What's New in Remember the Filter
1.1
October 13, 2026
Built for iPhone Duo. • Side by side: open your Duo to see your filter list and the selected filter's details at the same time — the divider even lines up with the fold. • Tabletop Change mode: stand your Duo half-folded and the top half shows exactly what to install — size, MERV rating and airflow direction — big enough to read from the floor. The bottom half gives you big Mark Changed, Reorder and Snooze buttons for dusty hands. • Reorder beside your list: the store opens next to your filters instead of covering them, with the exact size and MERV shown above it. • Closed or open, everything fits: on the outer screen, controls move to the side rail automatically. • For businesses: order straight from your pull list — each size opens in the store beside the list, quantity pre-filled, so you can work through the whole order without losing your place. New for every iPhone — filters on hand: • Bought a case? Track how many filters you have left. Each time you mark a filter changed, the count goes down — 12, 11, 10… • Get a heads-up when you're running low, with one tap to reorder your exact size. • Add a case when your order arrives. • For businesses: your pull list now shows what's on hand and how many cases to order. Fixes and improvements: • Fixed a crash when tapping a filter reminder notification. • Tapping a reminder now opens that filter directly, even when the app wasn't already running. • Improved layouts at larger text sizes. • Confirmation pop-ups now point to the button you tapped.
