Often artists need a grid for existing images to the proportions and perspective right. This small app does exactly that. A simple and free app for putting a grid on an existing photo. Grid size in terms of rows and columns can be set freely or based on presets. Line thickness can be set in pixels line color can be select from primary colors and line transparency can be configured. The image with the grid can be exported to a file or shared to other Android apps. Additionally you can switch to a comic like view of the image highlighting the edges and reducing the colors.


Features:

★ Configurable number of grid lines.
★ Arbitrary grid line thickness and opaqueness.

★ It does not need specific rights besides opening images and saving or sharing grids.
★ It exactly does what it is meant for.
★ Completely free & ad-free.
