About Company

We transform ideas into digital products on time, with no pain. Our agile process is centred around transparency and fast progress while offering high levels of quality and services. In order to build something you need to understand how it works, that is why we do everything in-house. Moreover, we are here to assist you during all your expedition from idea to app stores.

Our process is our secret recipe


We are avid users of scrum methodology and task tracking tools. You can monitor which part of the project is currently under development in real time. Moreover we also offer a CI/CD pipeline which means that you can play with the latest version of the app anytime you like.


Mobile applications are our passion. Our focus is on building outstanding and performant mobile apps. We have a proven track record of over 10 years in the industry and our developers have build apps in the domains of e-commerce, navigation, cryptocurrencies, home automations & IoT, AR & VR, transportation and live audio and video streaming. We are masters of mobile software architectures and low level programming which makes our apps flexible and performant.


All the development is done in-house which means we can answer all the questions about your project and provide status updates or assist you into fixing any struggles which you might encounter. The best part is that we offer this 24/7, which means you can contact us day’n night and we’ll be there for you. We will have overlapping working hours no matter where you’re located.
