About AquaTrack

AquaTrack is a free reminder app for the filters and water-treatment parts in your home. You tell it what you have installed, when it was last changed, and how long it lasts. From then on it keeps the schedule for you, so a cartridge never quietly runs months past its prime. Each item keeps its own timeline, replacement history, part number and how many spares sit in the cupboard, and multi-stage systems such as reverse osmosis get a separate schedule for every stage.

Reminders arrive by email and, in the mobile app, as push notifications. You decide how early the first nudge comes, how often an overdue item keeps asking, and when it is time to reorder before you run out. Nothing is shared, nothing is sold, there are no ads, and no payment details are ever requested.

It is built for anyone who owns a water filter and would rather not think about it: True Filters customers who scanned the QR code on a cartridge box, households with an under-sink system, a whole-house sediment filter, or a water softener that needs salt. If you have ever wondered “when did I last change this?”, AquaTrack is for you.

AquaTrack is built and maintained by the True Filters team, the same people who make the replacement cartridges it reminds you about. We keep the app simple on purpose: fast to set up, quiet unless something needs doing, and honest about what it stores.
