Fiplab specializes in developing tiny applications that live in your Menu Bar, providing quick access to social networks—Google+, Facebook, and Gmail in the past. Now it’s developed an app for Pinterest. Pin for Pinterest is the free version, while Pin Pro ($1) gives you the same features but strips the ads away and has upload support.
Just click on the icon and your Pinterest feed pops down from the top of the screen; you can alternatively hit Control + P. One of the cooler features is the ability to switch between mobile and desktop interfaces. The former is better for taking a quick peak, while the latter allows more of an in-depth look and the ability to post pictures. There’s even a “ninja stealth mode” that helps hide your Pinteresting ways when at work by making the window as transparent as you prefer, so that you can still see Pinterest content overlapping whatever else you’re doing. If you’re an avid Pinterest user, it’s probably worth spending the buck on this one.
