What Customers Say About Using Limnu

I work with people from Africa and Middle east, and found out, that Limnu is superb to use, when we communicate. A painting or a picture can tell more exactly, when I have to explain something for them, when they don't speak well danish.

Bjarne H. (Denmark)

I am a full-time online math tutor, and so far am impressed by your online whiteboards. The low resource usage and infinite space are two features which are really important to me. I need to be able to write quickly, and never run out of room!

Matt L

Limnu delivers a simple, smooth drawing experience. Drawing with a mouse in a browser feels remarkably fluid, and drawing with a stylus on an iPad in Limnu is impressive.

Andy W.

If the most authentic white board experience is what you are after, then look no further than Limnu.

The Limnu User Experience stands out amongst the challengers as one of the strongest, replicating the visual and almost physical experience of writing on a white board with markers. Not to mention, easy to understand and quick to navigate menus.

Matt G

Guys, I gotta say: I've been trying a few other tools and you guys rock! All in all we love it, the team would not work half as well without Limnu, you are total lifesavers!

Thanks a ton!

Rod L.

I love Limnu, as do my students. The feedback I get is that they love having me be able to watch them as they study.

I have seen such an increase in grades since I have started using Limnu as a study tool. It is awesome.

Shai M

Really excellent product. We work remotely full time with an office in Minneapolis and another in San Francisco but collaborate very closely and we've been looking for something like this. We've tried other ones and they've all frankly sucked. Yours is outstanding.

James D.

Limnu is fantastic. Thank you for addressing the need for a simple, collaborative brainstorming tool. We have staff working remotely, and a big frustration had always been sketching on our board and not being able to have those team members easily view what was being sketched or written.

Limnu not only takes care of that issue me, but also allows them to actually add their own input and ideas simultaneously.

Diego A.

Although there are other options on the market, Limnu stands out for its simplicity and quality.
