During the COVID era when I was in college, friends who couldn't meet their classmates in person wanted connection, and the concept of "Zoom study" was created and became popular. Zoom study is a virtual study room where people connect to a video conference call, mute their microphones, and share the scene of them studying.

The college project team I created called Higher Definition was running Zoom study sessions and wanted a way for acquaintances who came to Zoom study to interact. So the operator would ask visitors what they studied that day, record it, and post it on the Instagram account. However, the friend who was in charge of this work got tired of creating and uploading images every day.

So I created a simple web app using php, mysql, and html that I learned in my IoT class at school, and users enjoyed it during the month that Zoom study was operated.
