So I was able to connect my iPad and iPhone to the Mod Duo using a USB cable to a lightning port adapter and it worked great! I just used Chrome and logged into the Mod Duo’s address and the interface was completely workable. I even updated the Mod Duo’s firmware to the latest version using my iPad! Pretty impressive.
The only issues I had was that the bottom menu was too big and didn’t size well on my iPhone, but it was totally fine on my iPad (then again, everything was too small on my phone). Secondly, the knobs were a little hard to adjust, so I have to figure out the best way to do that.
I would say that if anyone was going to use IOS with their Mod Duo, then I would suggest using at least an iPad Mini or a mid-sized tablet.
