Great and Cheap (Occasional issues)


App is generally easy to follow and quite useful in class. 35$ for two year subscription is a great deal for use of paper in all classes and versatility for professors' questions. Only two times have I had issues where it wouldn't log me in due to saying I didn't have an account, but those were resolved by hard restarting the app once and getting off and on internet once. Great app, would recommend.



My Reef subscription has expired, but since then I purchased an iClicker and registered the remote. Even though this registration number clearly shows up in the Profile section of the app, I’m still being prompted to renew my subscription to use the app. Then, when I click the option to register a remote, I’m redirected to a website. I shouldn’t have to deal with all this rerouting. The system should know through the app that I have a registered remote and not prompt me.

We're sorry for the confusion -- the notification on your subscription status is only if you intend to use the Reef app to answer any in-class activities. If you're only using the remote to participate in class, you're all set! You can still use Reef for the study guide with no subscription needed.

Wish it had more notification settings


This is a pretty good app, although a bit on the basic side, however, when a new question comes up after the previous one, there is no indication whatsoever from my cell phone and/or other device that a new poll has begun. I truly wish there were more notification setting options, such as being able to set a tone/set a vibration notification that sounds when a new question appears.

That's a great idea, and something we're working to include in a future version. We appreciate you taking the time to give us some feedback!
