"Counter" is self-explanatory. It is a counting software that is simple to use and reasonably priced. It doesn't have too many features and focuses on simplicity and directness.

Home page functions:
1. In the upper right corner of the home page, click "Quick Add" to access a shortcut to quickly add a counting item. This is to make it easier to count, as you can add counts cleanly and quickly without having to create many styles first. Just click to create and start counting.

2. "Add" is the normal way to add a counting item. You can change the color of the item you create and use pre-made styles to quickly create items.

3. On the home page, swipe right on an item to reset or pin it.

4. On the home page, swipe left on an item to edit, delete, or archive it.
