    FAQ

    How much do mobile app development services cost?

    There is no single price tag for mobile app development. Costs can vary based on your specific needs. The development of a basic application with standard features ranges from $10,000 to $25,000. If you have plans to launch an app of medium complexity with custom features, you may need to invest between $30,000 and $70,000. However, custom apps with advanced AI will be more expensive. The cost of such services can exceed $150,000.

    What factors impact the cost of custom mobile application development?

    The biggest price driver is feature complexity, especially when it comes to AR-driven tools or AI capabilities. Other critical factors include the platform choice (cross-platform development can help you optimize costs), the complexity of the UI/UX design, and third-party API integrations. Apart from this, it is vital to take into account the composition of your development team and the hourly rates of developers in the chosen region.

    How long does custom mobile app development typically take?

    The duration depends entirely on the scope of your project. A simple project can take about 2 to 4 months from start to finish. When your developers are building a medium-complexity app with a custom backend, they may need from 4 to 7 months. However, if you want to launch a feature-rich, enterprise-level application, you need to allocate more time for this project. The process can take from 8 to 12 months or longer.

    What is the usual timeline for a mobile app development project?

    Our custom mobile application development company always breaks the entire process down into several stages. The discovery and design stage usually takes between 4 and 6 weeks. On average, the core development runs for about 8 to 16 weeks. But this stage can take longer, given the complexity of your project. Next, quality assurance testing usually takes 2 to 4 weeks. Finally, deployment and app store approval add another 1 to 2 weeks.

    Does Cogniteq develop apps for both iOS and Android?

    Yes, our custom mobile app development company builds solutions for both platforms. Depending on your specific business goals and target audience, we can develop native apps or offer cross-platform development with modern frameworks like Flutter or React Native. This approach allows us to rely on a single codebase for both platforms. As a result, we can help you save time and money without sacrificing quality.
