I do tend to agree, unless you reach large numbers of users and get around a 2% - 5% conversion rate to paid subscriptions I don't think freemium is good.
However, with it being a task management app it isn't impossible that it will break this kind of number. Though with the competition it may be a bit of a long shot.
I think the key question is whether they will reach that level of users...I guess not. To reach 10 million + users which is the only way I see to make this worthwhile would take a massive amount of effort in a crowded marketplace like this, it isn't likely at all.
So with that being said, going freemium is probably the death-knell for the product.
Thanks for the feedback I appreciate. While it is beta we are not charging and what you're using now will remain free but we will be looking at expansion, for more information you can take a look here.
