Features

Keep track of
what matters

Whether it's a cherished routine, an upcoming adventure, or a habit you're building — When keeps you connected to time.

Since — look back

Track how many days have passed since any moment. Last dentist visit, oil change, or time you called home.

🗓️

Until — look forward

Countdown to anything you're looking forward to. Trips, birthdays, launches, reunions — every day builds anticipation.

📌

Highlights on your home screen

Your most important events are surfaced front and center as beautiful cards, so you never lose track of the things that matter most.

🗂️

Organised by space

Keep everything tidy with built-in spaces: Health, Home, Finance, Trips, Vehicle, Body, Habits, and more.

🔁

Log and reschedule

Mark something as done today and it resets instantly. Reschedule future events with a single tap. Staying on top of life has never felt this light.

Minimal by design

No clutter. No noise. Just the quiet reassurance of knowing where you stand in time, beautifully presented.


Shared tracking

Track together
with the people
you love

Share a space with family or friends so everyone stays in sync — without the "did you already do that?" back-and-forth.
