### 5/5 — Amazing Tool

*2026-07-02, version 3.5.2*

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.

### 5/5 — Everything you need

*2026-06-10, version 3.5.1*

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

### 5/5 — Simplicty at its finest

*2025-12-29, version 3.5.1*

It doesn’t require an engineering or math degree to figure out how to use this- which is perfect for me because I wanted to create home network and various diagrams and now can do that easily.  It would be nice if they had a few more icons- but otherwise a great find!  Love the syncing.

### 1/5 — This app is terrible

*2024-03-07, version 3.4.7*

The UI for the app is awful. It's borderline unusable. you can;'t even adjust the size of text boxes efficiently. Text disapears, and reappears, you can't see half of the stuff you've typed. Don't bother downloading.

### 2/5 — Can't recommend because of notifications

*2023-12-11, version 3.4.1*

It is a great app, very intuitive and easy to use. It has a great UI and I really wish I could keep using it. But the notifications make it unbearable. All I want is an app that allows me to design some things offline and this app does that. HOWEVER, everytime you open or one of your diagrams, it will prompt you over and over that you can only create 5 diagrams offline and you need to upgrade to the online edition to get around this. Everytime I open the app or a diagram, I have to clear 5 notifications stacked on top of each other just to use it. I appreciate the notification, but could please make it so once the user dismisses it, it stays gone!!! I would love to use this app again in the future!

### 3/5 — Not the best choice

*2023-11-12, version 3.3.4*

Doesn’t support Split View on iPad, not sure if importing documents is an option but I haven’t been able to find an option for that, app can get laggy especially when erasing, too many pop ups, Quality of image importing is very poor.

Also if you’re looking for a free to use app, beware that all your whiteboard will be on view only after a few weeks after the free trial ends. 

The unlimited space and file sorting system is nice.

### 5/5 — Useful tools for mind map

*2023-09-18, version 3.2.5*

Design Ingenuity，Simple and beautiful

### 4/5 — Really nice, but could use some enhancements

*2022-10-16, version 3.1.0*

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?

### 5/5 — Great app

*2022-01-28, version 2.3.6*

Simple but great app.

### 5/5 — Excellent for my home network.

*2022-01-12, version 2.3.6*

I was looking for an app to help me map out my small home network (about 35 hosts) and so didn't want something with a subscription as I'm only going to update things very infrequently.

I was blown away by how well this app works. 

After a quick scan of the help page, I quickly drew a map of my network. Everything works logically. I did not experience any bugs or glitches. Everything just worked.
