Black Highlighter is an app that makes it easy to hide secret information you don't want to share in images you're going to share anyway.

Hide people's names, e-mail addresses, embarrassing music choices, and more with just the swipe of a finger.

The Magic Highlighter

Black Highlighter includes a special feature, the Magic Highlighter. The Magic Highlighter detects any text you've highlighted, and adjusts the highlighted area to match.

The Magic Highlighter's abilities make it super simple to ensure you've made nice, even lines. It also ensures you've covered up everything you wanted to hide — no pesky descenders will sneak out.
