There use to be a good swype type keyboard for iPhone called shapewriter. But they were bought out and removed from the App Store. Since then there have been many very bad attempts.
Every single one I've tried from the App Store are terrible. So when I finally found one that actually works. I had to come here and make a guide for it.
All the others currently in the App Store actually slow down your typing speed because you have to spend so much time correcting the words. But path input is surprisingly accurate.
I know you probably wish we could use this as our native keyboard. I do too. But apple doesn't allow this. So this is the best alternative I've found without jailbreaking.
Well there you have it. When I find something good I like to pass it along. I hope you find it useful.
