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 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
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
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.
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
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.
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
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.
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
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.
Checked against the vendor’s docs on : App Store Review Guidelines: 1.4.1; Apple: App Review (replying and appeals).
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 (US Eastern). The Diagnosis is back by . Pay for the Fix that day and it arrives as a pull request by , in time to build and resubmit before .
In past years Apple said reviews may take longer around the holidays: December 20 to 26 in 2024 (opens in a new tab), December 22 to 27 in 2023 (opens in a new tab), December 23 to 27 in 2022 (opens in a new tab). Apple hasn’t posted its 2026 dates yet (checked ). Approval stays Apple’s decision.
