Apple has two separate App Store deadlines running on different clocks: existing regulated medical device apps in the European Economic Area, the United Kingdom and the United States must comply by early 2027, while new medical device apps face the rule immediately. Separately, and already behind it, Apple adjusted the China storefront of the App Store on iOS and iPadOS on March 15, 2026, three days after publishing the notice. Neither change is connected to the other; they simply both live on Apple’s developer news feed.
Both notices are the kind of dense, dated developer material that rarely gets covered outside Apple’s own pages, even though one of them carries a deadline still more than a year away and the other has already passed.
Key facts on both changes
| Item | Detail |
|---|---|
| Medical device notice | Update on regulated medical device apps in the EEA, UK and US |
| Published | March 26, 2026 |
| New apps | Immediately |
| Existing apps | By early 2027 |
| China storefront notice | Adjustments to the China storefront of the App Store on iOS and iPadOS |
| Published | March 12, 2026 |
| Deadline | March 15, 2026 |
New medical device apps face the rule now
Apple’s March 26, 2026 notice splits regulated medical device apps into two tracks. A new app submitted after that date is held to the requirement immediately, with no phase-in period. An app already live on the App Store before that date gets until early 2027 to reach the same standard. Apple’s notice names three regions bound by the rule, the European Economic Area, the United Kingdom and the United States, and does not name any other region.

Apple’s developer news item does not define what makes an app a “regulated medical device app” beyond the title of the notice itself, and it does not list the specific regulatory standard each region applies. The early 2027 date is also not narrowed to a specific day, week or month in the source Apple has published. The rule applies to the app, not to the phone or tablet it runs on, so the same requirement follows a qualifying app whether it is installed on iPhone 18 Pro, on iPhone Duo, or on an older device still receiving App Store updates.
China’s storefront adjustment, already in force
The China notice moved far faster. Apple published “Adjustments to the China storefront of the App Store on iOS and iPadOS” on March 12, 2026 and set the deadline three days later, March 15, 2026. That is one of the shortest publish-to-deadline windows anywhere in Apple’s 2026 developer news archive, shorter than the one-day and two-day turnarounds Apple has used for some of its age-rating notices this year.
Apple’s notice names the storefront and the two operating systems it covers, iOS and iPadOS, and gives no further detail on what specifically was adjusted. No later developer news item revisits or expands on the March 2026 China notice, and Apple’s recap of this month’s product announcements does not mention it either, since it was published six months earlier on the developer news feed rather than in a consumer release.
One deadline ahead, one already passed
| Medical device apps | China storefront | |
|---|---|---|
| Published | March 26, 2026 | March 12, 2026 |
| Deadline | Early 2027 (existing apps) | March 15, 2026 |
| Status as of September 12, 2026 | Still ahead | Already passed |
| Regions named | EEA, UK, US | China |
What Apple has not said
- Apple has not published a specific date within early 2027 for existing medical device apps to comply.
- Apple has not defined what qualifies an app as a regulated medical device app beyond the notice’s own title.
- Apple has not detailed what specifically changed in the China storefront on March 15, 2026.
- Apple has not said whether either notice will be revisited before iOS 27 ships Monday, September 14, 2026.
As of September 12, 2026, the China storefront adjustment has been in force for six months, while the medical device apps deadline for existing apps remains open, with early 2027 as the only date Apple has published for it.
