I can break last of camp’s tinder, say (6,3)

'tinder say' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'i can break last of camp's' is the wordplay.
'i can' becomes 'datin' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'break' becomes 'gap' (a gap is a break in something).
'last of' indicates one should take the final letters.
The final letter of 'camp' is 'p'.
'datin'+'gap'+'p'='DATING APP'

Can you help me to learn more?
