I love Rainbow key you can make keyboards and get fancy fonts to type with my only complaint is that it doesn't let you access some keyboards and stickers because it says you need the full version well it would be nice if they let me access the clown fish theme!!! Anyway I don't recommend this unless you don't mind spending $10 a month for keyboard fonts. One more thing is they don't let you access some keyboard backgrounds and all other materials to make your own keyboard themes they also only let you make 2 themes, unless you pay $10 a month😑 I still don't understand why you have to pay for keyboard fonts and themes?!!

٩(♡ε♡ )۶ still love it (^з^)-☆

ι ℓσνє тнιѕ кєувσαя∂ αρρ αи∂ αℓℓ ιтѕ ρєякѕ! I know you have to pay if you want more content from the app but at the moment I am just fine with the keyboard content I have and can make. Except for the fact that you can't watch a few adds for a couple of extra content for making the keyboards you want and etc like I was able to a while back. Now all of the premium content is permanently locked to people without premium so if I only wanted to use one extra thing for making the keyboard for an ad I am now unable to. Other than that, I still think this app is pretty great and has several good choices to use for free and your still able to make a keyboard (but only limited to a few choices for the buttons etc). Even though it has most of the stuff locked for premium it still has some good content I am able to use for free and to me it is basically the best custom keyboard app out there on the app store. ٩(♡ε♡ )۶ -ps I really love the emotes!

I've had this app for a few years now, and it's pretty solid. So many times I've had a friend over my shoulder while on my phone. They never fail to take notice of my keyboard. "Ooo, how'd you get that?"
Rainbow Key, of course.
Comes with most aspects of a regular phone's keyboard... maybe even a few more features than normal...? I've used Rainbow Key for too long to remember.
I only ever complained that the emojis were in short supply, compared to the original iPhone keyboard's updates. But even then they managed to input a few additional emojis from the original (updated) keyboard (even if it wasn't as many as I'd like).
I'm giving Rainbow Key 5 stars because not only is it a pretty useful and impressive app, but their continuous modifications (like the emojis) show that they listen to their users.
