Hi Amine, have you already launched the app? If I were you I would analyze the case of @Unhook (a Google extension to block what the algorithm recommends you). I think that you might get inspiration from what distribution channels they had success on.
Also, I would like to ask you if you think that your app might be a high-intent or low-intent product and how are you planning to take profits from it?
Hope I could provide some value for you. Would love to connect and share some more detailed ideas. Have a great day
