My method of packing my bag is to first write down the things, I need for my journey/stay. I keep updating that list and then on weekends I put those things and do a tick mark. I want to know that is there any app, where I can keep putting the items I need to keep. Once I am putting those items, I need to keep marking it as done. However, I should be able to uncheck also, when I have removed that item. Please suggest me some app for it.
