Ionic App Slow App Start

The build is happening on Ionic Pro servers. I assume --prod tag is being used. What else could be done to improve the speed of the app loading??

You will need to give more details to receive meaningful answers, there are many things that impact application performance and a lot of it comes down to the way the code is designed. In general, the big factors that can improve startup times are:

  1. Creating a production build
  2. Using lazy loading
  3. Ensuring that you are hiding the splash screen as soon as the application loads

We are using the build process with Ionic Pro. Does that not do a production build?

What do you mean by lazy loading?
