Download history

The number of downloads of GpsPrune has increased steadily over the months as the program has become more useful and better publicised. Some landmarks:

September 2006 - first version made available for download
November 2006 - downloads exceed 10 per month
April 2007 - total downloads exceed 100
August 2007 - downloads exceed 100 per month
January 2008 - total downloads exceed 1000
October 2008 - downloads exceed 1000 per month
January 2009 - total downloads exceed 10000
October 2009 - downloads of version 7 exceed 10,000
May 2010 - downloads of version 10 peak at over 100 per day
August 2010 - total downloads exceed 100 per day
October 2010 - both Debian's and Ubuntu's popcon tools show more than 100 installs each
March 2011 - total of Debian's and Ubuntu's popcon tools show more than 1000 installs
November 2012 - total downloads exceed 100,000
May 2013 - Debian's popcon tool shows 100 "regular users" (not just installs)
May 2015 - Ubuntu's popcon tool shows more GpsPrune votes than Viking votes for the first time
May 2015 - Debian's popcon tool shows more GpsPrune votes than Viking votes for the first time

There are a few reasons why these numbers are horribly inaccurate. Firstly, they may underestimate the real number of downloads because of alternative distribution methods, other websites offering Prune downloads, downloads from linux package repositories, people emailing or copying the files around. But more realistically they hugely overestimate the number of downloads from this site because of crawling bots, because of people downloading the file more than once, and as I recently discovered, because the webalizer software also counts log entries with status code 206, which isn't a real download, it's a partial download. So if a client takes several requests to download the jar, webalizer unfortunately counts this as several downloads. I can only assume that this is a webalizer bug.

But, even allowing for the poor accuracy of these absolute numbers, they're still useful to look at the increase in the number of downloads - it's clearly showing a continual increase in the popularity of the program.

Most popular versions: version 13.*, version 18.*, version 17.*, version 15.*, version 12.*, version 7, version 16.*.

Most popular months: August 2010 (release of version 11), September 2010, May 2010 (release of version 10), July 2012, June 2010, May 2011, June 2012.

Popcon

It's not always easy to work out how many people use GpsPrune. Users don't need to pay money, or register, they can download it from anywhere and run it anywhere, so I don't know whether people are using it or not. Especially because GpsPrune specifically does not track its users, or phone home, or use any such tricks. So how can we see how popular GpsPrune really is?

Debian popcon graph

Well, we can't tell any absolute numbers, but some GpsPrune users use Debian Linux, and some of those users also use a Debian tool called popcon which reports (anonymously) back to the Debian project which packages are being used. It's only a small subset of users, and obviously the absolute numbers don't mean anything, but what we can do is compare GpsPrune's numbers over time, and compare GpsPrune's numbers against other, similar packages.

The graph on the right shows the relative popularity of GpsPrune (red) compared to Viking (in green) over time (until April 2013). Viking is much older than GpsPrune but shares many features. The focus is different though, Viking is much more oriented towards a traditional (and powerful) GIS tool, whereas GpsPrune aims to be easier to use for regular GPS users who just want tracks and maps.

The horizontal scale of the map goes from GpsPrune's entry to Debian in 2010 to the present (April 2013), and shows how Viking has always had more users. Both lines were fairly flat throughout 2012, but excitingly GpsPrune is currently hot on Viking's heels and may soon have more (Debian) users than Viking! It's currently nail-bitingly close.

Update 2015: Ok, so two years later, and that enthusiasm was a little premature, but as of September 2015, Debian's stats show that GpsPrune finally has more 'votes' than Viking. This is probably only temporary due to Viking's recent release, but even so it's a milestone for it to happen for the first time. Also in Ubuntu's stats, GpsPrune's "vote" count (people who used GpsPrune recently) is now (since May 2015) also greater than Viking's "vote" count! The number of installs of Viking is still much larger (by a factor of over 3), but if those numbers are accurate, GpsPrune currently has more Ubuntu users than Viking does!

There are other comparisons one can make, for example (on Debian) GpsPrune has had many more users than gpscorrelate or gpxviewer just to name two. On the other hand, there are well over three GPSBabel users per Viking user, but less than half of one gpsbabel-gui user. As well as many command line users of GPSBabel, I hope people are using GpsPrune as a gui for GPSBabel's functions, especially since the new filters became available in version 15.

To do

There are several additional features planned which have not yet been implemented. The current status of development is shown in the development page.

Of course any suggestions or contributions, especially multi-lingual translation expertise, would be very gratefully received! Please see the translation wiki for details on how to help with this.
