How are you building the app? Do you have any “crazy” start-up logic? Are you using the latest ionic-app-script? ---

Sorry, I mostly meant are you building with `--prod`? You should also try updating your ionic-app-scripts. ---

Are you using lazy loading? If not, you should. Moreover, in your config.xml use the following, it will speed up the loading process: ```auto ``` ---

Inner pages work fine because when you launch the app it loads all pages to memory -when you are not using lazy loading- which results in long loading start-up time. Try it with Lazy Loading [lazy loading part 1](https://blog.ionic.io/ionic-and-lazy-loading-pt-2/) and [Lazy loading part 2](https://blog.ionic.io/ionic-and-lazy-loading-pt-2/). ---

What is your `ionic info` output? What is the exact command you use to build your app? How many pages do you have in your app? Do you _really_ use all those native plugins? Stripe, Braintree and Paypal? ---

@amjadyahya i think lazy loading doesn’t work in ionic 2 ---

There you go, having 90 pages to load at startup is causing the app to launch in 24-26 seconds, upgrade to ionic 3 and start using lazy loading, there is no solution for your current situation unless you use ionic 3+. ---

@amjadyahya any alternate option except ionic 3 ---

All of it to the newest if possible. Otherwise, whatever you are comfortable with and can handle.
