I'm trying to keep an open mind but even if the iPhone did work as well as my RHDesigns analyser 500 .... I don't want to be called when I am in my sanctuary. I would LOVE to have this LCD technology though so I don't have to bear under that Ilford 500 fan - that never goes off (even though it is supposed to) So count me in with the optimists that there may be a version compatible with the RHDesigns timers or analyzers.
Good luck!
