Good, but with Problems.

OS: iOS 12
Model: iPhone 6s

I’ve been using this app for almost a year, if not, more. I love the swipe to text feature a lot, but when I swipe out obvious words, it is a whole entire different word. I’ve also had a lot of bugs with the keyboard itself glitching out and changing to the default Apple keyboard mid-sentence. I love the app don’t get me wrong, but I have a lot of problems with it. I’m even typing with the Apple keyboard to avoid any problems on this review. I also dislike the fact that we have to purchase a keyboard that we like just to be able to use it. I get that you’re trying to get money, but we get a few keyboards that I’d actually consider cool. If we could get a couple more, I’d appreciate it a lot, especially the animated ones. All in all, it’s a cool app, especially for those who like the “Swipe to Text” feature, like me, but it needs quite a bit of improvement and debugging. I hope this helps further development!

Used to love it...

I've been using this app for a few years now. It used to be great, but it's garbage now.
1. As of today, I can no longer use the swipe feature using the rainbow keyboard...without paying for the app or allowing it full access to my personal information.
2. As of a few months ago I can no longer access my emojis from the rainbow keyboard...without paying for the app or allowing it full access to my personal information. This is a normal feature the developers took away to try and make you pay!
3. As of today, I can no longer type full sentences without the rainbow keyboard switching itself back in use when I try to use my normal keyboard (I mean, if I can't swipe-to-text or use my emojis I might as well use the keyboard my phone came with, right?)...without getting a notification on the rainbow keyboard, when it pops back up, about paying for the app or allowing them full access.
4. There aren't many keyboards I like/have access to...without paying for the app...and of course you'll have to give them full access to your personal information to use it.
5. In order to use the features of the keyboard (which is the reason anyone downloads this app in the first place) you have to PAY FOR IT and ALLOW THEM FULL ACCESS TO YOUR PERSONAL INFORMATION!!!
6. Last, but certainly not least, the "Black" and "African" emojis they made are offensive to say the least.

Is no one else experiencing these issues or am I being targeted here?!

Real words don't need auto correct!

I really like it except for one MAJOR complaint. It auto-correct obvious words...often to gobblygook! I used weed in an email a few minutes ago. It changed it to wed. While wed is a often used word, so is weed. It should only change it if I put in something like 'wd.' THEN it can guess at what I was trying to say. Also, can it capitalism (see...I typed capitalize and it changed it to capitalism) the letter i when it is an individual word? I hate going back through and fixing your corrections (collections and connections came up twice. Finally just typed each letter of the word 'corrections' to get it on here. I am ready to switch to another app.
