developing an app on ionic framework. looks really easy

is it tho? any experts around?

My experience is mostly based on Ionic v1, keep that in mind.

Really depends on what you want your app to do. We're currently building a (around medium sized) app with a lot of custom components and we're already having loads of performance issues on lower end devices, and even some midrange androids. But if you're planning on sticking with the framework and not doing anything too fancy it's great.

I would suggest investing time in v2 though, performance is much better and I find angular 2 more pleasant to work with.

@saDammie-Jr thankyou sir for the feedback. I really want to learn angular 2 can you suggest some good tuts?

I mostly just played around with it, but the angular '5 minute' build an app tutorial is a good read to get up to speed with the basics.

@saDammie-Jr let's say I have an angularjs app, I just want to make it an iOS app and enable vibration in one particular view. Worth it? Or should I find something better?

If that's all you're doing you can just slap it onto a cordova application and find a vibration plugin, something better would be react-native which probably would require you to rewrite most of your app.

Though you could try to port it to angular-2 and then wait for the angular2/react-native project to mature, but I haven't looked into that much as of yet.
