How do I anonymise a picture?

You can blur faces, special tattoos and names or birth dates with tools within the app. After opening or snapping an image, you can select the ​‘Edit’ icon. With the blur tool, you can obscure parts of an image, and with the arrow tool, you can place a red arrow to indicate something important in the photo. Don’t worry about messing up. There’s an ​‘Undo’ function to clean up the mess — if only that existed irl!
