FilterDue — Filter Reminders

Dirty filters cost energy, shorten equipment life, and hurt air quality — but nobody remembers the date they last changed one. FilterDue tracks every filter in your home, brand-independent: HVAC, water, fridge, and air purifier. • Color-coded countdown for every filter (good / due soon / overdue) • Suggested replacement intervals per filter type — fully adjustable • "Replaced today" one-tap reset, plus edit & history • Reminders before a filter goes overdue FilterDue Plus — optional auto-renewable subscription: $1.99 per month or $9.99 per year. Unlimited filters, home screen widget, purchase-link reminders. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; manage or cancel it anytime in your App Store account settings.
