Great app but only one problem.
this is a fatansitc app and is very useful, but in the 555 timer section you can only imput small values for capacitors, i.e. smaller than microfarads. In other words, you cannot enter a 4700 microfarad capacitor in the simulator. also there are no dual timers; that would be a nice addition.
Otherwise, it is a great app very useful. one of two apps that i use regularly for my projects.
