Turn videos into your own notes. utudy is a note app you write in while a lecture video plays. Drop a timestamp as you write, and later tap that note to jump straight back to the exact moment it came from. ■ Just share the video link Share a supported lecture video link and pick utudy. The video arrives as a course. Share a playlist and every video comes in at once. No copying and pasting links. ■ Timestamped notes Tap the timestamp button while writing and the current playback position is saved into your note. When you review, tap the timestamp to jump right back to that part of the video. No more hunting for "where did they say that?" ■ A canvas you write on by hand Pen, highlighter and eraser. Lasso what you wrote to move it, then copy, paste, cut and duplicate to tidy up. Undo and redo whenever you need them. Drop text boxes, images, tables, shapes, sticky notes and stickers straight onto the page. ■ Pick a page background Plain, yellow grid, white grid, lined or dot grid - choose the background that suits how you write, and change it whenever you like. ■ Many pages in one note Run out of room and add another page. Reorder them, and delete the ones you no longer need. ■ Notebooks and folders Keep notes in notebooks, and notebooks in folders. Split them by subject, by source, by whatever makes sense to you. ■ Lock a notebook Notebooks you would rather keep to yourself can be locked, and unlocked with Face ID, Touch ID or your fingerprint. ■ Classrooms Create a classroom with the people you study with, post to it and share material. ■ Cloud backup Notes back up to iCloud, so a new iPhone or iPad picks up where the old one left off. ■ 24 languages Korean, English, Japanese, Chinese (Simplified and Traditional), Spanish, Portuguese, French, German, Hindi, Bengali, Tamil, Telugu, Marathi, Arabic, Turkish, Thai, Vietnamese, Indonesian, Malay, Tagalog, Burmese, Khmer and Mongolian. Lectures, tutorials, online classes - stop letting them wash over you. Keep them as notes. Contact mkideabox@gmail.com
