LongScreen is a simple app for combining multiple screenshots vertically or side-by-side automatically.
Here’s how it works：
• Take screenshots you want to combine， open the app and give it access to your camera roll.
• Tap and choose multiple screenshots from the gallery， choose your merge option， and you’re done！ The LongScreen algorithms will analysis those screenshots and combine them together.
• The processed screenshot can be saved back to your Camera Roll， sent in Messages， copied to clipboard， posted to Facebook or Twitter， and more.
• Enhance your iOS workflows using x-callback-urls
