Everybody has tasks that have to be done again and again. Depending on the complexity of those tasks, creating checklists for them will help you save time and improve quality.
Checklists are used by surgeons and pilots on a daily basis to ensure that they dont miss out some important detail before performing an operation or taking of for a flight.
The tasks you perform might not put lives of others at risk, but imagine cutting 15 minutes from a complex task you have to do once a month because all information you have to check for that task is right there in a checklist.
The checklists you create will be shared to all of your devices via iCloud. You can also share the checklists with your co-workers or family via email!
