You want to solve issues or create value?

With a rich portfolio of created application across industries, we know what it takes to build an app that fits your goals, users, and market.

Disconnected processes slowing you down?

Using multiple tools that don't communicate creates inefficiencies. With custom apps we help you unify workflows and boost efficiency.

Generic solutions limiting your growth?

Off-the-shelf solutions can be limiting, inflexible, and costly. A tailored application adapts to your business, scales with you, and eliminates rising costs.

Wasting resources with manual tasks?

Repetitive tasks eat up time and can result in errors. We create purpose-built solutions that automate your operational, keeping everything accurate and fast.

You are making decisions blind?

When decision-making relies on outdated or scattered data, progress slows. With a custom app, we can help you gather the right data, when and where you need it.

Frequently asked questions

Depending on project requirements and mobile application complexity, certain functionalities or their implementation may fall outside the price range listed in our pricing guide. The listed price represents the average cost of services included in the package, but the final quote may be somewhat lower or higher depending on your specific business needs

Mobile application delivery time depends on design complexity, number of functionalities, required integrations, and the package level that suits your business. On average, it takes 3 months to launch a simple application, 5 months for applications of average complexity, and anywhere from 8 to 12+ months for complex applications. We'll determine a more detailed delivery estimate after our initial meeting.

Required documentation varies depending on the app's purpose - whether it's intended for your clients, internal use, or both. Regardless of details, you'll need to prepare an app description with a list of desired functionalities and possible integrations as a starting point for our collaboration. If you have planned branding for the app, you'll also need to prepare graphic components such as logos, brand guidelines, and other supplementary documentation.

Regardless of the service package level, we provide complete initial support during and after the app launch. If you want to continue app maintenance and retain ongoing support, we offer this as a separate service.

This Mobile App Development Package offers a comprehensive approach to developing cross-platform applications that don't exceed a predetermined budget. Through our predefined service package, we cover the entire app development process from initial meeting to launch and post-launch support.
