Unless you’re somebody who’s been blessed with eidetic memory, even the best of us could use some help from time to time remembering snippets of information. This is where Purrfect Memory ($3) by Top Storey comes into play. This handy little app sits up in your Mac’s menu bar, prompting you to fill in the blanks on any phrase, list, or other set of words you want to remember, adding more and more blanks with each iteration until you’re ready to fill in the whole phrase or list by memory.
