I use Adam Fowler’s viewfinder app which is available at the app store for 4USD. It has a clean layout and allows you to store aspect ratios and format as well as focal lengths. There is also EV (exposure control) and a choice of film stocks. For me it’s ideal for testing out a location and exploring different ‘looks’ which fit my camera and usual lens choice.
