BLNK - design of iOS mobile application

An iOS mobile application supporting the maintenance of healthy eyesight.

BLNK iOS application

We created the BLNK mobile application for the health of CrustLab employees. The tool is designed to form the habit of eye exercises among people who spend many hours a day working in front of a computer screen.

BLNK principal challenges

The need to create the BLNK application results from the specific work of developers who spend many hours using the computer every day, which can be tiring and really unhealthy for their eyes. We wanted to form a habit of performing eye exercises during work. In order for this to happen, we had to design the simplest UX possible to minimize the number of clicks a user has to make to set up their preferences and start practicing sight with the BLNK app.

How does it work?

The application takes care of users’ eyesight. After logging in to the application, the user sets their own preferences (e.g. daily work time or working days) based on which the application prepares an individual training plan. This is done in the form of a dialogue with the application, which also shows how to use the tool. Operation of the application is based on notifications that the user receives when they should either stop working, perform visual exercise, or use eye drops. The application monetizes users through the possibility for them to buy individual plans on a subscription basis.


We managed to create a design that, in just a few clicks, allows the user to set their own preferences. It provides access to everything that is most important without having overcomplicated interfaces.

Push notifications ensure regularity and actually form the habit of performing eye exercises among our employees.
