Count days. Grow together.

A little friend for every day.

Calculate dates, age, weekdays, and countdowns while an original cat or dog companion eats, grows, earns achievements, and welcomes a family—without getting in the way of the tools.

Useful date tools

Date difference, add or subtract, full age, weekday count, D-Day, and yearly events.

A calm virtual family

Use a tool, serve a meal, and grow. Pets roam only in their room and widgets, never over a calculation.

Private restoration

Works locally without an account. Personal iCloud can privately restore your pet and events after reinstalling.

Achievements

Nine clear milestones for calculations, care, events, growth, and a three-pet family.

Home & Lock widgets

See your real illustrated pet and nearest countdown at a glance.

No ads or tracking

No developer account, analytics SDK, behavior tracking, or chance-based paid reward.
