## What is MarkSnap?

Make screenshots easier to explain with MarkSnap. Detect shapes on your device, highlight the right area, and add arrows, nearby text and numbered callouts for clearer feedback and instructions.

FIND A SHAPE, THEN MARK IT UP
Import a screenshot or image from Photos, or paste one from your clipboard. Run Standard or Detailed shape detection, then tap a detected region to turn it into an editable annotation. Recognition runs on your device; your image is not sent to a remote recognition service.

ADD CONTEXT WITH +
Use a selected shape's + control to add an arrow, then add a note beside the arrow's + control. Text stays close to the point you want to explain. Delete a parent annotation to remove the annotations linked through its + controls; separately created text stays independent.

MAKE STEPS EASY TO FOLLOW
Add numbered callouts and change their fill color from the quick controls. Use arrows, rectangles, circles, ellipses and text to explain a bug, review a design or build a visual tutorial.

REFINE AND SHARE
Adjust positions, sizes, colors and line styles. Undo or redo edits, zoom in for detail, and preview your annotated image before saving to Photos or opening the share sheet. Choose light, dark or system appearance.

FREE USE AND PREMIUM
Free use includes export limits and a MarkSnap watermark. An optional Premium in-app purchase removes export limits and watermarks. See the app for current purchase details.
