I made some improvements to project, like remove authentication with email, now android devices don't have problem to use the website, and add enable/disable notifications toggle button on topbar.
Original Post: I created a web app that notifies you when you have new or closed sessions on Insignia. It has filters to filter the game list by name, serial or game save code, in addition to ordering by active users, active sessions, etc. It may contain some bugs, if anyone wants to help me find them, I would appreciate it.
