Apps about everything. Apps for everything. Apps everywhere. There are now well over a million apps in the app stores for iOS, Android, and Windows devices combined. And if, like me, your working day and private life involve using mobile devices, then you’ll know that sometimes it can seem like there are too many apps. How, among this cornucopia of code, do we find new, great, or cheap ones? (Apart from this column, of course.) Each app store has curation, with sections for editor’s picks and top-selling lists and so on. But there are also apps for this task.
