We are a technology agency operating from 2007. Initially, we were known as e4www, but since 2017 we have rebranded into 7apps. Why have we changed the brand? At the beginning we focused on B2B and B2C online platforms, but today most of our projects concern mobile and desktop apps.

Although the brand name has changed, the company’s values have not. We constantly care about being a reliable and punctual partner for our customers and providing them with real business benefits.

That is why we support our customers at each stage of software development and offer an efficient post-implementation service. Besides, we constantly search for and test new ways of improving our products.

What do we specialize in?

Our domain includes dedicated mobile and desktop apps, such as:

  • applications for cost analysis, budgeting, settling up business trips
  • mobile customer relationship management systems
  • data collector software
  • mobile calculators for fitters
  • applications using NFC, iBeacons and RFID technologies

And many other products supporting automation and optimization of processes taking place in companies. We help our customers to define these processes and select a suitable technology. We comprehensively deal with the integration of new solutions with the existing IT infrastructure.

Currently, our strategic direction of development is to provide mobile solutions that extend functionalities of already existing systems of resource planning, warehouse management, sales and production as well as loyalty systems.
