Really nice, but could use some enhancements

I really like this. I’ve been looking for an app to easily create and edit schematics for off-grid solar and battery installations. I’ve been using “Graphic” which has a lot of really great features, but it doesn’t allow for dynamic connections between elements which is where Lekh really shines for me. I’d really love to see some improvements to the UI though: • Keyboard shortcut support, for undo, redo, delete, cut, copy, paste, arrow nudging of elements etc. • Better non-keyboard support of cut, copy, paste, undo redo etc. • An option to have the connection lines go all the way up to the elements they’re connecting, instead of leaving a small gap. • Option to have lines automatically make a little curved bridge when the cross would be amazing to show that the lines are crossing rather than touching (important for electrical diagram). • A way to merge items into one. Could be a layer system, or a menu command to join elements together. • A way to paste graphcis from the system clipboard, rather than having to import from photos each time. • Ability to label/annotate pasted photos/graphics in the same way that you can with the normal shapes. - the way that the “Graphic” app deals with this is really nice. / / / Overall I really like this and it does what I want, but it’s a bit clunky especially without the keyboard support. I’d be happy to pay a reasonable one off fee for this, and every now and then for major updates too. I would not be happy if you adopt a subscription model. 😕 I’d love to hear back from developers with your thoughts?

Great until started crashing.

Nice program, got paid version. Soon started crashing. Lost saved diagrams, hours of work. Not trustable. Otherwise would be a great app.

Wow. This is an amazing find

This is an extremely well thought out App, the UI is very very good. Hats off to the developer, I paid for the Pro immediately
Just hope the app keeps getting developed, its got a lot of potential to get even better.
It’s got so many nice touches, as I explore more I will come back and edit the review
EDIT:
As you add a line next to an edge of the paper background it just automatically expands, amazing.

Some Issues

I use this mainly to create wireframes for documentation. While on the whole it is a good application there are some annoying issues were the text gets messed up on the page. There does not seem to be any fix apart from restarting the application - I don’t seem to loose anything thankfully. So far this has worked well enough with the IPad Magic Keyboard to become a fixture in my workflow replacing an older application. Being able to arrange the pages into a directory structure would be helpful, or integration to iOS files.

Easy to use for quick diagramming

Nice simple app to organise your thoughts. I also thought the help was clear and useful, and within few minutes I was using it to solve my problem. Sometimes it is not as smooth as it should be but I am sure that can be improved.

Needs more instructions

This is a cool app. It's a shame there's no "help" option though. Btw to add text double tap the screen. Couldn't figure out how to add colour or textures unfortunately.

Excellent performance, and Great value

Updated Review:
Having experimented a little more, I have to mention that the text handling appears rather flakey: It is possible to re-size, and edit the content of, existing 'text in a box', but it does not appear possible to change its colour. .. 'floating text' however, can be re-coloured [!]
I am keeping with my 5* review, because the App has such great potential; but would request that the Authors improve the text-handling as a matter of some urgency.

Original Review:
For those like me, who once used expensive templates and Rotring pens to draw charts and diagrams; this App is a revelation.
Yes, it's been possible to do this on computer for decades now ... But this is an iPad App, and works beautifully !!
Those that whine about the price should really stop and think for a moment: It's free to try and cheap to buy.
.
On brief acquaintance; I have only one feature request ... please add the facility to change the paper size.

Does a good job

Like this very much. Relatively intuitive.
I needed to draw a simple wiring diagram and I was build some custom shapes
Just missing a couple of minor features - hence 4 stars
1. Ability to copy custom shapes (group) between drawings - or save them in the library.
2. Further share option to email with Gmail.
I hope these things will follow.

Incredible

Such a good app. It has made taking notes in lectures so so much easier. I do engineering, so there are often a lot of diagrams. In fact, the diagrams were the one thing which stopped me from completely digitising my notes, but now it might be possible. I use notability for note taking and from now on I shall be using Lekh Diagram for my flow charts and diagrams. Keep up the great work, developers. Maybe add in some support for graph sketching and features such as auto joining lines and auto aligning centre of shapes

Love this app but......

I keep trying to give them my mobile for exporting and it will not take it! Without export it is pretty pointless for me!

Great until ios7

Worked brilliantly until I upgraded to iOS 7. Now when I try to draw I just scroll instead.

Brilliant

So good I have written my first review! Easy and intuitive to use. Auto-shape function speeds drawing and is very satisfying. Great product.

A brilliantly simple way to draw diagrams

Shape recognition saves tiresome searching through lists of standard shapes. Simplicity is the key to its ease of use. Yes you do need to buy the export facility but you get to try out its features first, then you can choose whether you want to pay for it.
Looking forward to future updates. Would like a bit more control over vertices, eg convert to curves or add points to lines. Also a group/join shapes feature.
Worth the money.

Cannot print or export

This app admits export limitations - which is stretching the truth!
Having built my flow chart I could not do anything with it.
On principle, I expect honesty from app developers - don't advertise an app as free when in effect it is not.
So app deleted... I expect I will end up paying more for an app where I don't feel misled.

Brilliant - works as advertised

I'm a big fan of instaviz (and graphviz) but this app has a place right next to it on my iPad.
