Problem Solving Tracker
I have created a very simple website where you can track how many problems you have solved in a particular time.
You can also see the time needed for solving each problem. To use it, start the timer when you begin coding. When you solve a problem, just click the 'increase' button, and it will display when you solved that problem and how much time you needed. You can also include the problem name when clicking the 'increase' button, although it is optional.
This website does not store data on the server side (I am not a professional), so reloading the page will erase all data. I will update this site continuously. I hope you find this site helpful—it's just a small approach. I would deeply appreciate any suggestions you can provide.
