Ratings and reviews

😊 Hi there! I've been having a bit of trouble with the CharacterKey AI keyboard app—it keeps stopping on me. It’s a little frustrating because it disrupts my workflow. I really see the potential in the app, and I’d love to use its features more effectively. If you could provide a solution soon, that would be amazing, as I depend on this tool for my daily tasks and communication. Thank you! 🙏

This keyboard application is great but.. there are worse and missing, things setting for managing the keyboard size and the theme, keyword size & more.. and option to hide the tools.. anyways it will be fire if u just use ads on premium stuff. because not all people are gonna pay just for a special keyboard feature.

sorry but this app isn't for me when you go to settings and click on charakey to allow it on my phone gave me a warning that it might take my data of everything on my phone including data of credit cards and it'll even ask if you want to proceed with a reboot plus 99% of the stuff on charakey you have to pay for it waited a long time for this app to come out but seeing it now and what it can do to my phone and all my data I just can't trust it a single bit
