Used the remote during medic class tonight. I was able to run things while moving around the room. As noted in the description this is not a stand alone ap. Dartsim is on my ipad. The remote ap on my iphone allows me to change rhythms and readings on the ipad.
I did have some connection issues originally. But those were quickly solved. I did contact support by email, they responded quickly with the needed information.
