Guideline 1.4.1 is the App Store safety rule for medical apps that could give wrong health data or be used to diagnose or treat patients. Apple asks for proof behind every health measurement and rejects readings it can’t validate.
**Short answer**
List every health number the app shows and how it is measured. Remove any reading taken from the phone’s own sensors that Apple names, such as blood pressure or blood oxygen, unless it comes from a connected, validated device. Publish the data and method behind each accuracy claim, add a reminder to check with a doctor, and attach any regulatory clearance in App Review notes.
Rather not fix it yourself? [**App Fix Ticket**](https://app369.com/fixed-price/flutter-firebase-bug-fix/) starts with a fixed-price diagnosis, then a fixed price for the fix before any fix work.
## **What triggers 1.4.1, and the fix**
1. 01 ### **The app measures vitals with phone sensors only**
> “For example, 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.” [**Apple, Guideline 1.4.1**](https://developer.apple.com/app-store/review/guidelines/#1.4.1) Readings of x-rays, blood pressure, body temperature, blood glucose or blood oxygen taken using only the phone’s own sensors are named as not permitted. Read the value from a connected medical device, or remove the feature.
2. 02 ### **Accuracy claims have no data behind them**
> “Apps must clearly disclose data and methodology to support accuracy claims relating to health measurements” [**Apple, Guideline 1.4.1**](https://developer.apple.com/app-store/review/guidelines/#1.4.1) Words like “clinically accurate” or a stated error margin need a published method and results. Link the study or validation report in the app and in App Review notes, or remove the claim.
3. 03 ### **No reminder to see a doctor**
> “Apps should remind users to check with a doctor in addition to using the app and before making medical decisions.” [**Apple, Guideline 1.4.1**](https://developer.apple.com/app-store/review/guidelines/#1.4.1) Apple asks medical apps to remind users to check with a doctor. Put a clear reminder where the app shows results or advice, not only in the terms.
4. 04 ### **Regulatory clearance was not shown**
> “If your medical app has received regulatory clearance, please submit a link to that documentation with your app.” [**Apple, Guideline 1.4.1**](https://developer.apple.com/app-store/review/guidelines/#1.4.1) Also check: if the app or device has FDA or other regulatory clearance, App Review can’t see it unless the submission links to it. Add the link in App Review notes.

## **Rather hand it over?**
Fixed scope, fixed price, paid upfront. The work happens in writing; no call needed.
**Resubmit before Apple’s holiday slowdown**
Pay for the Diagnosis and send the rejection and access to the app by Monday, December 7 (US Eastern). The Diagnosis is back by Thursday, December 10. Pay for the Fix that day and it arrives as a pull request by Thursday, December 17, in time to build and resubmit before December 20.
In past years Apple said reviews may take longer around the holidays: [December 20 to 26 in 2024 (opens in a new tab)](https://developer.apple.com/news/?id=iwvebnw2), [December 22 to 27 in 2023 (opens in a new tab)](https://developer.apple.com/news/?id=uijoypq9), [December 23 to 27 in 2022 (opens in a new tab)](https://developer.apple.com/news/?id=xpkhwg3l). Apple hasn’t posted its 2026 dates yet (checked October 30). Approval stays Apple’s decision.

Questions
## **More on this rejection**
**Should I reply to App Review or appeal? **+
Reply first. Apple says you can correspond with App Review in App Store Connect to resolve the issues before resubmitting, which is the place for a demo account, a screen recording or an explanation. Appeal to the App Review Board only if you believe App Review misunderstood the app or treated you unfairly. Apple allows one appeal per rejected submission and asks for specific reasons the app complies.
**Does a wellness app fall under 1.4.1? **+
It can. Apple applies more scrutiny to apps that could give inaccurate health data or be used to diagnose or treat patients, so any health reading needs data behind it.
**Can you fix it for me? **+
Yes, through the App Fix Ticket: you send the rejection message and access to the app, Simon writes a diagnosis of what App Review hit and how to fix it, then fixes the code so you can resubmit. Each step has a fixed price, paid upfront. Approval stays Apple’s decision; the ticket covers the fix.
