We’re often asked what the best iPhone apps are. The truth is, it’s almost impossible to answer this question because what’s best for one user might not be for another. It all depends on what you’re trying to accomplish and how you want to do it.

This being said, there are many iPhone apps that we iDB editors, consider to be the best in their respective categories, and we thought it’d be a good idea to list them all under one single page.

Of course, this page will be updated from time to time because today’s best iPhone apps could be tomorrow’s worst. Things are evolving so quickly that an app can become obsolete in just a few months.

Make sure to check back often as we update our list of the best apps for iPhone.
