We see your need. Please give us some time as first of all we are aimed to spruce up web app (make it perfect) and only after that switch to iPad and iPhone applications.

Have been evaluating Everhour and Toggl. Prefer the hashtag system and reporting of Everhour - organic and easy like Workflowy. Lack of mobile option may be a deal breaker tho :P
