BLNK - iOS mobile app design

An iOS mobile application supporting the maintenance of healthy eyesight by regular excercises.

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 iOS application principal challenges

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

Hi, I'm Adam - CEO of CrustLab

I would love to share my experience and talk about challenges you are facing! Feel free to reach out to me to discuss your ideas and needs for any project.

How does the BLNK app work?

The application takes care of users eyesight. After logging in to the application, the user sets 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, the user receives notifications when he should stop working, perform visual exercise or use eye drops. The application monetizes users through the possibility of buying individual plans on a subscription basis.


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

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