is CounchDB mobile supported (or will be in future)?

Right you are (sorry I did not notice the “local” bit in your post).

I use sqllite3 (I’d imagine it would be good enough for most scenarios locally)?

Anshuman, I just upvoted your feature request.

Feartec, while I too was looking forward for a local solution and I too use sqlite3 for pretty much all my Corona stuff, I wasn’t aware of Cloudant. Thanks for posting.
