Android screenshot editor

Edit screenshots the moment you take them.

MarkArea detects new screenshots in the background, shows a simple edit notification, and opens straight into a canvas where annotations stay adjustable until you save.

Why it is different

Start fast from a screenshot, then adjust every annotation as you work.

Automatic screenshot detection

Take a screenshot and MarkArea detects it in the background, then posts a local notification so you can start editing without opening your gallery first.

Tap notification to edit

Tap the notification to open the new screenshot directly in the editor. Screenshot-editing tasks such as work notes, feedback, tutorials, and everyday sharing all move faster.

Re-edit annotation objects

Text, brush strokes, arrows, lines, shapes, mosaic, and imported images remain selectable and adjustable before saving, so one mistake does not force you to start over.

More than basic markup

Add text, draw with brush tools, hide sensitive content with mosaic, import extra images, create a blank canvas, and prepare clean screenshots for sharing.

Built for candlestick charts and applying Adam Theory

Use lines, parallel channels, visual comparisons, and selected-area copies to annotate candlestick charts (K-bars) and apply Adam Theory.

All image processing happens on your device

Your screenshots, imported images, and edited results stay on your Android device. MarkArea performs all image processing on-device and does not upload images to the cloud.

Editing highlights

Start from the screenshot notification.

MarkArea watches for new screenshots and gives you a simple local notification, so the newest capture opens directly in the editor instead of getting buried in your gallery.

Move, resize, and revise objects later.

Brush marks, shapes, arrows, and other annotation objects remain selectable while you work, making it easier to adjust a note instead of starting the screenshot over.

Draw clean lines for screenshots that need precision.

Line and channel tools are built for screenshots where direction, comparison, or chart markup needs to stay readable after sharing.

Copy part of a screenshot, then flip it.

Select an area of the screenshot, copy it as an independent object, then flip it horizontally or vertically to apply Adam Theory techniques.

Edit text as part of the canvas.

Add styled text, choose a font, and keep text editable while preparing labels, instructions, or visual notes for a screenshot.

Create a blank canvas when there is no screenshot.

MarkArea also works as a quick local canvas, with custom colors for sketching, explaining, or composing visual notes from scratch.
