OUR EXPERIENCE

Mobile App Development
We create mobile apps for various platforms using first-class technologies and proven approaches. We develop native apps because we use proven solutions and a set of libraries that we created and maintain ourselves. We write clean and stable code in Swift, Objective-C, Java, and Kotlin. Our smartphone app development services include: native mobile app design and development for Android and iOS, next generation technologies, intelligent algorithms and modern UI, React Native and Flutter based mobile app development.

QA Services
Our QA company is ready to perform full cycle of high quality functional testing of your mobile applications by selecting the required types of services: for example, installation, system or configuration testing, integration testing, cross-platform or localization testing, as well as exploratory testing. Let our testing company perform performance testing and make sure that your digital system can handle the expected loads, determine its maximum load and identify weaknesses in your business project.

Design development
The design process includes three big blocks: analytics, engineering, and design itself. Initially, our experts analyze the product, research market trends, and work out the user's portrait. Next, we apply user scenarios to the interface structure. At this stage, the total number of screens and the approximate content of each screen becomes clear. We clarify the functionality of each screen, draw them schematically. And finally we present the only correct version of the design that perfectly fits the functionality of the application.

Application promotion
After completing the development of the application, we are engaged in its support and promotion. We buy traffic and work with the largest advertising sources, each of which is well proven on the mobile marketing market. Our designers create advertising creatives of any complexity from a static banner to 3D animation. The team of specialists will improve the app's visibility in the App store and Google play, increasing the Install Rate in the app stores.
