If you’re looking to find out what apps you should install on your iOS devices and which ones are popular among your friends, you might consider checking out Frenzapp by Singapore-based Bitsmedia. This free, cleanly designed app automatically discovers apps installed on your device and compares them to what your friends have on theirs.
Since it hooks up directly to Facebook, the entire process of friend finding is limited to simply asking them to install Frenzapp on their iPhones, iPod touches or even iPads. While it’s not a universal app, it works on iPads just as well. The latest version uses Facebook’s single sign on which means if you have the Facebook app installed and signed on, you don’t need to enter your Facebook credentials on Frenzapp. It then will immediately search the network for friends who also use the app.
Frenzapp not only finds your apps but it also recognizes the ones you’ve used most recently. You can tell the app which ones you like best and which ones you want to hide from your friends in case you don’t want them to know you’re a big fan of Glee for example. It also tells you what apps are currently on sale, which is useful if you’re a deal hunter.
Macworld went one step further to find out how Frenzapp manages to do its app discovery without getting slapped by Apple’s app reviewer. As it turns out, it uses the same method that file management apps like Good Reader use to see what other apps can open a particular document. That is why Frenzapp manages to see some apps but not others. Those apps that have data sharing enabled will be picked up by Frenzapp. Those who don’t, won’t.
The power of Frenzapp won’t be realized until a large number of your friends install the app on their iOS devices as the entire mechanism is based on human recommendations. The app heavily relies on Facebook so if you’re averse to the largest social network on the planet, unfortunately you’re out of luck. Otherwise, it’s arguably a better way to discover apps that are relevant to you than Apple’s own Genius tab on the App Store.
