WhenWas

Stay on top of the things that don't fit a calendar—home care, pets, routines, and shared chores. Check in once and always know when it was last done.

When did you last water the plants, change the air filter, or call Mom? WhenWas remembers for you — tap once to check in, and always know how long it's been.

WhenWas is the simple "time since" tracker for all the little things that don't fit on a calendar. No due dates, no guilt, no streaks to break. Just a clean list of the things you care about and exactly how long it's been since you last did them.

NEW — SHARE ACTIVITIES WITH FAMILY & FRIENDS Now you can track things together. Invite anyone to a shared activity — everyone sees the latest check-in and anyone can reset it, kept in sync in real time across all devices. Perfect for households: who fed the dog, when the litter box was cleaned, when the sheets were changed. No more "did you already do it?" texts.

PERFECT FOR TRACKING • Home care — watering plants, changing filters, cleaning gutters • Pets — flea treatment, grooming, vet visits, feeding • Health — haircuts, dentist visits, contact lens changes, medication refills • Relationships — calling parents, date nights, catching up with friends • Car & maintenance — oil changes, tire rotation, battery swaps • Anything else you keep asking yourself "when did I last...?"

HOW IT WORKS

1. Add an activity once
2. Tap to check in whenever you do it
3. See exactly how many days, weeks, or months it's been

Every check-in is saved to a timeline, so you can look back at your full history — with optional notes for context ("used the heavy-duty filter this time").
