Is there an app for iOS/Android?

No, currently we don't have an app. The website should work perfectly fine on mobile devices.

As new features are added we will evaluate if a mobile app makes FreshBuzzer easier to use, e.g. with native mobile notifications and the ability to receive buzzer phone calls. Maintaining a high quality mobile app (or two in the case of iOS and Android) is a large effort for a small service like FreshBuzzer.
