This should never be used on your phone. I would write a whole presentation on why, but by slide 3 I would've thrown my phone across the room in rage due to how buggy the app is. Some glitches you can get a hold of and work around, but not this one. It's entirely random if it just combines some words, puts your cursor back a few words whilst you're typing, or just freezes up. All of this happens multiple times a minute. It is mildly infuriating, but it can be a little bit funny.
