How to update my app without going through the app store

how to update my app without going through the app store.??

Check this native plugin codepush, you can commit an update each time you made same changes in your code without going through the app store.

code push is different from ionic deploy sir?

Same principle, just a different implementation by different people.

As Ionic is deeply integrated with Ionic Cloud, I suggest you trying “Ionic Deploy”. Works quite well for most people.
