Update 4/10/2022:
Thank you all for using my bot. I didn't realize it would grow to where it is now. I'm extremely happy about its popularity. Unfortunately my database is poorly designed. I need to redo some things but I'm currently studying abroad in Korea and don't have a lot of time. When I come back, it'll be better than ever. Please leave more suggestions down below :D

Calcifer is a study bot currently used by 1000+ people and was originally for a productivity twitch streamer's discord server. Users have the ability to start pomodoro study timers from 10 to 120 minutes as well as set break timers.

Unlike other study bots, Calcifer also has a database that tracks how long users are studying. Users can query Calcifer for their productivity stats and Calcifer will tell them how many minutes they've studied while using the bot. Calcifer can also tell users the Top 10 users in the server who use the bot. 

Calcifer also supports group study/work sessions. Users can study as a group and their timers will be synced as one. In this mode, Calcifer will join a discord voice channel and notify users when their timers are done.
