Your notes live on the Lock Screen. You see them every time you pick up your phone — nothing to unlock, no app to open, nothing to forget. You wrote it down and never looked at it again. LockNotes fixes that by putting the note where your eyes already go. ■ Tick off tasks without unlocking Today's to-do list, the groceries, the thing you keep forgetting. Tap it right on the Lock Screen and it's done — the widget updates instantly. ■ Boards and lists for the bigger stuff A trip, a move, a school project. Make a board, add lists and cards, and pin the one that matters to your Lock Screen. Use it as a planner, or as a simple checklist. ■ 150 papers to pick from Paper color, ink color, grid or lines or dots. Pinch through 150 designs until one sits right on top of your wallpaper. ■ Handwrite, draw, doodle Seven pens — pencil, crayon, marker, fountain, watercolor and more. Scribble the way you would on a real sticky note. Drop in doodles and photos from your library as stickers. ■ 34 fonts Handwritten faces that read like a real notebook, and clean ones for when you want it tidy. Latin, Japanese, Korean and more. ■ Write together, live Share a note or a board with a friend using one code. You both write on the same paper and you both watch it change — live, on both Lock Screens. ■ A nudge, if you want one Set a daily reminder and pick the time. Or don't — the note sits there patiently either way. ■ Yours by default Notes stay on your device. Only what you choose to share goes to the cloud, only after you agree, and ending a share deletes it. Also inside: a Home Screen widget, a Live Activity, a diary of everything you have written, and 50+ hand-drawn app icons to match your mood.
