Software to facilitate calm (7)

Ross

I believe the answer is:

appease

'calm' is the definition.
(appeasing is a kind of calming)

'software to facilitate' is the wordplay.
'software' becomes 'app' (software application).
'to facilitate' becomes 'ease' ('ease' can be a synonym of 'facilitate').
'app'+'ease'='APPEASE'

(Other definitions for appease that I've seen before include "Quiet" , "Calm, pacify, placate" , "Placate by giving in to demands" , "Mollify or calm by making concessions" , "be satisfying" .)

I've seen this clue in The Times and The Sun.
