One of my favorite screenshot managing apps on iOS, LongScreen, has been updated to support Apple Watch screenshots. This means that you can now combine multiple Apple Watch screenshots into a single screenshot, all on your iPhone.
The app, which is well-known for its ability to combine iPhone screenshots with padding and a cleaned up status bar, is now on version 1.3.
You can purchase LongScreen from the App Store for only $2.99, a price that's totally worth it when you consider the time that you can save from using it.
