality. For more complex logic, we extend the stack with Flutter and Python. You also get an admin dashboard so you can manage everything yourself.

  6. Launch

    Your product goes live on the Apple App Store and Google Play. We prepare the listings, set up integrations and make sure everything works on real devices. After release, we monitor early performance.

  7. Ongoing support

    After launch, your product keeps evolving. Our team handles updates, performance checks and QA audits – so the product stays stable as your user base grows.

Why Xmethod04

An app agency you can trust – and stay in control of

Every step is visible. Every hour is logged. Every build goes from idea to production – with no hidden surprises.

Most products go live within 1–3 months. We build MVPs that don't wait for perfection. They reach the stores, win real users and pay off from day one. For anyone who wants an app built without waiting forever.

Full transparency

You see everything we see. Weekly reports, time tracking, full access to Jira, Confluence and Everhour. Every hour, every task – open, visible and under your control.

Pay for actual work

You only pay for work actually done. No inflated estimates or safety buffers – just the real hours our team spends on your product. Every minute is traceable.

In-depth analysis

Every project starts with Product Discovery. We help you understand your product better – how it works, what it needs and what it can become. Everything is made visual: logic, diagrams, architecture.

Industry expertise

We work across industries, but we're especially strong in health, wellness, sports and fitness. As an app development company with years of experience in these fields, we know how to build products that keep users engaged, stay compliant and perform over time.

Low-code flexibility

The best of both worlds: the speed of low-code tools and the depth of full-stack development. With FlutterFlow, Dart and Python, our apps run on iOS, Android and web. You get custom-level performance at a lower cost. If you're looking for flexible, experienced app developers, you're in the right place.
