J2ObjC vs PhoneGap

Looking for some advice: we are planning to create a hybrid app for both iOS and Android; this app will consume a REST API. We are looking for a tool for this development with the following attributes:

• Shallow learning curve; easiness to adopt (all team is new into mobile development, with diverse backgrounds: Java, Python & AngularJS),

• Easiness to test (we discarded Angular-based tools already: creating a unit test in Angular we considered time-consuming and low value. At this point of the project, we cannot afford UI testing with Selenium/Appium based tools).

• So far, we are not considering any specific capability of the device. Still, in the mid/long term, we would require the usage of GPS (geolocalization) and accelerometer (not sure if it's possible to use it from a hybrid app). Suggest any other tool if you wish.

I've yet to see a non-native application that I felt performed as well and/or provided the same user experience with Cordova/PhoneGap/Xamarin. Frankly, at best they all seemed like underpowered web applications deployed to a sandbox that ran on a phone. They didn't feel "slick" or "mobile-first" and in some cases the performance was unacceptable. At previous companies, we built a few of these apps at the client's insistence, and in every case, they re-engaged us about 18 months later to re-write the app(s) natively.

We are doing some research on React Native and Flutter, but I am not yet convinced that they can provide the same level of experience and performance as native, though I am trying to keep an open mind.

Hi Manish,

Well between those 2 options (Kotlin and Flutter), Flutter would be the only one that would allow you to make your app for both Apple and Android. Kotlin is for Android only. But there are other crossplatform development frameworks besides Flutter. Which one is the best for you would depend on the app you want to create and your current expertises and preferences. I've marked a few alternatives in my answer.
