The last time I was in SF, I found that using Uberx and Uber Taxi was only a dollar or two more than taking a cab.

UberX is $1 more per mile than a taxi. Also, the minimum fare is $10 for UberX vs $3.50 for a cab.

Uber Taxi charges a fixed 20% tip and $1 booking fee.

Yea, I used it yesterday. It's not that expensive, the app is awesome, and their responsiveness is also great.
