ColorNote Notepad Notes (free). The only thing overdone in this app is its repetitively redundant name. Much more importantly, it’s a great barebones listmaker, providing a sheaf of virtual paper on which to capture reminders, to do lists, and random ideas. You can create two kinds of lists: checklists and plain notes. The first come with a gratifying feature: Swipe any item and it gets crossed off. Plain notes look like a big yellow pad stuffed onto your Fire. A built-in sharing tool makes it simple to append any list to an outgoing email.
