When people think your downloadable software sucks, it’s generally hard to find out what you did wrong. Web-based analytics make it easy to track the number of downloads you get, but after that the information tends to dry up. That’s where Kampyle, an Israeli analytics startup, has found what looks like a good business opportunity. Its service will let you know if your software’s being used or immediately uninstalled. And it’ll tell you how many people even bother finishing the install process.

The company, which launched last spring with a service for gathering feedback about your dysfunctional web-based software, has expanded its reach to the desktop. Now, when half of the 223 people that actually bothered to download your program uninstall it, Kamplye expects to be able to tell you why.

When a user interrupts an installation process or removes the software later on, Kampyle opens up a small application. This app contains a checklist of problems that may have caused the abandonment and then a feedback form for additional comments. The checklist helps Kampyle track the most common source of complaints. It also offers a range of other data, like how long the software was used before it got axed. Finally, it collects the users’ email addresses, giving you a way to bombard them with news that your software’s crappyness ratio has declined by 15 percent.

The company says it will make the software free for the first few weeks and then start charging a subscription of up to $199 per month.
