What's New in Caju

1.6.0

October 30, 2026

Grade by tapping the card. On the answer side, tap bottom left for Again, bottom right for Good, top left for Hard, or top right for Easy, and a soft glow confirms the grade. Connect Caju to Claude or Cursor with your own Caju sign-in, and manage connected apps in Settings. Forgot password now sends a Caju email with a link to set a new password. Moving between cards is smoother: no flash of the previous card or its audio, and your grade is saved even if the app closes right away. Undo now keeps flags and Study Options changes you made.

Brilliant for studying!

This app is already such a timesaver and amazing for memorizing! You can upload a file and the ai turns the data into flashcards!! Then, Caju tracks the time you spend studying and your success rate. Truly a must have for students or anyone trying to learn a new language.
