Interesting concept
The assumption underlying the approach taken by this app is that since students spend a lot of time online, digital classroom interactions will increase student engagement. Personally, I'm suspicious of this approach, and I prefer an old-school teaching approach that incorporates new technology but focuses on verbal interaction. I use Keynote for presentation software so I don't have to spend time writing on the board (the iPhone Keynote Remote app gives me the freedom to roam the classroom), but I've banned students from using any electronic devices in class. Experience has shown me that students who use laptops take poor notes, preferring to act like stenographers rather than active listeners. On the face of it, this app appears to avoid that problem, and I applaud their efforts, but I remain suspicious because it intentionally helps students avoid verbalizing their ideas or condense what the professor said into their own words. There is a lot of value in having students actually write down notes by hand and speak in class, believe it or not. Increasingly, students don't like to do it, but it's still good for them. My underlying belief is that technology should be a tool not a crutch, and I feel a need to push it into the background as much as possible. Being able to articulate an idea verbally and take good notes are important skills that I fear is being lost in the shift to a more online-oriented approach, and I think that the only way avoid this pitfall is to focus the classroom on that kind of interaction. For me, it's not just learning the material, it's also about learning how to put that material to good use. I'm a history professor, by the way, so maybe I'm still a bit suspicious of technology for its own sake, and I certainly don't want to sound dismissive of this app, which might be extremely useful if combined with other approaches in the classroom. I just want to make sure that we're not throwing out the baby with the bath water.
