Is there any offline support?
The review session marks cards correct or incorrect in the background while you do your reviews, this means that when your internet connection cuts out (while on the subway for example), it will automatically retry a few times to mark your answered cards once your internet connection comes back.
Aside from that, there isn't any further offline support as of now, sorry about that! However, we are working very hard on the mobile apps and one of the things we'll make sure of is that it will have offline support at a later point.
We know that offline support is going to help you learn the subjects you want here in Kitsun in a much more convenient way so you can be sure that we're working on getting that going as soon as possible! Stay tuned!
