About this app

In Material Design, all components align to an baseline grid.

Keylines draws a grid overlay to measure layout sizes, margins and padding. The grid speeds up your dev process, and lets you analyze other apps too!

Broken on landscape. Key lines aren't placed across entire device (only a portion in the center) of the screen in landscape mode.

Why can't I set my own grid size? I used to be able to do that. Our design language uses 20dp keylines etc.

Hey Vlastimil, Keylines never used to let you set your own size, since it's built in accordance with the Material Design Guidelines that recommend 8dp. However, custom grid support is coming soon!

What's new

Fixed all of the issues with orientation, and the service persisting despite closing the app.
