An iPhone or iPad running iOS 15.6 or later. Jump counting works with both the front and rear cameras; for the best AI recognition frame rate, we recommend iPhone 12 or newer. Older devices may feel slightly less responsive. Lock Screen widgets require iOS 16 or later, and in-app code redemption requires iOS 16.3 or later.
Counting works by watching your body movement, so the camera is essential — denying access will disable the core check-in feature. Frames are processed on the phone and never uploaded. If you denied it earlier, head to iOS Settings → Privacy & Security → Camera → HappyJump and turn it back on.
About 1.5–2.5 meters away, with the camera at the level of the jumper's upper body. Use even lighting (natural or main indoor lighting), avoid backlight. Wearing clothes that contrast with the background helps recognition stability.
Yes. HappyJump supports both iPhone and iPad with the exact same features; jump counting works with the front and rear cameras — prop the iPad up securely and step into the frame. With iCloud sync (Pro) enabled, your records, achievements, and profiles sync automatically between iPhone and iPad.
Counting is AI-based and affected by lighting, angle, clothing, and motion—1% error is normal. Check that:
If error exceeds 5%, please email us with a description of your setup.
No action needed. When the rest countdown ends, a beat tone plays automatically and the next segment starts. To stop training mid-session, tap the red stop button.
On the Fitness Goals page, set a one-minute jump-rope goal for yourself or a family member: primary-school ages can use the built-in reference standard (the matching tier is filled in automatically by grade and gender), while everyone else simply sets a custom target count. After a 60-second session, the results page immediately shows your level and how far you are from your goal; the score-card level badge, weekly / monthly summaries, and the Home Screen widget reflect your goal progress too.
Basic goal evaluation is free; the goal progress chart and multiple goals are Pro features.
The built-in reference is based on the one-minute jump-rope scoring table in China's National Student Physical Fitness Standard (2014 revision), for reference only — always follow what your school or local education authority publishes. You can also skip the built-in reference entirely and set a fully custom target count.
Go to iOS Settings → Apple ID → iCloud → Apps using iCloud, and make sure HappyJump is toggled on. If the toggle is on but the message persists, restart the app or your device.
No. Codes expire after 48 hours, primarily to prevent stale codes circulating in chats. Generate a new one with another quick session.
Locally on your device: free version keeps the most recent 7 days / 5 sessions; Pro keeps unlimited. On Apple's CloudKit servers, records are auto-deleted 30 days after challenge completion.
In a custom challenge, the creator sets the jump seconds, rest seconds, and number of rounds (or imports a custom workout they've already saved). The other player then jumps once with exactly the same parameters, and the higher combined total wins. Before accepting, you'll see the full rules: what's being compared, how the winner is decided, and when it expires.
Creating a custom challenge, Cadence PK, Training PK, or Endurance challenge requires Pro; timed-jump challenges are free to create. Joining any challenge via invite code or QR is always free. Invite codes are the same 6 characters, valid for 48 hours.
Under Settings → Appearance you can choose Follow System / Light / Dark. Dark Mode is completely free, and everything is adapted — from the launch screen and app icon to every page inside the app. The same page offers 5 theme colors: Sky Blue is the free default, while Forest Green / Violet / Coral Pink / Ocean Teal are Pro entitlements.
Appearance and theme color are saved per member: switch profiles and the app switches to that member's chosen look, so no one affects anyone else.
Widgets read a snapshot the app writes locally on your device, and they update automatically after a check-in or a member switch. If a widget seems stale, try these in order:
Widget refresh timing is scheduled by iOS itself, so an occasional delay of a few minutes is normal. Lock Screen widgets require iOS 16 or later.
Open iOS Settings → Apple ID → Subscriptions, find "HappyJump Pro", and tap "Cancel Subscription". Pro features remain available until the end of the current billing period.
Note: Deleting the app does not automatically cancel a subscription.
App Store in-app purchase refunds are handled by Apple. Visit reportaproblem.apple.com, sign in with your Apple ID, find the order, and submit a request. We're unable to issue refunds directly.
Sign in on the new device with the same Apple ID, open HappyJump → Settings → Membership, and tap "Restore Purchases". Subscriptions are tied to your Apple ID, not your device.
All three products support Apple Family Sharing. Once enabled, up to 5 family members can share the Pro entitlement. Configure Family Sharing in iOS Settings → Family.
Got a gift code? Tap "Redeem Code" at the bottom of the paywall or under Settings → Membership. The official App Store redemption sheet appears — enter the code to unlock the corresponding Pro entitlement, identical in every way to a regular purchase.
In-app redemption requires iOS 16.3 or later. On earlier versions, the app will guide you to the App Store instead: tap your profile picture in the top-right corner → "Redeem Gift Card or Code" — redemption works just the same there.
No. Both real-time and end-of-session watermark passes happen on your device. When you tap "Save to Photos", the video is written to your Photo Library. We never access or upload video content.
In-app: Settings → Data Management offers options to clear all records or all achievements for the current user. Deleting an entire profile cascades cleanup across records, achievements, reminders, settings, and challenge data. Uninstalling the app removes all local data. If you enabled iCloud sync, also delete HappyJump's iCloud data via iOS Settings → Apple ID → iCloud → Manage Account Storage.
None. We don't integrate any third-party analytics, advertising, push, or social-sharing SDKs. See the Privacy Policy for details.
Include your app version and a description. We’ll respond within 1–3 business days.
