I'm shooting a promo video for an app and we're showing it on both phones, tablets, and laptops. Mostly apple and then couple chromebook/android. I know apple has the better displays for videoing. In the past my 5d3 just showed nasty moire on the screen. Anyone have any experience using it in this environment with the c100?

Have you looked into digital screen replacement? I suspect that's your best bet.
I believe the OP's post was about shooting video of an actual smart phone/mobile screens using the app, unless I am mistake.

Ever notice the disclaimer "Screen images simulated" on just about every smart phone ad? It's not that easy to get the right image to show up at the right time while shooting a phone, so the replacement in post is often easier to do. But I guess it depends on what you're trying to accomplish and what kind of time/budget you've got. The last time I had to do one of these with no budget, we shot a medium shot with the focus on the person doing the demo and didn't do any close ups on the computer screen, but just cut to screen captures to show any key details. That worked just fine for them since it wasn't a touch interface.
I haven't had any issues with fine-density displays on C100 or Alexa. I have found bad aliasing with both on high frequency red fabric patterns, so high frequency red might do it on a phone, too.
99% of the time I will do screen replacement, but for typing I have had to use the GUI keyboard in the past with success so it lined up and then just modify the rest in post.
I have had no problems with aliasing when holding the phone reasonably close, but I do still use screen replacement 99% of the time.

NO PROBLEM. I recently did a Kickstarter video for an app developer on smart phones and had no moire or aliasing. I have that issue with certain models of desktop screens though. The one bug I found is I feel the screens are closer to daylight than tungsten so you have to cheat it.
If you email me at: ned AT nedmiller.com I will send you a link.
At certain points the editor froze the close up footage and did some tweaks to the screen because app makers are never "done" with their app, so some graphics needed to be added later. Also glows, arrows, circles, etc.
