'pacify' is the definition.
(synonyms)

'phone widget with simplicity' is the wordplay.
'phone widget with' becomes 'app' (I can't explain this - if you can you should give a lot more credence to this answer).
'simplicity' becomes 'ease' (synonyms).
'app'+'ease'='APPEASE'

Can you help me to learn more?
