Last week I mentioned an iPhone app for creating and exporting framed app screenshots with text, and earlier mentioned a couple of command line tools for automatically taking screenshots, and modifying screenshots in batch.
Here’s an open source tool for creating app store images in the form of a Sketch plugin with a nice set of features called Sketch To App Store from Cluster.
Sketch to App Store allows you to make screenshots with a device frame, screenshots only, and will automatically export the screenshots at every resolution Apple requires, or whichever size you select. You can add in your own content including Sketch symbols and text styles.
Here are a few images from the readme showing some screenshots created with Sketch To App Store.
You can find Sketch To App Store over on the home page.
