I have experience with Microsoft Excel. The first one I made a while ago is comparing the surface area and volume of balls of different sizes. I wanted to see how much faster the volume increased compared to the surface area.

This is my games list. I made columns that I can sort. If I wanted to see the games I beat, I can hide the rest of the games. On the side I have a table counting the number of games I beat, dropped, total, and hours spent. It updates when I make a change or add a new game. I also have the tables for each platform showing on a single worksheet tab to see all of them at once.

I have this app that tracks goals and one of the things I use it for is keeping track of how many times I’ve gone for a run. I run 1.5 or 2.3 miles when I run. The app has an export feature so I got the data converted to a usable form and made charts and counted the runs.
