Mr Madras ,

4 star because....

I have given this app a 4 star as it is a fun and creative way to customise you keyboard. It is also a great way to make typing easier for it auto corrects and you can change it to fit you also can make the keys a brighter colour so you can see the keys easier👍. Both me and my family love this app and highly suggest it though it has one lower point You have to pay for the nice keyboards have fun and be creative

GO WILD!!!!!

Amazing but BEWARE

This app is amazing and its really good for kids because kids should be able to be creative and customise there own keyboards they designed them selfs, but, there are problems with this, like any app! This app is collecting data, so anything you type on this keyboard will be accessed by rainbow key. So to stop this dont allow full access. I know it ruins the fun of it all, and you cant do all the things you would like to but, its very dangerous. Kids are playing on this app, it then asks them to allow full access, obviously you just press allow full access on, then you start having loads of fun with your new customised keyboard and basically use it for everything because its new, exciting, right! These kids have NO idea that everything they use their keyboard on is being accessed and seen by rainbow key! But do they realise? No, no they dont. This is why i do NOT recommend to allow full access, (this is not suggesting you have to delte this app and fear it I’m just trying to say to not allow full access) Thank you for reading, please take this advice on board.

Its pretty cool...

Rainbow key is awesome!!! The only annoying thing is that whenever you go on to the app there is a advert which is made by rainbow key and it ALWAYS comes up!!! So annoying! Other than that its so cool and I would advise getting it especially if your creative! 🦄🦄🦄 the other annoying thing is it always makes you sometimes have to buy a keyboard!!!! If rainbow key are reading this have a few nice ones that you don't have to buy!!!!!!!!!!!
