How to measure performance of angular app?

Question

I am working on big application built using angular. I have read a lot articles how to improve performance. I have implemented below mentioned things -

• Avoid Watchers
• ng-repeat with track by
• single binding
• Used ng-if instead of ng-show
• used $compileProvider.debugInfoEnabled(false) to remove ng-binding and ng-scope classes in production.

But I have tried a lot plugin but not able to get satisfactory result.

Could anybody tell me how to measure performance of angular app ??

I haven't tried it yet, but it looks promising: https://opbeat.com/angularjs

Other ideas:

1. Check how many watchers do you have: https://github.com/bahmutov/code-snippets/blob/master/ng-count-watchers.js

2. Check for memory leaks: http://www.dwmkerr.com/fixing-memory-leaks-in-angularjs-applications
