BB10bars.net released 80 new requested bars today, I tryed 3 of them : Shazam, Google Calendar and Gifboom (my request), and only the latter works. It an old version of the app though.
So add to the list : Gifboom GifBoom : BlackBerry 10 Bars
By the way, for those wondering, here's the answer I got from Gifboom regarding a blackberry 10 app :
"Hi,
Currently, we have iOS version and Android version. We may develop a Blackberry version in the future.
Thanks,
GifBoom Team"
