Ratings and reviews

I had a one-off requirement, a diagram I had sketched on an index card a while back. Decided quick look and see what's on the play store. Found Lekh, installed. Had my diagram completed and exported to my phone in 10 minutes. Lekh is very intuitive and recognized shapes, resized instantly. Easy to add text at desired font size etc. I don't have an ongoing need for Lekh cloud. Just want the dev to know this is a cool app.

Veryyyy useful, doesn't have watermarks, has lots of features, love it. In the mobile app I didn't know how to insert text in a diagram at first, so had to try a lot of things. Then I found out that you just have to double tap on the diagram. Edit : There are only 4 font Styles available for text, it would be wonderful if there were few more.

Extremely useful app for me. I produce a lot of diagrams for work and more generally my brain works in pictures. I have been hoping for an app like this since I bought my first smartphone. There are some things I hope they improve but this is the only diagramming app available that can really be used on a phone. (DrawExpress is brilliant too but it is more specialized.)
