I recently made a neat thing! You can use https://ultimateframedata.com to check frame data for every character in Super Smash Bros. Ultimate! And guess what? It’s extremely mobile-friendly!
I was tired of there not being a single source for all of the available data, and I was even more tired of dealing with non-mobile-friendly sites and spreadsheets. I wanted something that I could easily check during tournament or while commentating, so I made this! And now, thanks to me spending a grueling four days parsing spreadsheets of data into HTML, you can use it too!
