I use the free version of Magic film viewfinder. It has film sizes up to and including 4x5, after that you need to calculate the difference in focal length of your lense.It has focal length up to 300mm. Lens wider than 90mm on 4x5 start to get cropped on my phone, havent found a way around that.
No adjustment to filters, you can hold a filter over the lens to get an idea, but films behave differently.
3 option of grids, grids dont show on taking a picture, just frame.
Maybe more options on the bought version.
