Sankey Flow Designer - diagram

Create Sankey diagrams with custom flows, values, colors and SVG.

Create clear and customizable Sankey diagrams directly on your Android device.

Sankey Flow Designer helps you visualize how money, energy, materials, resources, users, or other values move between sources, processes, and targets. Build simple flow diagrams or detailed multi-stage structures with an intuitive visual editor.

Create diagrams step by step
Start with a source and expand your diagram by adding targets and branches. Continue flows across multiple stages and display proportions through flow widths.

Edit directly
Change node and flow names, values, and colors. Add branches directly from a node while keeping the diagram visible. Zoom and move around the canvas when working with larger projects.

Automatic layout and checks
Optimize node positions and spacing to keep complex diagrams readable. Optional warnings identify exceeded source values, incomplete distributions, unconnected nodes, and zero-value flows without blocking your work.

Customize your diagram
• Set individual colors for nodes, flows, text, and the background
• Use source or target colors for connections
• Adjust node width, spacing, flow opacity, and text style
• Display values, percentages, currencies, units, or custom labels
• Choose horizontal or vertical flow direction
• Use a light or dark interface

Export in high quality
Save diagrams as high-resolution PNG images with a background or as transparent PNG files. Export scalable SVG vector graphics for documents, presentations, and design software.

Save and restore projects
Projects are saved automatically while you work. Create complete project backup files to transfer diagrams to another device or restore them later.

Use Sankey Flow Designer for budgets, energy analysis, material flows, process visualization, resource planning, user journeys, and other flow-based diagrams.
