I started building Study Buddy, a simple Slack bot for students. I used the guide to set up the bot and added all the commands listed in there (e.g. ping, help, catfact, and joke). I then added a focus timer that lets students choose how long they want to study. Also I added a weather feature, but I decided to make it more useful by checking whether students may need an umbrella when leaving home and school instead of showing a general forecast.
