Ticket, issue, task, card, story...What's the difference?

In the Board Genius app, we try to stay consistent and use the word "ticket". However, each platform has their own nomenclature. If you see us use the word "ticket", this probably also refers to:

• In Jira: a story, epic, bug or task,
• In Trello: a card
• In Github: a issue or pull request
• In Gitlab: a issue 
• In Asana: a task
