When did you last get a haircut? See your dentist? Change your bed sheets?
Probably "a while ago." You know roughly — but without a record, it's just a vague unease living in the back of your head.
Who changed the AC filter last? Took the dog to the vet? Watered the plants?
If you're not sure — your partner probably isn't either.
How long until your holiday? Payday? The trip you're both counting down to?
You know the dates. You just haven't counted the days.
When holds all of it — and shares it.
Add the things you do occasionally but never schedule. Tap once when you do them. When shows you exactly how long it's been — beautifully, at a glance.
— DAYS SINCE —
Track anything you do occasionally: health, home, vehicle, body, finances. The list sorts by most overdue first. The featured card surfaces the thing that's drifted furthest. One swipe logs it and resets the clock to zero.
— DAYS UNTIL —
Set a date and watch the countdown. A trip, an appointment, a deadline — When holds both directions. One word. Two modes.
— SPACES, SHARED —
Organise your items into Spaces — Home, Car, Health, whatever fits your life. Then share a Space with a partner, housemate, or anyone tracking the same things.
Everyone sees the same items in real time. Anyone can log. When something's done, it's done for both of you — no more "I thought you handled it." Nothing slips through the gap.
— REMINDERS —
Set a threshold on anything that tends to drift — and When will tap your shoulder when it's been too long. Gentle nudges, no alarm tones. Just a quiet signal that it's time.
— DESIGNED TO BE KEPT —
When looks better than anything else in this category. Beautiful tools get used. Used tools become habits. Habits make the app worth keeping on your home screen.
— HOW IT WORKS —
Add a thing (emoji, name, Space)
Tap once when you do it
Come back whenever you wonder
Share a Space to track together
Because "sometime last year, I think" isn't good enough — for either of you.
