Frequently Asked Questions

How much does mobile or web app development cost?

The investment in your project depends on its scope, features, and integrations. Factors like complexity, third-party services, and team size all play a role. Thanks to our rapid development approach, we can significantly reduce overall costs compared to traditional development, delivering high-quality results faster and more efficiently.

For a more accurate estimate, you can contact us for a custom quote tailored to your project.

How long does it take to develop an app or platform?

Project timelines depend on scope and complexity, but once we finalize requirements, development typically begins within a week. A mid-sized MVP is usually completed and launched in about 10–12 weeks. For precise estimates, we provide a project timeline after the discovery phase.

Do you offer fixed per-project price or hourly partnerships?

Yes. We offer both pricing models depending on the nature of your project.

  • Fixed per-project price is ideal for projects with clearly defined scopes and deliverables.
  • Hourly or retainer-based models work better for ongoing development, product scaling, or when scope evolves over time.

We’ll recommend the most efficient structure during your initial consultation.

What’s included in your project cost?

Our estimates cover the entire development cycle. From strategy, UX/UI design, and development to QA testing and deployment. We also include initial post-launch support to ensure everything runs smoothly. External costs like hosting or third-party tools are billed transparently, so you always know exactly what you’re paying for.

Do you require an upfront payment?

Yes. To secure your project start date, we typically ask for a small deposit before kickoff. The remaining amount is split into milestone payments based on completed deliverables. This keeps both progress and billing predictable throughout the project.

Can I start with a small MVP and expand later?

Absolutely. Most of our clients begin with a minimal viable product to validate their concept and gather user feedback. From there, we can easily extend functionality, integrate new features, or scale to more users without rebuilding from scratch. Our development approach is modular, so growth is seamless.

Do you provide ongoing maintenance or post-launch support?

Yes. We offer flexible support retainers and on-demand maintenance options based on your needs. These can include performance monitoring, bug fixes, feature improvements, and compatibility updates. We can also assist with hosting management and scaling as your user base grows.

Every project we deliver is thoroughly tested and production-ready, but if any issues arise that result from our work, we naturally correct them at no additional cost.

Can you work with our in-house team or external designers?

Yes. We regularly collaborate with internal developers, product managers, and external design teams. You can choose to involve us in a specific part of the process such as backend development, FlutterFlow builds, or integrations, or let us handle the project end to end.

What happens if I need to change the project scope?

We understand priorities can shift. If your scope or timeline changes, we can adjust deliverables accordingly. Our contracts are flexible, allowing you to scale work up or down without losing progress.

Do you offer special terms for long-term partnerships?

Yes. We value ongoing collaboration and offer preferred rates for clients who work with us on multiple projects or long-term retainers. This ensures consistent development capacity and allows your business to scale efficiently while maintaining cost predictability.
