Note: This review is specifically written for iPhone; other devices may vary.
This app, alone, works fairly well. I rarely ever get dropped from sessions, and it holds a lot of basic functionality. Currently, the app holds the functions to be present, to view the whiteboard, raise hand, step out (automatically done when app is in the background), use a green check/red x/other, and emoticons. On top of this, you have the ability to swipe the screen left, opening the participant window, or swiping right, opening the room view, which also presents the ability to view different settings, or leave the session. If given permission by a moderator, you make talk over the microphone, with fairly good quality. Likewise, if chat is open to everyone, you may use the chat, which can be very effective when paired with dictation. This, however, is the first of the problems presented. The chat function is extremely limited in what it can do, only giving the option to chat to everyone. In this version, you are unable to send private messages to anyone, including the moderator. What I would do, from a design point of view, is to bring this functionality in, by incorporating the ability to select whoever you want to send a private message to, though the participant window. In addition to this, ether add a "Open Room" button, or a "Multi Select" button, where open room would set you back to chatting publicly, or a multi select functionality would allow you to choose between selecting multiple people, or clicking on an already selected participant in order to go back to public chat. Due to the ability said above to select multiple people, changing chat from personal conversations wouldnt be as simple as clicking names. Therefore, one could either simply see all messages at once, or have the ability to surf through conversations while the chat screen is open.
Next on this list is the ability to use the whiteboard. On many occasions, I will have to log out mid-class and switch to a computer because I get sent to a breakout room, required to use the whiteboard. I feel that a whiteboard editing functionality could be easily implemented into the iPhones landscape mode, which already makes the whiteboard the only on-screen object. This, paired with the ability to zoom using two or more fingers, could be a very effective means of editing. The editing tools could show up upon tap, like the other buttons, such as the microphone. Once an editing tool is selected, all the icons could disappear, zooming functionality would be essential to remain, and a simple X could appear in the corner to exit edit mode, or perhaps, just simple make it exit on release of landscape mode. In addition to this, the ability to switch whiteboard screens would be necessary, either by swiping to the side (which would present an annoyance in some cases), or potentially by having a selection, much like the computer version.
While I am unsure as to what the original intention of this app was, the intention I receive is once of an emergency app. Thus, Im full filling the apps true function, only being useful when stuck in traffic, and at least being able to listen to the teacher, or being stuck elsewhere, keeping basic interaction. While this, in itself, can be useful, I feel that it is an unnecessary limitation to an idea which could open up new doors to the company. By integrating the ideas said above, this app can achieve independence from the computer version, and thus, whole new opportunities arise, surely increasing popularity, especially in todays world, where advanced smartphones are owned by too many people to count. This is a method of learning which has opened more doors to schooling than ever before, so why not take it further, and appeal to a whole new crowd, while keeping your current ones? Nothing but good could come from it.
