KOHow it works
Set your languages
Tell Alterengo what you speak and what you are learning, and how much immersion you want to start with.
Live your life in it
Write notes, plan with the assistant, do your day. The interface teaches as you use it — a label here, a button there, always within reach of what you know.
Look anything up
Tap any word for its meaning at your level. Every lookup is a little deposit; the app keeps score of what you have met and grows with you.
Organized, focused, and growing — in every language you live.
Free while in alpha. Open the app and let your workspace start speaking your languages.
