We're seeing developers who are active about modifying and
updating their apps be
more successful on a regular basis. This is because the updates
mechanism creates an opportunity to re-engage with customers who
might have forgotten about your app or who gave up on it. Each
update serves as a reminder of your existence.
Additionally, regularly updating your app communicates to your app customers that you are regularly investing in their experience. You don't want to go over board with updates (we've seen apps trying to update every few days or every week) because the take rate on your app updates does send signals to the app stores about your activity. You want to find the balance between your app seeming like it's dead and updating so aggressively that very few people have the most recent version.
