Lekh Diagram

By Rajeev Kumar

Open iTunes to buy and download apps.


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, 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.

Customer Reviews

I'm going to try and be kind

This is not a good app. It does not draw lines the way you want, you cannot place objects for text where you want. I used a stylus and still couldn't make it work. It randomly changes size and scale if you breathe wrong. You have to pay $2.99 for the privilege if exporting it. But after 3 hours if fiddling around trying to create something, I have ZERO to show for my effort. I should have just burned 3 $1.00 bills.

Not worth

It can draw (not well) and it does shapes (not well) and you have to pay to export flowcharts. Handy if you need to make a quick one on the fly, otherwise there are much better options.
