Lekh: whiteboard & diagramming

Fantastic for designers. Can make professional sketches with the smart snap tool, and make fine adjustments to anything you’ve drawn. If is doesn’t already have a shape in the library, you can draw and save your own versions, fantastic for niche applications. The export engine is powerful, allowing you export however you need. I’ve used this to create professional sketches for patent designs, tactical images and everything in between.

Extremely easy to use and very good design. Arrows are easy to align, easy to create boxes and move them around, really the only app I have found that you can create good flowcharts on

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