OpenBoard

OpenBoard is a free and customizable open-source keyboard app based on AOSP, whose strong point seems to be the level of security and respect for privacy it offers.

OpenBoard is a keyboard that will quickly adapt to its users' needs. You can configure different parameters depending on how you use your smartphone keyboard: split the keyboard in two, enable dictation mode, and so on. In the OpenBoard settings, you can radically change the style of your keyboard by choosing between different colors and types of fonts. In addition to this, one of the most exciting features of the keyboard is that its color will automatically adapt to whichever app is currently in use.

Another useful feature that OpenBoard offers is advanced word prediction. With this tool, your keyboard can recognize its users' most used sentences, predicting what they are going to say without them having to type it. To use this feature, all you need to do is tap on one of the predicted words in the upper part of the keyboard. The keyboard does not include emojis.

OpenBoard is an alternative to the default keyboard apps installed on your devices. However, although it offers many different features, these don't include everything that is usually covered by default keyboards.
