SigridDraw

Load your reference image from your photo library, then configure the drawing grid to your liking.
Reproduce the grid on any physical or digital media using the scaling module to help you get the dimensions and start drawing, cell by cell. The color picker allows you to retrieve the hexadecimal code of the selected color.
On iPad, use SigridDraw directly as a reference by displaying on the same screen your favorite drawing app (not included) thanks to SplitView.
Features:
• Fully configurable overlay grid (grid size, color)
• Black and white filter for the reference picture
• Pinch to zoom
• Color picker
• Scale calculator to compute your target grid size
• Split View support on iPad to display SigridDRaw and your favorite drawing app side by side
• Dark mode
