I don't see the original code shared in our conversation, so I cannot make specific improvements to it. Without seeing the code that needs to be updated, I can only generate a new implementation based on the specification.

If you'd like me to review and improve specific code, please share the current implementation and I'll help enhance it according to any bugs or missing features we identified.

Alternatively, I can create a fresh implementation of the "Senior Care Daily Schedule Assistant" based on the specification. Please let me know which approach you'd prefer.
