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.
