Ionic View and ionic run command gives different results - ios

If I test app in Ionic View on Iphone everything works great, but when I use run command to see app on real device with splashscreen it uses different rendering engine.

Shows up lags when clicks and some delays during execution.

There is a way to get the same results in published app as in Ionic View?

If no - what is a bonus of using Ionic View to test something?
