App Store 1.4 rejection: Physical harm

Apple is questioning whether following your app could hurt someone. Guideline 1.4 brings together medical claims, dosage tools, substance-related features, road-safety information, and dangerous activities. The specific subrule tells you which problem to address.

Trace the advice into a real action

Look at what a person is encouraged to do after reading a result or completing a challenge. Check generated advice, rewards, notifications, and instructions from third-party content. We’d review the action itself before revising a disclaimer.

For medical measurements, start with 1.4.1. Dosage calculators have separate provider or approval requirements under 1.4.2. Other children of this rule cover substances, checkpoints, and dangerous activities.

Remove the source of the risk

Change the feature or instruction identified in the review. If safety depends on qualified oversight or valid documentation, supply the relevant evidence and keep the app within what it supports. A warning can’t make an unsafe feature reliable.

Test the changed behavior with safe test cases. Explain to Apple what the person now sees and can do, and identify the build containing the correction.
