ios - Do you have to make a separate app to make a paid version? -

i have app , want know, if want provide paid version that's ad free, have make totally separate app? 1 app has ads, , have remake app without ads?

probably best practice make full version of app limit functionality. provide in-app purchases enable functionality limited. can @ once or in parts.

for example, game level 1 free, levels 1-5 $0.99, levels 1-10 $1.99, , on.
