Android: Ever since personal computers became a thing, handwriting has become less and less common. However, if you're still in love with the good, old-fashioned writing method, Google's new handwriting keyboard allows you to write words to input them as text.
The new keyboard gives you a large, open space to write words. It will read whole sentences at a time, so you don't have to slowly sketch out each individual character. It will work with your finger, but using a stylus will probably feel the most natural. The keyboard supports 82 languages and can read regular or cursive handwriting. Not bad.
