Still no android app? Guys, come on, this is ridiculous!
CheckVist is so great, but the lack of a mobile app+widget to keep track of todays activities is seriously hindering in its use!
If you think people are going to check their todo's in a mobile browser on a phone, you're crazy - is so unconvenient and slow...
At least a basic version with only basic task editing\creating capabilities, but good filtering and a widget to see today's tasks should've been out there already.
