Whitelists are not a question of popularity anymore, and they are way more accessible as of now. As long as whitelisted players have had a single interaction with you, it's enough for them to give your app a +1 or -1.
Grammar is important for an application. English is not my native language either, and I ended up having my first app denied because of it. I suggest that in case your app isn't accepted and you decide to do another in the future, ask a councillor to review it before posting.
You are still too new to be whitelisted, especially as a pred. I recommend that you play a few more months before making an app for any whitelist.
