Actually, you can do pull list of friends who installed an app through FQL.

SELECT uid, name, pic_square FROM user WHERE is_app_user  AND uid IN (SELECT uid2 FROM friend WHERE uid1 = me())

You can do it like this also, if is_app_user=1 then its app user.

NSString *query = @"SELECT uid, name, pic_square,is_app_user FROM user WHERE uid IN " @"(SELECT uid2 FROM friend WHERE uid1 = me() LIMIT 25)";
