Choose Forgot password? on the app’s sign-in screen, or request a reset email here. Open the newest email from noreply@auth.cardiaworld.com, choose a new password, then return to the app and sign in. Check Spam or Junk if the email does not appear.

Choose Sign in with that email. If you don’t remember the password, reset it using the link above. Your original account and progress stay with you.

Record at least 15 minutes of cardio in one day. You can choose a goal from 15 to 480 minutes, including a custom whole-number goal. Fifteen minutes is the minimum needed to advance construction.

Yes. Separate sessions recorded on the same day are combined toward your daily total.

Your device stores activity, settings, and world progress. When you sign in, a private account backup can restore your world on another device. Friends only see the world details permitted by your privacy choices.

Yes, if you grant permission on a compatible iPhone. Steps and recorded workouts can update your world. You can also log cardio manually.

Open Settings in the app and choose a preset or enter a custom daily goal from 15 to 480 minutes.

Open Settings and select Erase all local data to reset this device’s world and its signed-in account backup. To delete the account and associated server records, use Delete my account in Friends. These are separate actions.

Set your cardio days in the weekly routine editor. Your other days are protected rest days from when you save the routine. Earlier activity is preserved. Your reminders can follow the days and times you choose.

Open Progress → World journal, or save a view from World. The journal keeps the latest 36 captured moments for the signed-in account. In the current App Store app, these images stay on this device and are separate from the world-progress backup.

Preview monthly keepsakes for free. With Pro, qualifying cardio days in the current month can unlock eight rewards at days 1, 3, 5, 8, 12, 16, 20 and 24. Dates need not be consecutive. Display three owned pieces; earned pieces remain yours if Pro ends. Pro also adds premium styles, customization, advanced statistics, Cardio Battles and mission hosting. Invited free friends can join Co-op Cardio Missions.

Your mayor writes inside the app when missed planned cardio days affect your world and when you return to begin restoring it. Protected rest days do not count as missed days. Read the letter in Inbox; reading never changes your activity or world progress.

These are available in Cardia World 1.1.29. Update from the App Store, then open World activities or Progress → World journal. Explore the latest features.

Cardia World adds image previews, date groups, sorting, filters and selection controls in Progress → World journal. Save one image or several images directly to Photos, or confirm deletion of selected entries. Entries expire after 30 days when you open the app; the limit of 36 recent entries still applies. Existing entries receive a fresh 30-day age window with the update. Saved Photos and earned world progress are unaffected. Backup follows deletion and expiry when it syncs online.

Completing four different qualifying cardio days unlocks Elect your Mayor. Name your mayor, rename them later, and see the name in future letters. Older letters retain their original signatures.

Skies unlock on cardio day three and Paths on day six. Later abilities remain previews until earned. The app uses qualifying cardio days consistently, including restoration days, and refreshes subscription access when Settings opens. If needed, use Refresh Pro access or Restore Purchases while signed into the Cardia World account used for the subscription.

Open Cardia World’s App Store page and tap Update when offered. Check for updates opens that page for full app releases, and an Open App Store button is always available. Downloaded content improvements use a separate restart option. Private beta builds are updated through TestFlight. The app cannot press Apple’s Update button for you.

Open your friend’s invitation link and accept during your account’s first seven days. Complete three different qualifying cardio days after acceptance to earn a Friendship Garden for both of you. Sending a link alone does not earn the garden or automatically add a friendship.

No. Creating the first rotating journal video earns a Showcase Pavilion. Sharing to a Story or anywhere else is optional. Creating a video in a later week can add a banner, up to three appearances. The caption uses the cardio-minute total saved with that moment; older image-only captures do not invent a historical rotating view.

Journal backup is off until you turn it on in World activities. It keeps up to 36 recent captures in your private account, separately from ordinary world-progress backup. Expiry and deletions sync when online. You can restore captures or turn backup off and delete the cloud journal. The optional widget uses a saved world view and game summary; enable it in the app and add a small or medium widget through your device’s Home Screen controls.

Use Settings → Send feedback in the app, or email us with the screen you were viewing, what you expected, what happened, and your app and system versions. Feedback lets you choose whether to include device details or a world image before reviewing the email.

No. Cardia World is a motivational world-building game and not a medical device. It does not diagnose, monitor, or treat health conditions.
