Check Em All is a very simple and no-nonsense application that is definitely going to be useful if you happen to have many numbered checklists to manage. Instead of messing around with Memos, or creating dozens of tasks, or purchasing an application that still doesn't have the numbers pre-entered, you could easily manage your works with preset numbers up to 100 for multiple databases. For example, you need to revise Chemistry before your term exam, and you have around 20 lessons. You choose to revise them in a random order. With Check Em All! you can enter the total number of lessons in the uppermost field, and then you can check next to the lesson numbers you've finished revising without the hassle of searching for scraps of paper or folding the book's edges as signs. So this is 2-in-1; you remind yourself of the total number of items and the certain numbers of items done. Another example; you decided to watch a bunch of Family Guy episodes on several DVDs. You can check next to the corresponding numbers so that you don't forget which episodes you've already watched. The choices are endless...
