Ask HN: Which software you use has the best user experience for you?
Could be an App, Website or a script.
The best user experience is when i never feel like the app 'gets in the way' or 'slows me down'. Everything mobile or built with javascript (damn spinners!) fails in that.
If you want to spend a few minutes with it, you can find the link in my profile... If you have feedback, there's a Write form on the page you can use.
