This is a nice web app.

However, I still feel not comfortable with HTML5-ing each and every task when there are decent desktop tools around which have been working for decades. I am no longer surprised that for almost every second shiny web tool there is a more or less matured C standalone tool available.

In this case, take a look at http://www.frantz.fi/software/g3data.php I have used in on my production machines (not a smartphone, sorry) for decades. And the best thing was: I never had to think about clicking or reading a Privacy statement or whatsoever.

I am the creator of this app. I made this as a fun side project during grad school, but kept working on it as my friends or I needed more features. Over time it has become fairly popular and now I am thinking of making a traditional desktop software as well.

The main reason I built this was that existing tools (including G3Data) were either tedious, did not have any sub-pixel level accuracy or were limited to simple XY plots only. I took a very simple web based approach as it was easier for me and I could get this to work on virtually any computer in the lab that had a browser and internet.

I posted it not because it is in the web, but because it is powerful. For example: automatic extraction of barplots of selected color.

Before I explored tons of applications requiring to manually click of the every single point. And actually I am hoping for an app automatically getting scales and coordinate system.

Automatic extraction of scales and coordinate systems is a much harder problem (http://xkcd.com/1425/).

Some advantages of web apps is that they are multi-platform out of the box, don't require any setup or admin privileges and don't require installing dependencies (e.g. the link you point to, while looking like a really great product, depends on gtk).
