Annotate is screenshot markup that respects your time. The obvious tools are there (arrows, text, shapes, shadows), but the details set it apart: curved arrows you draw by dragging the middle, blur, pixelate and loupe for redacting and highlighting, snap-to-everything alignment guides, real layers you can reorder, and one-tap backdrops. iPad-first with Apple Pencil, just as nice on iPhone. 5 free annotated images, then a one-time unlock. No subscription.
