Hello,
When making a thread like this please include the name of the application in the title. People searching for information on an app such as barcode besties will likely never stumble upon a thread called "i love this app". This will help more people find the app you love and therefore help spread the word.
Another thing, which helps spread the word about an app is to place it in the applications forum so people on all devices can see it. By placing it in an device specific forum, people not on that device have a slim to none chance of ever seeing your post of the app. An exception to this might be if an application should work on your phone but due to something specific with the device (looks at LG for disabling stagefright in optimus series) the application won't function. This would not be a limitation of the app but rather a problem with the phone in which case should go into the device specific forum so anyone reading about this phone can see that there is a problem with a specific app and that phone and can use that information in their decision to purchase the phone.
Also, please include information such as price, what's it do, why would someone want it. People reading this will want that information. No need for a full blown review but please try to give a general idea of what the app is.
Thanks,
K.P.
