Very customizable (I like having number row always visible, and having long press for symbols on each letter).
Has gif support built in.
My biggest pain point is:
It auto corrects words that are spelled correctly to other words. I type "our" and it changes to "out", I recently typed "purpose" and it changed it to "purple". Autocorrect is awesome and necessary, but I hate that it corrects words to other words and not just typos. I wish I could find a keyboard that has the things I like without this annoyance.
I use Fleksy, probably not as popular because it doesn't have swype typing but I find the autocorrect works really well, and it's easy to change the word if you don't like what it corrected to by swiping up or down to different options, and you can swipe left to delete words. Built in gif support too, and there's an extension to make the number row always show.
Nice! That sounds pretty great (I don't use swipe typing at all so no loss there). When you delete a word from correction, is it only deleting it in that exact situation (our to out), or is it deleting out from the dictionary entirely? Hoping it's the former and that might be exactly what I'm looking for if so.
Sorry, to clarify, swiping left is like backspace a word, if I swiped after now it'd delete "now", then "after" if I did it again. If you typed our and it changed to out, you could swipe up and it'd revert back to our.
You can add or remove words from the dictionary by opening the app separately too, but most settings are accessed from the keyboard.
