Being a student I had many unslept nights by polishing final designs, proofreading reports and preparing for the exams. During this days I drunk many cups of coffee as I believed that I will be able to stay up late. It was wrong, but my body asked for it. And to take care of my body I tried to find applications to count how much caffeine I consumed during the day, but I could not find it. So as a part of improving my skills, I designed my own application interface. Now it left to learn some coding.
