I think it would be best to change :
Play smart with\nyour speed of choice with : Modifiez la\nvitesse de lecture
And I don’t really like translation for “Adapt AntennaPod\nto your needs” but can’ find better.
Maybe using “No adds or in-app payment” would be better than adapt to your needs. (And translation for french would be “Pas de pub et\ntotalement gratuit”
