【KEY FEATURES】 ■ Blanks that don't give away answer length ■ Every hidden answer is replaced with a blank of the same length, regardless of how many characters it contains. You can't guess from the length of the underline, so you can check whether you truly remember the answer. ■ Color-code with red and green pens ■ Simply drag over the text you want to remember to turn it into a blank. Use red for key terms and green for supporting details, or choose a system that works for you. Show or hide all answers of either color to focus on what you want to review. ■ Hints that help you recall, one character at a time ■ Can't remember an answer? Each tap reveals just one more character. Get a small nudge to help you recall it yourself, without revealing the whole answer at once. ■ Add images to bring your notes to life ■ Insert images into your notes. Keep diagrams, maps, and photos alongside your text to organize what you're learning. Note: Only text can be turned into blanks. Hiding parts of an image is not supported. ■ Two ways to test yourself ■ Choose & Practice: Pick the material you want to review, then answer paragraph-based questions in random order. Ideal for focusing on a particular topic. Target Weak Spots: Get questions selected automatically based on your test results. See the reason behind each selection, such as your accuracy or review timing. In either mode, you can open a question's source note from your results and save a quick memo about what you learned. ■ Pick up where you left off ■ Clopass saves your position in the last note you opened, along with which answers were visible. Even after closing the app, you can resume studying right where you stopped. ■ Study offline and keep your notes organized ■ Create and edit notes, study, and take tests offline. Duplicate, move, and reorder folders and notes to organize your material your way. ■ Share your notes ■ Send a share link to friends or study partners. You can also post links on social media to share your own notes with a wider audience. ■ Track your study habits and set reminders ■ See your daily study activity on a calendar. Choose the days and times you'd like reminders, and build a routine that fits your schedule. ■ Encrypted backups and data recovery ■ Enable automatic backups to encrypt your data and save it to the cloud when you're online. Use your recovery code to restore your data after switching devices or reinstalling the app. ■ No account required ■ No sign-up needed. Download Clopass and start learning right away.
