Filter Care

Filter Care is a simple, offline service log for RO and water-filter technicians. No account, no sign-up, and no internet connection are required — open the app and start managing your service calls right away.

Register the units you look after, log every visit (installation, filter change, repair, or checkup) with the parts replaced and the charge, and always know which units are due soon or overdue. Keep customer details handy and review your workload and earnings at a glance.

What you can do:
- Register RO / water-filter units per customer with install date and notes.
- Log services with type, parts replaced, charge, amount paid, and next-due date.
- See each unit's status — Up to date, Due soon, or Overdue.
- Browse the full service history and open any visit for detail.
- Keep a customer list and review their units and recent services.
- Review reports — services and amount billed over the last 7 days, plus a by-type breakdown.

Everything stays on your device. The app collects no personal data, shows no ads, and works fully offline. Amounts you enter are simple typed records — there are no in-app payments.
