Way better than flash cards!

I’ve really enjoyed using KeyFluent. The idea is simple but incredibly useful—it lets you naturally write messages while helping you learn another language at the same time. The translations are fast, and it’s a fun way to practice while having everyday conversations.

The app I didn’t know I was missing but needed!

Wow! What an innovative and useful tool to have.

Better keyboard with added bonus

I’ve really like this keyboard. Its interface is clean and adaptable. The swipe and predictive text features work great and help cut down on mistakes. Having the option to learn a language organically through something I use everyday is really nice to get a little practice throughout the day without having to set aside extra time. It’s a nice way to make everyday texting a little more useful.

Exactly what I’ve been searching for in a language app!

This is the only app I’ve found that allows passive learning when messaging. It’s phenomenal!
