Mobel is a bell ringing simulator for church bell ringers and handbell change ringers. It runs on iPhone, iPad and Apple Mac. When ringers are at home, travelling or at towers, Mobel lets them practise any method they are going to ring. It also shows the blue line diagram for any method, including bobs and singles.

Practise any method on 4 to 16 bells.
Ring plain courses, or touches that Mobel creates (including spliced). Add your own touches (compositions).
Ring any bell; handbell ringers can ring any pair.
Mobel rings the other bells, and speaks any calls.
Conduct: put in bobs and/or singles yourself.

See the blue line diagram for any method or composition that you have added.
Line styles with or without the underlying bell numbers, or as a grid.
Lines for bobs and singles.
Pinch to zoom the diagram.

Mobel comes from AbelSim, producer of the world's best-selling change ringing simulators: Abel for Windows PCs and Mabel for Apple Mac (see www.abelsim.co.uk).

Mobel is not intended for handbell tune ringers: it rings changes, not tunes.

The latest version runs on iOS 9 and later. Earlier versions of Mobel are still available for previous versions of iOS.
