A checklist for when I’m leaving the house for the day to make sure I have everything
Paper checklists - I have to write out a new checklist every time and that really adds up as a time commitment, so being able to clear the checklist somehow is mandatory.
I use Notally a lot, but I think it lacks the clearing feature (if you mean to reset the whole list in one go). I’m not sure it even has the ability to duplicate checklists.
I might actually try out some of the other suggestions, they look really good.
