Award-winning App for Smart Health Monitoring Devices

Qardio is a US-based manufacturer of innovative solutions for heart health, weight, and blood pressure monitoring. The company has developed a series of clinically validated and award-winning devices that are distributed and appreciated worldwide.


The client was seeking a company to create an up-to-date native solution for iOS and Android mobile and wearable devices that would serve as a companion application for their smart health monitoring appliances.

As the time to market was crucial for the project, the management has decided to hire a team of proficient senior and mid-level engineers that will allow them to minimize time-to-hire and team learning curves and release a high-quality product in the shortest time possible.


After studying dozens of IT outsourcing providers, the client has chosen to go with Intersog. Key reasons for such decisions were fast access to a vast pool of tech talents and considerably lower development cost (the budget was almost halved due to the cost of the Ukrainian IT team being much lower than in the USA). At the same time, Intersog's expertise allowed us to deliver a top-notch solution, while the customer could retain maximum control over the workflow and timeliness and product quality.

The client has highly appreciated the speed of the candidates screening process conducted by our recruiters as well as the proficiency of engineers we supplied for a technical interview with Qardio management. After the team was put together it began working on the client’s application from one of our R&D offices.

The project team consisted of 11 people:

  • Project Manager / Database Designer
  • 3 iOS developers (1 Senior and 2 Middles)
  • 2 PHP developers ( Senior and Middle)
  • Full Stack developer (PHP / JS)
  • Middle Front-end engineer
  • UX/UI and web designers
  • Senior QA specialist


The Qardio App was designed to work flawlessly with the company's proprietary devices such as QardioArm, QardioBase, and QardioCore. After installation, the app asks you to select the gadget you own so that you can get access to functionality tailored specifically to your needs.
