Filterness — Never Miss a Filter Change Again
A simple, offline tracker for every filter in your home, car, and appliances. One screen. One list. One tap to mark as done.
TRACK EVERY FILTER
Add any filter you need to keep track of:
- HVAC / central heating and cooling
- Kitchen hood / range hood grease filters
- Water filter (whole-house, under-sink, reverse osmosis)
- Water jug (Brita, ZeroWater, and similar)
- Car cabin air filter
- Car engine air filter
- Air purifier
- Dehumidifier
- Dryer lint and exhaust filters
- Vacuum (HEPA, pre-motor)
- Custom — anything else with a replacement interval
HOW IT WORKS
1. Add a filter — pick a type, name it, set the interval
2. See your list — one sorted screen shows what is due soonest
3. Tap "Replaced" — one tap resets the timer when you swap a filter
4. Get reminded — notifications 3 days before and on the due date
No dashboards. No charts. No complexity. Just a clean list sorted by urgency.
SMART REMINDERS
Filterness sends you two local notifications per filter:
- 3 days before it is due
- On the due date
Both arrive at 9:00 AM. Never forget a filter change again.
100% OFFLINE AND PRIVATE
Filterness was built with privacy as a foundation, not an afterthought:
- No internet connection required — works anywhere
- No user accounts or sign-ups
- No data ever leaves your device
- No third-party analytics or tracking
- Your filter data stays on your phone — only you can see it
ONE PRICE. NO SUBSCRIPTIONS.
Filterness is a single purchase. No subscriptions. No in-app purchases. No ads. Pay once and track every filter you own.
