Review summary

Reviewers praise Lekh for being easy to learn with an intuitive UI and strong shape recognition that turns rough sketches into neat diagrams. It’s highly regarded for quickly creating diagrams (network diagrams, flowcharts, UML) on iPad and syncing across devices. The main downsides are a paywall for exporting diagrams and a limited icon library, with occasional notes on zooming/placement limitations. Overall, a powerful, user-friendly diagramming tool hampered mainly by feature/paywall restrictions.

Pros

Intuitive and easy-to-use UI with a clean, simple design.
Excellent shape recognition that cleans up hand-drawn sketches into neat diagrams.
Great for quickly creating diagrams like network diagrams, flowcharts, and UML on the iPad.
Reliable syncing across devices.
Strong vector drawing capabilities that produce tidy diagrams with minimal fiddling.

Cons

Exporting diagrams typically requires an in-app purchase or upgrade; free export is limited or not available.
Icon/symbol library is limited; users want more icons or the ability to add custom objects.

2026-07-02	Mi*****	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.

2025-12-29	Bo*****	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.

2023-12-11	Re*****	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!

2019-03-21	ap*****	Draw a rectangle in two strokes? You get a straight line a d a curve , making a P shape. Draw circle with the tiniest bit of overlap, no circle recognition for you. You get a peach. Tedious.
