A slightly different take on 2011. While everyone is rehashing the news, I'll just go through the list of apps on my iPhone and see which apps really stuck during the whole year. Is this list useful? Probably not, unless you are interested in what I have on my iPhone or you are looking for something specific.
How do I know which apps to choose? Well, apps stay on my iPhone when I use them. If I do not use them for a few weeks, I remove them. I won't list apps that were recently released here.
Tools (links open iTunes):
The above tools have been installed on my iPhone for a long time, and get (almost) daily usage.
No, Google+ did not survive 2011.
Those are all the apps that have stuck throughout 2011. Some were released in 2011, but most of them have been available longer and have only been updated. Special mention for Path, which must be my most-used app.
A request for Apple; I'd like to (automatically) organize my apps by times used. So I have the most used apps within easy reach. Yes I can do that manually, but it's extra work, and I'm kind of lazy.
Of course I have more apps on my iPhone, but most of them are cycling on/off the device. Others I install and after some time remove because I just don't use them. And some are only there when needed (e.g. Navigon US West, I'm not there that often)
