What app do you use to take high-quality screenshots of the app to show on the landing or tutorial page if any?
You can capture screenshots inside Google Chrome. You can even take screenshots of individual HTML nodes when you right-click on an element inside dev tools. An option for "capture node screenshot" will appear.
If you need a large about of screenshots of your app, then my slightly biased input would be launchbrightly.com
We been working on automatic generation of screenshots, reflecting the latest version of your product, to eliminate the manual burden of updating them over and over again.
My 2 cents anyway! d/ :-)
I've loved this Chrome extensions for a while. Let's you grab a screen shot of the whole page.
