This is just a random thought, but I think you could avoid using some of the features mentioned by other users (e.g. deadlines, priorities) by limiting the scope of the list to weekly tasks. Presumably this would limit the length of the lists, which in turn would eliminate the need for fancy features that might bloat the app. If people want those other features (i.e. they are using the lists for serious planning and project management) you could then charge. Just my 2 cents.
