Some things are too important to forget — and too infrequent to remember. When did you last change the AC filter? When does the car registration renew? Is it too late to return those headphones? Window is the place for the things that only come up once in a while. Tell Window once. It remembers when. — DO IT. MARK IT DONE. FORGET ABOUT IT. — Changed the water filter? One tap. Window records the date, works out when it's due next, and reminds you before it matters again. — KNOW WHEN YOU LAST DID IT — Every item keeps a simple history of each time you actually did it. Window doesn't just remind you — it remembers. — WHAT NEEDS ATTENTION, FIRST — Home is ordered by what matters now: what's overdue or coming due, then what's coming up, then everything later. "13 days left" instead of a date you have to work out. — REPEATING THINGS AND ONE-TIME DATES — Every 60 days, every 6 months, every year — or a single date, like a return window, a free trial, or a warranty. You never choose a mode; just answer "when should this come back?" — ADD SOMETHING IN SECONDS — Start from suggestions for the home, the car, yourself, your pets and your paperwork: AC filter, water filter, smoke detector batteries, oil change, tire rotation, registration, dentist, contact lenses, flea and tick treatment, returns, renewals, warranties. — CALM REMINDERS — A heads-up in the morning before something is due — a few days for a filter, a month for a registration — and again on the day. No streaks, no nagging, no badges demanding attention. — WIDGETS — See what's coming up on your Home Screen and Lock Screen. — PRIVATE BY DESIGN — No account. No sign-in. Everything stays on your iPhone. — WINDOW+ — Free for up to 5 active items. One purchase unlocks unlimited items and custom icons. Pay once, keep it forever.
