Current work in progress for the offline HTML5 hybrid app, please try it: https://checkvist.com/auth/mobile
We also have a separate feature pool for it:
I know I may be in the minority here, but an offline capable version of a checkvist iphone/ipod touch app would be awesome for me. I have an IPod Touch, so being able to manipulate a cached version of my lists, then letting them sync up when I get around a Wifi connection would be great. Just a thought
Going to the local store to get an iPhone today... We need a device to test checkvist on and to provide you with iPhone version.

It's a must today!
I really need it to use Checkvist all the time.
