Merlin version 1.0 gives you these powers:
|1| Play WebMs from Safari directly into a video player.
|2| Watch in fullscreen or overlay mode in app.
|3| Hear WebM audio or mute it.
[4] Play Gifs inline.
|5| Browse the web and watch video simultaneously.
Now in Merlin 2.0:
|6| Save videos locally and play them later
|7| Multiple tabs with independent video players.
|8| Dynamic WebM detection so Merlin is robust to website changes.
Merlin is tested and designed to work with 4chan boards.
A note on the handful of 1-3 star reviews: On February 27th 4chan made changes to the way WebMs are displayed on mobile, which broke Merlins WebM detection. It took several days to get a fix out on the app store. People who had paid for Merlin were understandably upset.
As of version 2, Merlins WebM detection is updated each time you open the app. If 4chan changes their WebM display again, it can be fixed the same day without needing to update the app. Thanks to those who reported the issue.
