We are asked:
-
Which business sectors are mobile apps suitable for?
Mobile software is suitable for e-commerce, social online platforms, HoReCa, food delivery, and real estate agencies. Apps can optimize internal business processes as well as interact with clients and audiences.
For example, a restaurant can launch its own delivery service or a loyalty app featuring promotions, bonuses, and games. An online store catalog is easy to browse on a smartphone. To keep clients informed about promotions, push notifications can be integrated — an effective tool to boost sales.
-
Do you develop cross-platform apps?
Yes, we create cross-platform products using React + Capacitor. This technology stack allows us to build a single frontend and adapt it to the UI requirements of both iOS and Android.
-
How much does mobile app development for iOS and Android cost?
The cost depends on your business needs and is calculated individually for each project. To get a preliminary estimate, request a brief from our manager and fill it out. We will provide a detailed quote explaining the scope and nature of the work. -
How long does development take?
It depends on the complexity of the product. The minimum timeline is 3 months. If new features or changes arise compared to the original technical specification, we work iteratively — for example, a project could be planned for 5 years, with phased releases every 6 months.
-
I need the project urgently. Can you prepare it quickly?
Yes, depending on the available resources for custom app development and the project’s requirements. Share your situation details, and we will make every effort to assist you.
-
Do you launch finished products on the App Store and Google Play?
We publish only the apps developed by our company. Usually, the client registers their account in the app marketplaces, but our experts can assist if needed.
-
Do you modify already existing apps?
It depends on the technology stack, product quality, code structure, and number of bugs. In such cases, we perform a technical audit and then decide whether we can take on the modifications.
-
How is the product tested before release?
The QA specialist and project manager prepare test cases and a strategy covering functional, iterative, and load testing.
