Putt & Approach are usually discs that have a speed between 1-3 and are generally used for shorter approaches or as a putter inside the circle. Some people almost only use the putter when it is time to put the disc within 10 meters, while others throw most of their shots with the putter. For the more inexperienced arm, the Putt & Approach can really help with keeping the disc inside the fairway and to get the technique in, try it yourself!
