I'm building MediDue, a planned English-language iPhone app for home medicine inventory. The idea starts with a practical question: could a simple list make it easier to check what is at home, where it is stored, how much is left, and which expiry dates need a closer look?

I currently have a browser prototype. It records medicine names, expiry dates, quantities and storage locations, with views for inventory and expiry or low-stock tasks. Users check the information they enter. The iPhone app is still in development, with no public download available yet.

The design problem I'm working through is the effort needed to keep those records useful. Entering a quantity once is straightforward; keeping it accurate as things get used or moved is harder. Adding more fields might make the first record more complete while also making every later update more work. I don't have user research results to settle that trade-off yet.

I'd like to hear from people who have kept a household inventory, or built a tool people use only occasionally:
