Improve Webapp Accuracy and Publishing

My webapp is already live but the first priority is to sharpen its accuracy by rooting out the logic errors that slip past my current logging / debugging setup. I want clean, reliable output and graceful recovery when things do go wrong.

Here’s what I need next:
• Pinpoint and fix the logic-level bugs that are affecting calculations and AI responses.
• Design a more robust error-handling flow so I’m not relying solely on log files. Feel free to introduce custom handlers or strategic try-catch blocks where they add clear value.
• Audit the AI component for smarter token usage; every token saved improves speed and cost.
• Once stability is proven, advise on the roadmap for new features and package the project for an eventual Google Play launch.

You’ll have access to the existing codebase, logs, and any supporting docs. Clear commit history, concise comments, and a short hand-off note for each fix will be the acceptance criteria. If you have experience turning webapps into Play-ready builds, mention that because it will become phase two soon after the logic clean-up is complete.
