FilterSlate
A USD 0.99 paid App Store download for reliable filter upkeep — no account, subscription, in-app purchase, ads, tracking, or required internet connection.
FilterSlate
Keep household filter schedules, part specifications, immutable replacement history, and spare inventory together in one private offline ledger.
Know exactly what is due
Organize filters by room and appliance, save part numbers and specifications, and see overdue, upcoming, and later replacements from one clear dashboard.
Preserve every replacement and spare
Replacement and inventory changes are immutable events. Corrections use explicit reversals, so current stock and the complete history remain auditable.
Keep your records private and portable
Data and selected photos stay on your device. The USD 0.99 download includes local reminders, text and CSV exports, and checksum-verified backup preview, merge, and restore.
