I had to create this app to demonstrate Ionic's performance to some customers, they needed to decide between use Ionic + AngularJS or React native, it was all about a company-internal use app to handle any kind of internal data.
They were not sure about the performance limits that Ionic and Cordova itself could get, actually neither I was. So I decided to create this really simple app similar to the most basics mock ups they provided me to really know how much we could get.
This is a really simple app that just consists of three views, a dashboard that lists 50 posts, a post's details view, and a user profile. It connects to RandomUser to get mock data for the posts. This was a good test to know how much we could get from Ionic. I also created a similar app using React Native to show them the differences, even though I was very used to work with RN.
Ionic definitely works pretty well, although using at least this app you can notice that there is an actual web browser there rendering the app. Even running it on a Nexus 5x when you scroll down and up you find that it is a little slower rendering results than it could be if it were made with a native UI instead. So, Ionic or Cordova by itself is a really good option if you have a web app and you need to create a mobile version, but it, of course, will never feel completely native. In this particular case, with this particular customer, they decided to use React Native instead, but I think Ionic is a really good solution for many cases, for sure something that I'm going to keep in mind from now on.
