Customer Reviews

Great Art

I'm actually taking the time to write a review so that's a good indicator of how great this app is. I love the designs that the app developers come up with, like Lightning Bolts, Dark Knight, and Spider-Tech. People always compliment my keyboard when they see it. There really is a keyboard for everyone with so many different styles, colors, and customization to choose from. Sometimes if I type too fast the keyboard glitches unlike the default keyboard on my phone, but that's my only critique, other than that this is a wonderful app!


This app is great and really east to use. I like the effects and how it really works!! I really recommend this app for anyone who wants nice keyboard themes. I really like how it functions, although you do have to pay for some effects, it works really well, and I actually prefer this keyboard over the iPhone keyboard, and I hope everyone who uses it agrees. I love the theme I'm currently using, and I hope this app get more more downloads and supporters in the future. LOVE THE APP!! <3

Changing my review

This is my original review and basically still stands: "Right on the front keyboard! Now that's what I'm talking about. I just dled this and will play around to see what else it has but not have to switch back and forth in simple, everyday writing is great. Just found an issue though. You have to manually move the writing space because it doesn't automatically do it itself."

However, at first I had access to the GIFs. But now I have to give you guys full access to every keystroke I have ever done or ever will do? Why?
