SCORE: 5 / 5
NOTE: This app is Wi-Fi / ONLINE only!
Probably my favorite in my collection of app-finding-apps for the sole reason of its easy-to-use wishlist notifications. Load up Appshopper (via your device or your PC), sign up for an account, then search for any apps that might interest you. With full details and easy browsing via category, price options, and more, AppShopper also notifies you (based on your preferences) if an app in your wishlist has gone down in price, up in price, or has been updated in any way. Waiting for that one special app to become free for that one single day? Let AppShopper keep tabs for you and be ready when that day comes!
RECOMMENDATION: Thus far not only have I found absolutely nothing wrong with the app technically, but its ease of searching and prompt wishlist notifications have pretty much made it my default, "instead of the app store" app browser.
