I have extremely interested people in a FB group I run from where I can get a few K downloads per month easily.. I want to know if there is any sort of "Learn Spanish" app or course or something that is free for them to use and which I can monetize. I am aware of an app which pays 0.23$ per download for this exact thing but only for Turkish traffic. If there is any CPA network or anyone here who has any info in this regard please could you enlighten me. I would really appreciate such help. Thanks !
