Choose from Calico, Black, or Robot, and enjoy 38 animations, including walking, jumping, and relaxing. Tap the cat to make it move out of your way. You can also turn it off in Settings. ■ Home Screen Widget Check the last note you opened right from your Home Screen. Tap the widget to open that note instantly. ■ More Features • Touch and hold paragraphs to move and reorder them • Insert tables, checklists, images, and hand-drawn sketches • Use the eraser to remove inserted items, including tables and images • Search all your notes with matching text highlighted • Lock individual notes with Face ID / Touch ID • Export and share notes as PDFs • Switch between Japanese and English • Adjust text size, fonts, ruled lines, and eraser width ■ No Ads, No In-App Purchases, No Account Required The app does not collect your data.
