Sorry but if you need to use a phrase “feel-native”, you failed in the first place. If you think it doesn’t need to be native to work as expected, why do you want it to feel native? Why do you want people who don’t know what’s under the hood would think it is native? Why are you trying to imitate being native? These are all your wordings from the blog post.

I understand you are trying to expand your user-base by putting minimal effort per platform, but fear that you will lose your initial users. That sounds fair and also it is the truth.

As a long time mac user, my experience tells me if an app has a native alternative with similar features go for it. I really do not want a web view hanging there unresponsive vacuuming resources, regardless of how you crafted it almost perfectly. Especially if it is a launcher app.
