When participating in a conference call, it is often helpful to let everyone on the call see a shared screen at the same time. GoToMeeting from Citrix is software that let’s you do exactly that. If you use the free GoToMeeting app, you can view the shared screen on an iPad or iPhone. I haven’t tried doing so on an iPhone yet; it seems to me that the shared screen would be very small, although I suppose if you were out of the office and only had an iPhone with you that could be better than nothing. On a large iPad screen, however, the GoToMeeting app has more than enough space.
I used the GoToMeeting app during a recent conference to get some screenshots for this post, but unfortunately I cannot simply show you the actual images without revealing confidential information. Instead, I redacted large parts of these images, but trust me that I saw everything on the iPad that I needed to see. During that meeting I actually had GoToMeeting running on both a computer and my iPad at the same time just to confirm that everything I could see on my computer screen could also be seen on the iPad screen — and yes, it was the same.
To participate in a meeting, just start the app and enter the meeting ID, along with your name and email address. Or, if you receive a meeting invitation in an email, you are supposed to be able to just tap on a link in the email, although I haven’t tested that yet. Note that you can only participate in a GoToMeeting conference with this app; you cannot currently initiate the conference from an iPad or iPhone, although Citrix says that this feature is in the works for a future update. [UPDATE: It appears that feature is now added, although I haven’t tried it myself.]
In just a few seconds, you will see the screen of the person sharing their screen. It will look something like this, without the big blue redaction box:
In my prior experiences with conferences like this, it works best to have a regular telephone conference call and then use GoToMeeting just to share a screen and not audio. Having said that, I understand that the app will allow you to listen and talk, if that is how the conference is being conducted.
If you tap the people icon at the top, you can see a list of who is participating in the conference. You can also “chat” (like instant messaging) with a specific person on the call or with everyone on the call.
Instead of or in addition to sharing one person’s screen, I understand that it is also possible to use GoToMeeting for a videochat. I haven’t tested that feature, except to tap the camera button to see how I would go about sharing my camera.
The settings icon will let you get information on the call or change some of the basic settings.
Although the iPad screen is smaller than most computer screens, I actually think it is better for a task like this. First, you can easily pinch to zoom the screen up to 3x. That’s larger than you will see on your computer’s monitor, so with a simple gesture you can see all the details that you want. Second, I like being able to devote my iPad to the shared screen of the conference and constantly have it shown while I use my computer screen to type notes or look something up in a file. In this way, the iPad is a substitute for a second monitor on the computer.
There is not much more to say about this app. It does what you would expect it to do, and it is free. The main reason for this post today is to alert you that the app exists. The next time that you are asked to participate in a conference call using GoToMeeting, I recommend that you download this app and see what it is like to participate from your iPad.

GoToMeeting is a great program. I used to love it before I discovered Google Hangouts.
