I created a tool where you just click a button and it records your in time and keeps in the local storage of a browser.

It gives you remaining time in office plus when will be your half day or short day based on your in-time. Whenever you visit in a whole day.

For motivation, I mention the remaining time in office like. Ex. "10 minutes more in the office or 1 more hour".

I shared this with one or two of my colleagues and within in a week, I saw it open in every sales, HR and IT departments systems.

That day I get the taste of true entrepreneurship.
