Will you support other Wi-Fi-enabled cameras, like the Sony FS5 or A7 series, etc.?

I plan to add support for Sony hybrid camera (A7 series, a6000 series, etc.) in the near term. Beyond that, a lot depends on whether the camera has a published wireless interface, and whether it transmits video in a form that iDevices can decode.

Teradek supplies an iOS SDK (software development kit) with code to discover and connect to Teradek transmitters and decode their streams.

Supported Panasonic cameras send JPEG streams over UDP, and their HTTP command language is unencrypted, so the basic interface was easily reverse-engineered by clever folks at personal-view.com. Once I saw that, it only took a few weeks of looking at data dumps captured using CocoaPacketAnalyzer, along with custom iPad code, to suss out enough to make the GH4 and GH5 work.

Japanese camera companies are very conservative and don’t like to expose their communications interfaces to third parties, so I can’t promise anything or suggest a timeframe when—if ever—such a thing might occur for a particular class of camera.

What about a version for Bolt or Paralinx transmitters?

Bolt and Paralinx send low-latency uncompressed video over the 5GHz frequency band, but they don’t use Wi-Fi signaling and, so their signals can’t be received by iDevices. And even if they could, the data rates would be scandalous!

Some crews simply connect a Cube to the output of a Bolt or Paralinx receiver, and rebroadcast the video for iPhones ‘n’ iPads.

There’s only one “settings button”; there’s no false-color control!

You have an older iDevice that doesn't support false color. False color requires iPhone 5S or later, iPod touch 6G or later, iPad Air or later, iPad mini 2 or later, or iPad Pro.

Is this the same thing as Wi-Fi WFM?

Yes. Wi-Fi WFM is evolving into FieldMonitor. Once FieldMonitor is released, updating Wi-Fi WFM turns it into FieldMonitor.

Where is the Android version?

I don't have one, sorry. I’m busy with iOS work, and besides, there is no Teradek SDK for Android.

I'm a student: can I get a discount?

FieldMonitor will be available through Apple’s Volume Purchase Program for education. Your school can buy 20 or more at half price, and give you a code to install it on your iDevice.

Sadly there’s no good online description of the Volume Purchase Program at present, though it’s briefly mentioned here, under “Apps at a volume discount”, and there's some deployment info here. For more details, contact the Apple technology manager or IT folks at your school.

Who needs to see YCbCr WFMs?

I've never needed it myself, but Alex Lindsay said it was essential. So there it is. Who am I to argue with Alex Lindsay?  :-)

Why isn’t my question answered here?

Because I haven’t heard it yet, that's why. Ask me and I’ll see if I can answer it.
