Frequently Asked Questions
Do I need Apple Watch?
Yes. Recording workouts requires Apple Watch Series 10 or later with watchOS 11 or later. The iPhone companion requires iOS 18 or later and provides metrics, settings and workout history.
Can I work out without my iPhone nearby?
Yes. Start, pause, resume and end the session on Watch. Recording continues without an iPhone connection; completed workouts transfer when the devices can communicate again.
Why are heart rate or calories missing?
Metrics depend on available data and Health permissions. Check your Health and JoJump settings. A missing value does not necessarily mean that access was denied.
Can I correct the jump count?
You can edit the final count from the session summary on iPhone. JoJump also preserves the original detected count.
Where is my data, and how do I delete it?
History is stored locally on iPhone and Watch. JoJump lets you delete one session or all app history. Workouts already saved in Health must be managed separately in Health. You can explicitly export your data as JSON or CSV.
Do I need a purchase or an account?
No. All features are available without an account or purchases. The three optional one-time tips do not unlock functionality.
How do photos and sharing work?
The optional camera creates an image with your workout summary. Saving to Photos and sharing happen only at your request. Images may include fitness metrics: review them before sharing.
