Your first day in Cardia World.
- Create an account and choose your world. Your account lets you save and restore progress. Start with a free style and select a cardio goal.
- Record cardio minutes. Enter a session manually, or connect optional Apple Health on a compatible iPhone for supported workout imports. At least 15 recorded minutes in a day qualifies for construction.
- Open World. Explore the place your activity is building. Construction and milestones accumulate over time, from an early clearing toward larger settlements and a planet.
Let Apple Health bring your workouts in.
Connect Apple Health in Cardia World and allow access to Workouts and Steps. Supported cardio workouts saved in Apple Health, including walks, runs, and bike rides, can import automatically and contribute cardio minutes and build points.
Record your workout with Apple Watch or a compatible app that saves workouts to Apple Health. Then open Cardia World to refresh your progress, or use Settings → Sync activity now. Syncing may take time; if a workout does not appear, check Health permissions and confirm the session is saved as a workout in Apple Health.
At least 15 recorded cardio minutes in a day qualifies for construction. Daily step totals support world vitality, and do not automatically become cardio build points. Apple Health is optional; manual cardio logging remains available.
What you can do for free.
Build a world, log cardio, follow your progress, and connect with friends. The free starting styles are Cozy Heritage, Modern Grove, and Future Bloom. You can search for a friend’s username in Friends, send a request, and connect after they accept.
Optional Cardia World Pro adds Neo City, Solar Garden and Zen Valley, customization, monthly collections, advanced statistics, Cardio Battles and Co-op Cardio Mission hosting. Invited free friends can join missions. You can start building without a subscription.
Learn with your Mayor and explore Pro.
After this update is released, open Home → Heart lessons for the Mayor’s free cardiovascular lessons and quizzes. There are 24 lessons and 72 questions, unlocked through qualifying cardio days. Your first lesson opens on your first cardio day, before the day-four Mayor election. After that election you can name your human or pet Mayor and personalize their clothing colors and accessories.
In World → Customize, the shiny gold controls lead to three free Pro look previews. Previewing changes no saved progress. Applying earned premium choices requires Pro.
Open Home, Settings or Progress → Wellness for 16 guides across movement, sleep, nutrition and stress. Three samples are free; the full library and rotating daily read are Pro. Your Mayor’s lessons and quizzes remain free. Explore every addition in 1.1.36.
Use the app’s top-of-page shortcuts to jump to features. In Friends, send repair encouragement when a friend’s world needs care, or share an Apple Music playlist link.
Keep your progress, and make room for rest.
Choose your planned cardio days in your weekly routine. Other days become protected rest days from the day you save the routine. In Progress → World journal, revisit up to 36 real captured views of your world. Save a new view from World and share an image only when you choose.
For a clearer activity check, open How did this count? to see credited minutes and days. In Settings, you can adjust automatic reward recaps, turn on Battery-saving world or use Send feedback.
Give your world a story of its own.
Mail & Mystery opens after three qualifying cardio days with a different 24-chapter story for each style. Choose your replies, discover research from cardio day five, and earn and send gifts. Your mayor also writes in the app when your world needs care and when recovery begins.
Monthly collections offer eight keepsakes to preview. Pro members can earn pieces with qualifying cardio days during the month and display three owned pieces at a time. Dates do not need to be consecutive, and earned pieces remain yours after Pro ends.
Rotating videos, invitations and a creative terrace.
Version 1.1.29 adds short rotating journal videos with saved cardio minutes, one-link invitations with Friendship Garden rewards, a choice of small buildings, named residents and a weekly community build.
It also adds small and medium Home Screen widgets, optional private backup of the latest 36 journal captures, and Pro Design Studio with nine terrace plots and three saved layouts. Read the full feature and reward details.
Understand what the preview shows.
The video introduces the app’s world-building and social experience. Larger cities and planets represent progress earned over repeated activity. They are not all unlocked by a single workout.
