Filter Reminder

Filter Reminder keeps every household filter and its service schedule in one organized place. Track filters for water systems, air conditioners, vacuum cleaners, range hoods, and air purifiers. Save the model, installation location, last replacement date, service interval, and a photo of the filter or package.

The app calculates the next replacement date automatically and shows a clear status: fresh, due soon, or overdue. Local notifications alert you before service is due and can continue reminding you when a filter is overdue.

Features:
• upcoming replacement schedule;
• search by name, model, or installation location;
• category and status filters;
• filter or package photo;
• quick replacement logging;
• complete service history;
• spare filter, supplier, and recent price tracking;
• notification controls for individual filters;
• JSON backup, CSV export, import, and system sharing;
• system, light, and dark themes.

Filter Reminder works without an account or internet connection. Your records stay on your device, and you control when to create or share a backup through Android system tools.
