Filter Log is the household filter tracker that isn't locked to a brand. Record every filter in your home — HVAC, refrigerator, range hood, vacuum, humidifier, water pitcher, car cabin — set the replacement cadence, and get a local reminder the day each one is due. Every filter has a photo, brand, size, and where-to-buy link. Filter Log also tracks how many spares you have on hand, so you know to reorder before you're standing in front of an empty vent on a Sunday morning. No smart hardware required. No account to sign up for. Nothing leaves your device. Features: • Track every household filter in one list — HVAC, fridge, range hood, vacuum, humidifier, water pitcher, car cabin • Per-filter replacement cadence in days, with sensible defaults per category • Local notifications when a filter is due — no cloud, no account • Spares-on-hand inventory with "running low" alerts • Reorder link per filter — tap to open your preferred store • Mark-changed action auto-decrements inventory and reschedules the next reminder • Overdue and Due Soon sections so nothing slips through • Universal app — iPhone and iPad, optimized for iOS 17 Filter Log Pro: • Unlimited filters (free plan covers your first 3) • Low-inventory alerts • Home Screen widgets showing what's due next • Household sharing via iCloud — your family sees the same list • Barcode scan to auto-fill brand and size Unlock full access with Filter Log Pro for £9.99 per year.

Verdict
The clearest difference is in-app purchases: Date Stamper at none against FilterLog's 1. Date Stamper also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
