The app is awesome! I purchased the full version, and I definitely donβt regret paying for the lifetime access. It would be great if you could make the input more integrated into the keyboard, like Gboard or any other keyboard. Also, I hope you can make the input buttons wider on the keyboard because even when I make it tall, the keys still feel small and narrow.

The app needs to manage its hight problem plus suggested words should be on top and shortcut tools should be down to the suggestions and the key blocks should be continent size to write easier and one more thing its word learning speed is slow suggested words are not compatible according to desire

This is an excellent application that stands out due to its impressive keyboard features, which offer a wide range of multifunctional capabilities. Among these features is an advanced AI paraphrasing tool that operates similarly to Grammarly, enabling users to easily rephrase and enhance their writing for clarity and effectiveness. Additionally, the app includes an extended clipboard functionality, allowing for more efficient copying and pasting of text, which further enhances the experience.

This app has locked my phone it's been 14 hours it can not pop up so that I unlock my screen. This put me in danger coz i coud not pay or use my phone am I regretting not to install it in my phone. I try now to sign in using another phone so that I can uninstall it from locked phone but it doesn't give me the option. Am just regretting and I do not advise anyone to use it since I was almost detained for not being able to pay.

The aggressive pricing coupled with the many fake reviewers praising the paid version just goes to show that the company's business model has shifted. I've had fleksy on my Samsung for a while and always appreciated the simplicity and robust engine behind it. Now can endorse a product that is trying to jump on the AI wagon all while passing on the cost to the average consumer. Developers if you're reading this: ain't nobody paying no $80 for a keyboard app. Signed, everyone

You need to fix the return of the default prompts because I don't know what trigger, but the AI returns the results with single quotes throughout the text. As a consequence, if the text already has double quotes, it is reduced to single quotes. This happens in all correction prompts and in the translation prompt.
