Lekh Diagram empowers you to express your idea on iPad and iPhone simply by sketching shapes with your finger.

Lekh Diagram can be used to make diagrams, UI Wireframes, flow chart, organizational chart, business process diagram, venn diagram, mind maps and any kind of illustrations.

Lekh Diagram’s powerful and unique shape recognition engine can recognize various shapes and connections. Draw shapes and connections by dragging your finger on ipad and the Lekh Diagram will recognize drawing and will convert them magically into beautiful shapes.

In addition to basic shapes (which can be drawn by sketching), Lekh Diagram also provides a library of predefined shapes. Shapes from library can be easily added to canvas.

Once a shape is drawn, it can be modified and customized. Use standard pinch-zoom gesture to zoom shapes and standard rotate gesture to rotate shapes. The Lekh Diagram’s unique vertex handle will allows you to precisely move vertices and control points of shapes.

The Lekh Diagram can recognize drawing connections between shapes. Draw two shapes and connect then whatever way you want simply by drawing the connection.

For very highly customizable drawing, the Lekh Diagram supports bezier curves. It can recognize bezier curve drawing and it also allows you to move the control points precisely.

The Lekh Diagram can recognize drawing and erasing of arrow at the end of line, curve, and open polylines.

Images can be inserted into your drawing from from photo albums.

And finally you can export and share your drawing in various formats. You can either email or upload to Dropbox. The supported formats are jpg, png, pdf, svg and lekh.

There is a limitation of exporting diagram in free version. In App Purchase of export feature will enable exporting of diagrams.

Thank You

This helped me create exactly what I needed. It’s not hard to use, It works fine, it looks good. Does the job right.

Pretty decent


I would love to have a basic electrical symbol library. Like contacts, relays, switches etc. This could be another in app purchase :-)

Well worth it


I was trying to create a simplified flow chart for a complex project presentation tomorrow. It has great txt fitting and logical controls. My only suggestion would be to add a double finger tap to toggle between selecting, panning, and drawing. I'm used to using this feature in splash top to switch between tap mousing and drag mousing. Anyway, great app, surprisingly good!
