Following suggestions for an app to help Wittertainees find other likeminded individuals, an app for your Generic fruit based device has been created by a listener to do just that. This app is not endorsed by the BBC, the presenters or, indeed, Witterpedia. However, at the moment it seems to work and comes with a handy copy of the Code of Conduct.
The app is on the Apple App Store: iWittr by Chris Mingay https://appsto.re/gb/YZ9Nab.i
There is also an Android version available called Wittr, also by Chris. https://play.google.com/store/apps/details?id=it.ct14.wittr&hl=en_GB
When Googling Wittr you may find yourself going to wittr.com, the homepage of American atmospheric black metal band Wolves In The Throne Room. If you have a quarter of an hour free you might listen to one of their tracks via the Wittertainment playlist.
Once again we must stress that the Wittr app is nothing to do with the BBC!
