- (Obviously from the above) There's no contacts list.
- There is no internal (per project) calendar, or external calendar (personal) integration.
- BUG: Date picker widget doesn't handle font sizes being different than expected (i.e. it doesn't scale).
- There is no hierarchy of tasks, hence there's no way to map dependencies.
- There's no 'length' (of time) field.
- Per-item check boxes do nothing?

There are also quite a number of competing task/project management apps for google domains/GAE that you might want to look over.
EDIT: Sorry. I forgot to even mention the positive things. Seems I need sleep... ;)
- The design is clean and looks good.
- It was very intuitive. Bravo. Just looking at it was enough to grasp what it does.
- It seems like a really good start but you're entering a very crowded space.
