Simple Keyboard gives you, yes, a simple keyboard, with support for tap-based typing — and that’s pretty much it. There’s no text correction system, no next-word prediction, and no support for swipe-oriented input. There’s not even access to any sort of voice-to-text system, which every other app in this list provides. Heck, aside from a humble set of simple options, Simple Keyboard has no bells and whistles whatsoever. It is, quite simply, a keyboard. And that’s all it aspires to be.

The aptly named Simple Keyboard has a limited range of options — which in and of itself is essentially the app’s defining feature.

So why would you want such a frills-free typing experience when so many rich, feature-laden alternatives exist? Well, you might not want any of those added elements, for one, and might be content to have something that just lets you tap in words as needed. But perhaps more prominently, Simple Keyboard’s lack of lofty ambitions gives it one powerful feature no other keyboard can match: privacy — built in at its core, with a ground-level assurance that nothing you type could ever be transmitted off your device by the keyboard itself.
Pretty much every other Android keyboard app, y’see, requires perpetual network access in order to operate. And while most of the major players say they’ll never do anything nefarious with your data, there’s no denying that they do at the very least have the ability to observe and transmit it. (The need for internet access can be explained in a variety of perfectly legitimate ways, including the ambitious options those apps have for performing internet searches and even just learning your typing habits over time in order to provide better predictions — but still, if maximum privacy is a top concern of yours, that may not be enough to make it acceptable.)
