GH4 — Interest in using iPhone as wireless monitor?

tl;dr; Do you want me to build a better GH4 liveview app for iOS?

I'm a software developer and hobbyist filmmaker ... and two days ago I was wondering if I could combine the two and build an app that displays the GH4 WiFi video feed fullscreen on my iPhone (like the one in the Panasonic Image App, but fullscreen).

Long story short—I built a prototype that's good enough for my personal needs. It displays the live video feed from my GH4 on my iPhone in glorious fullscreen (err... "glorious" means what the GH4 is sending; a stream of 640x360 compressed JPEG images).

I'm considering spending some more time on the app and releasing it on the App Store, but I thought I should get some feedback before sinking too much time into it. Maybe it's just meant for me ...

Honestly I never use my iPhone for monitoring my GH4's recordings because I feel that I cannot rely on that wireless connection. I always use external monitors or recorders to do that. I only use the app to send the images from the GH4 straight to my iPhone so I can share them if I need/want to.
If you could do the same as manfrotto has done with an iPad and Canon and Nikon cameras that would be nice. So when you connect your GH4 with an iPad via USB and then you can monitor your screen with it. That would be very useful.

I hadn't seen the Manfrotto thing before. It looks like it has custom hardware between the iPad and the Canon/Nikon ... so for something to work with GH4 it would need that too. I don't know how to develop that hardware so that's a no go.

I found a few people who are interested in seeing this, so I've built a prototype. For anyone interested, send me a direct message on Twitter with your email address and I will add you to the iOS beta.

And here's a staggeringly non-cinematic video of me connecting my new app (Scopes) to the GH4. https://www.youtube.com/watch?v=OXARgM9LQjM

If it's already called Scopes, why not make it a real vectorscope/waveform monitor. there the delay wouldn't be that problematic and it's a feature that a lot of shooters really could use

I see you've predicted my plans for the app. ;)

This is great. Thanks for creating it, Marcus. Will you be making an android version?
