For now I'm using TouchPal because it has auto correct and a nice amount of themes. 2 things that are important to me. What are you using and why?
My eyes are bad, and I have problems with the light coloring of the stock predictive words. SwiftKey is black and I see the words better.None, because none of them are any actual improvements that I can tell. At least, not on an iPhone 5. And some of them are definitely worse with predictive text that cannot be turned off.
For me to like auto correct, I would need to wipe it clean and start over. Too many mistakes I have made keep coming up as options. Many are not even words.One thing I will say. As much as people complain about apples autocorrect, it's much better than a lot of these keyboards. I like swiftkey but it was TOO aggressive and messes up tags on social media.
