Klukk, a free Android app developed by Stokkur Software, is a time registration app designed to help employees monitor their time spent at work. The app is specifically created for ASÍ employees to compare their work hours with the salaries paid. With Klukk, employees can easily punch in and out of work, and the app notifies them when they arrive or leave the workplace, reminding them to punch in or out.

One of the most significant features of Klukk is that it delivers an Excel file to the employee's email address, providing them with an overview of their registered time. Klukk is a useful tool for employees to keep track of their work hours and ensure that they are accurately paid for their time.
