It's unusable on the ipad for me because of the most important feature of checkvist - fast typing.

Basic typing
enter - add new item, cursor focus on next line
tab - indent
moving things around

When bluetooth keyboard is connected
command arrow to move things around

Its not much of an offline option, but Checkvist via the iPads' browser is phenomenal. I realize smooth mobile browser use is a bit of a low bar these days, but Checkvist is still leaps and bounds above other similar web-based systems I've tried.

P.S.: A native app would be fabulous! just had to throw out kudos for well-done work in making the browser version work so well. ;)

@Jonathan, thanks for the information about bluetooth keyboard with iPad. We'll have a look as soon as we'll get a chance to try it. May be, you'll create a separate request in uservoice for that?

In Safari on iPad I cannot use the keyboard shortcuts for navigation when using a bluetooth keyboard. This is frustrating, as one of the main reasons I wanted a keyboard for my iPad 2 was for working on my checkvists faster :-P

@Zeff, @Hospodi, please add your votes to the iPhone/Android request at http://checkvist.uservoice.com/forums/2121-general/suggestions/42535-iphone-android-version

I'd gladly pay for an iPhone version ...

I will pay for an iPhone app. Check out the "goTasks" app for a model of useful iPhone app. Ajax i be that hard really is it?

Need a droid application badly. Your competition beckons me without it.

@Keith, I don't think CarbonFin would want to add this feature to their Outliner app :)

Outliner is a great iPad / iPhone outlining app, it would be great if Outliner could talk to the checkvist API.
