Even so, it's still tough to sort through the sheer volume of stuff. There is no search function in AppSniper. It is very much a browsing experience.

The app requires a Wi-Fi or 3G/EDGE connection to work. You need to enable the 3G/EDGE function in the app's settings, however. Why this isn't a default, I do not know.

A couple of additional caveats: Although AppSniper updates price information regularly, you absolutely must double check the price as it appears on the App Store. Sometimes, the price you see on AppSniper isn't the same as the actual price. Also, AppSniper is hardly the only way to track price fluctuations at the App Store. You could follow on Twitter, for example.

Earlier versions of AppSniper were buggy memory hogs. More than once I received a message warning me that the app has "detected a low memory condition" and instructing me to restart. The problem seems to have been resolved with the latest update, however. I haven't had an error since downloading the update.

AppSniper might not be the ultimate bargain finder for savvy app shoppers, but it does yeoman's work if you have the time and patience to browse.
