Lyft and Uber tend to have better prices than cabs. I keep both apps around because the difference in price can jump around quite a bit - sometimes up to 2-3x.

However, the ideal transportation if you're visiting is to simply walk around. It's amazing how easy it is to walk everywhere in SF. For Alcatraz, just grab a lyft/uber to the pier and take the ferry. By the way, if you have time the longer, late evening tours are quite interesting.
