Mentimeter

Mentimeter allows you to easily (very easily) create and launch live, interactive polls, surveys and quizzes and create cool things like wordclouds in real time. It has a really smooth mobile integration through the use of QR codes which is a killer feature in the modern age. We have frequently had "wow moments" in meetings, workshops and training sessions using Mentimeter as people see animated quiz standing come in in real time and the like. Zero learning curve from the users point of view and almost frictionless.

It has a few limitations that make it less slick from the point of view of the person using it compared to the people answering the questions. It does not integrate well with Powerpoint. There is an outdated and never updated plug in which crashes all the time and thus unusable. The other option is to import your slides into Mentimeter and do the whole thing from there. This is not always advisable because animations are not preserved and the general look of the slides suffers.

Without PPT integration, if you are running a remote session using Zoom or similar you are forcing people to navigate away from your window to use Mentimeter and then relying on them coming back to see the results come in in real time. It damages the experience tremendously. You get around this by showing QR codes and having them do it on their phones, but still, not ideal.

Another issue is that moving or otherwise adjusting slide shows inside Mentimeter is a huge pain. Drag and drop to change the order of slides is basically broken, so me and my team always make sure everything is in order before importing (if we even use importing, see above). Even a no-integrated session with more than a few Mentimeter slides is a huge pain to adjust.

Finally, although they claim that switching between say PPT and Mentimeter on the fly is easy, it inhibits you from easily and smoothly moving to the next question. Not ideal.

Has numerous features to add interactivity. Functionality is easy to grasp.

Uploading a presentation proved difficult, despite it meeting the designated parameters. All of the options such as quizzes, polling, etc were greyed out and couldn't be accessed. The basic option is really basic. I upgraded to get enhanced functionality and instead got nothing.
