Our Take

Apple is rejecting your app because it makes health measurement claims that can't be validated, or it could provide inaccurate medical data. Apps claiming to measure blood pressure, blood glucose, blood oxygen levels, body temperature, or take X-rays using only the phone's sensors are explicitly not permitted. This rejection applies broadly to any health, fitness, or medical app that makes accuracy claims without disclosing methodology, or that could mislead users into making medical decisions based on inaccurate data. Even legitimate health apps need to include 'consult your doctor' disclaimers. If your medical app has received regulatory clearance (FDA 510(k), CE marking, etc.), you can submit documentation to support its claims. But for apps using only the phone's built-in sensors to make medical measurements, there's no path to approval.

Resolution Guide

Remove impossible measurement claims

If your app claims to measure BP, blood glucose, or blood oxygen using only the phone camera/sensors without approved hardware, remove these features entirely. There is no workaround.

Add methodology disclosure

For legitimate health measurements (heart rate via camera, step counting via accelerometer), clearly disclose the methodology and accuracy limitations.

Add medical disclaimers

Include prominent disclaimers: 'This app is not a medical device,' 'Consult your healthcare provider before making medical decisions,' 'Results are estimates and should not replace professional medical advice.'

Submit regulatory clearance

If your app uses approved external hardware (Bluetooth blood pressure cuff, glucose monitor, pulse oximeter), submit the regulatory clearance documentation in the Review Notes.

Separate wellness from medical claims

Frame features as wellness tracking ('track your fitness trends') rather than medical measurement ('measure your blood pressure').

Prevention

Never claim medical measurement accuracy without regulatory clearance

Always include 'consult your doctor' disclaimers in health apps

Clearly distinguish between wellness tracking and medical diagnostics

Subject:Guideline 1.4.1 - Safety: Medical App Accuracy Claims

Guideline 1.4.1 - Safety - Physical Harm Your app claims to provide health measurements that cannot be validated using the device's built-in sensors alone. Specifically, your app claims to [measure blood pressure / measure blood glucose / take X-rays / measure blood oxygen levels] using only the device sensors. Apps that claim to take x-rays, measure blood pressure, body temperature, blood glucose levels, or blood oxygen levels using only the sensors on the device are not permitted. Next Steps: Please revise your app to remove unvalidated health measurement claims, or submit documentation of regulatory clearance if applicable.

Consider Appealing

Only appeal if you have regulatory clearance (FDA 510(k), CE marking) or are using approved external hardware for measurements. Submit documentation with the appeal.

Generate Appeal

Before & After

Before — Rejected

App claims to 'Accurately measure your blood pressure using just your phone camera — no equipment needed!'

After — Approved

Blood pressure measurement feature removed. App now says 'Track your heart rate trends (estimated via camera). This is not a medical device — consult your doctor for accurate measurements.'

What changed: Blood pressure measurement via phone camera alone is explicitly prohibited. Heart rate estimation is acceptable with proper disclaimers.
