Lead Follow Up Tracker App Builder

Build a simple lead follow-up tracker with Claude Code. It opens on who to follow up today: overdue, due today, next 7 days. One tap opens WhatsApp, email or a call with your message template filled in; then log the follow-up and pick the next date. Set your own stages, lead sources, currency and templates. Pipeline view, search, CSV import/export and JSON backup. One offline HTML file; data stays in your browser. No login, server or API keys.
