Flipagram is an online and mobile application that allows users to create unique and engaging stories using photos, videos, and music. It is especially popular for creating slideshows for sharing on social media. It provides a wide range of tools for creating beautiful slideshows, including customizing them with captions, text, animations, and filters. It also offers a library of royalty-free music to add to slideshows. Users can also share their creations with other users and on other social networks. It is available on iOS, Android, and the web.
Boomerang makes 2 second clips that have a bouncing motion for Instagram. Not at all an alternative for Flioagram, Flipagram is its own social network that you can make videos and then share them on your vlog.
