Meet Nubi: a round lavender plush companion with tiny feet and a friendly smile.
A little Nubi. A little more you.

Your wrist. Your perspective.

Notice a moment.
Make it a little more interesting.

01 / REFLECT

Follow your pulse.

Review available heart-rate readings alongside the moments you mark. When there’s enough recent context, see how your session compares.

02 / PLAY

Take the Hot Seat.

Play five questions from three decks, or tell a story and let a friend guess truth or bluff. Share a Nubi invitation when you’re ready. Sensors are optional; player reveals are your own choices.

03 / LOOK BACK

Give it some context.

Review the last 15 minutes of available readings, or start fresh for a guest. Missing readings stay missing. No made-up scores.

Make it yours

Little companion.
Your kind of style.

Choose Nubi’s body color, outfit, hairstyle, makeup, and accessory. Add glasses or a sparkle, then say hello to five expressive faces. These personal touches are included, with no extra purchase.

Keep the classic look, dress Nubi for a role, or try an included seasonal outfit. Nubi’s expressions follow your taps and completed turns; they never judge your pulse or decide whether you lied.
