I use the Pro (i.e. paid) version of the app on an iPad mini 6 with a wired connection to my Sony FX30. It is a good app and has a much better user interface than the free “Monitor and Control” app that Sony offers.The biggest reason for me to use this app instead of the several cheap dedicated 5-7in hardware monitors sold in the market is the ability to control the camera (such as focus and iris) directly from the app instead of constantly jumping between the native camera screen and the monitor screen.Be aware though the controls don’t quite work if you close the FX30 native screen. This appears to be a Sony limitation because I noticed the same behavior even with the Sony-provided app.Anyway, the app works decent overall. There are quite a few UI quirks that can be fixed if the developer cares, but overall the UI is alright, efficient, and clear.But I noticed one big issue with the functionality. Using Zebra settings in the range mode with +/- 1 range, I am finding that the exposure levels measured by the app is very different from the levels reported by the Sony FX30 screen. It is off by about 5% around 50% range and a little less closer to 100%. I depend on false colors heavily to get my scenes exposed properly and an error of 10% is a bit too much to trust the app.Also, I have no idea why, but the app won’t let me set zebra levels below 50%. The camera’s native screen lets me go down as much as I want.Anyway, here’s my big problem. I have contacted the support email and contact form on their website for a total of five times. There has been absolutely no response. Not even an acknowledgement.The app is close to being an excellent alternative for dedicated hardware monitors and I’d love to see it get better. But if the developer is this unresponsive even for an almost $20 paid version, I wonder if we should bother with this app.

At the time of this writing, Monitor+ has a feature that was missing from Sony’s free Monitor and Control App: Stop-based false color, a useful way to view exposure. You can even use the “eye dropper tool” to select a point and see exactly how many stops over or under middle gray that point is. These are useful features. However, here is my feature wishlist for Monitor+. I wish Monitor+ would allow me to apply a false color or lut when reviewing already taken videos / photos. (Edit: workaround: When you push the “play” button on the camera, you can view taken photos/video with false color / lut because Monitor+ continues to apply the false color/lut to the input video signal which is the media you’re reviewing on camera.) I wish you could pinch to zoom on the preview image. I’d like to see the false color areas more clearly even if the resolution doesn’t change from the full screen image. - In photo mode, there is no way to “half press” the shutter button. You can long press the record button which performs the half press action (focus) but releasing the button always takes a picture which is not always what you want. It would be nice if you could assign a volume up or down button to mimic a half press. - Its not clear how well stop based false color works in photo mode. Is stop-based false color rec709 valid for the preview in photo mode? This may be a documentation issue. I thought touch to focus wasn’t working, but then I realized I needed to change a setting in the app. For many people, Sony’s free Monitor and Control app now has features that rival Monitor+, but Monitor+ still has some differentiating features like stop based false color.

monitor+ has brought tons of functionality to my smartphone at times when i dont want to carry around a full blown monitor on top of the hdmi cable, battery, etc, and it still offers just as much amount of value. maybe i just need a quick look at the scene on a slightly bigger screen, maybe i want to desqueeze my anamorphic lenses on a solo personal project, maybe im traveling and packing a monitor just isnt an option. this app does everything i need it to for my purposes EXCEPT one thing. i use the sony A7C II and like other newer models i can switch between photo, video, and slow motion video. when my camera is set to photo mode and i use the focus magnifier to check focus on my manual lenses the monitor also zooms in which is perfect; HOWEVER, in video mode the monitor+ app does NOT zoom with the focus mangifier, its a small gripe i have but a big one, it just slows down the process of me checking my focus while shooting video, if theres a workaround to this or this becomes fixed, i'd recommend the pro version of this app to every videographer i know. TL;DR: focus magnifier action does not work on monitor+ app when newer camera model is toggled to video mode

I was looking to add a monitor to my Sony A7sIII so that I could have access to features like Scopes and False Colors. There are a lot of great external monitors on the market that will give you these features, but this app also allows you to control many features of the camera, like exposure, focus, focus mode, white balance, codec, and fps, to name a few. This is awesome for me because I am a one-man band, and I am often in front of the camera as much as I am behind it. Having all this control while standing 15 to 20 feet in front of the camera is a game changer. The app also allows you to apply your favorite Lut and have the option of applying the Lut to the scopes, which is incredible. The app seems to be pretty stable on my A7sIII. I have had a few times that it has disconnected, but not enough that I have been frustrated by it. I have also noticed that on my iPhone 12 Pro, the output image does not seem to be as sharp as the LCD screen on the camera. This, of course, does not affect the recorded capture. There are a couple of features I would love to see added. First, I would like to be able to punch in on the image when manually focusing. This is a feature I use a lot on the camera’s LCD screen. I have tried using the focus assist on the camera, but it only does it on the LCD and is not transmitted to the Monitor+ app. I like the app’s peaking capability, and the greyscale option is a nice touch, but if I could also punch in, that would be really good. The second feature I would like is the ability to bring up the camera level. My camera is on a tripod most of the time, and my video head does have a level, but sometimes it can be cumbersome to see. That would be a major plus if I could get the camera level to show on the app. Overall, this app is head and shoulders better than the Sony Creator app and is worth the $25 dollar purchase price.
