Client CRM & Follow-Up Tracker (Working App)

A real working web app (single HTML file, no install, runs offline in any browser) to track clients and follow-ups. Add clients with contact, project, status, last contact date, and next follow-up date. Overdue follow-ups are highlighted in red so nothing slips through the cracks. Sort by follow-up date, export/import your data as JSON anytime - your data stays local, never uploaded anywhere. Built for freelancers who lose revenue by forgetting to follow up with past clients.
