Hello Adalo community 
I’m preparing to publish my Android app on the Google Play Store, and I would like to make sure the app is as smooth and optimized as possible.
I noticed there is an option during publishing that seems to make the app more optimized or flexible.
Could you please explain:
What is the best build option to choose for better performance?
How can I improve app smoothness and reduce lag?
Are there best practices to optimize database actions and screens before generating the Production Build?
My app includes interactive lessons and dynamic content, so performance is very important for me.
Thank you in advance for your help 
Hey @Wiseman,
Before publishing your app on app store or Google Play, I would recommend testing it on Apple or Google Play’s internal testing. In order to make sure your app is running smoothly, you can check the following points:
- (New React Native Version) is activated on your app’s settings.
- Use more native lists than custom lists, and make sure to activate the (Load items as user scrolls) in your lists.
- Avoid activating the (Auto Refresh) option in your list unless it’s necessary.
- Activate (Pagination) option in your list in case you have a lot of records to present.
- Avoid having a lot of components in one screen, especially multiple lists.
