Supported ways to intervene on app-open and on a schedule (non-blocking) — Screen Time / Shortcuts

I'm building a consumer iOS app that helps users be more intentional about opening distracting apps. It never hard-blocks; it only nudges. I have Family Controls (Distribution) approved and a working TestFlight build using FamilyControls / DeviceActivity / ManagedSettings. I've confirmed from testing and the forums that:

ShieldActionResponse is only .none / .defer / .close (no supported way to open my main app from the shield extension — threads 719905, 793060).
ShieldConfiguration is a static snapshot (no countdown/animation; FB14237883).
DeviceActivityMonitor events are threshold/schedule based and cannot hook "the app was just opened," and on iOS 26 eventDidReachThreshold fires immediately/incorrectly (thread 808470).

I'd like to confirm the supported approaches for these UX patterns (each = every-app-open vs on-a-schedule):

On app open, present my own full-screen UI (a brief non-blocking "pause") without requiring the user to manually create a Shortcuts personal automation. Is there any supported API for this, or is a user-created Shortcuts automation the officially recommended path?
On app open, deliver a local notification (rather than UI) — supported only via a user-created Shortcuts automation, or is there another way?
On a schedule / at fixed intervals, automatically bring my app's UI to the foreground (e.g., re-show a screen every N minutes) — I believe this is not allowed (apps can't self-foreground); can you confirm, and is a user-tapped notification the only path?
On a schedule / at fixed intervals, send repeating local notifications while a usage limit is exceeded — given the iOS 26 eventDidReachThreshold regression, what's the recommended way to reliably detect "over limit" and drive repeating reminders?
Some third-party apps appear to open their main app from a shield/monitor context. Is there any supported mechanism enabling that which I may have missed?

I'd rather build on a supported path than risk anything review-sensitive. Guidance (or where to file an enhancement request) is appreciated. Thank you.

Thanks for the post. Its interesting.

It is crucial to emphasize that launching an application without user interaction will be in violation of all user policies.

There is no callback mechanism that triggers when an application is opened, allowing you to connect to your own user interface. Additionally, there are no NSUserActivity, Shortcuts-provided intent, URL scheme, App Intent, or Live Activity hooks that the system automatically triggers for you when another application is launched. While users can create Shortcuts automation, this functionality is solely for the user’s use. iOS does not provide a supported API for an application to programmatically bring itself to the foreground, and Family Controls does not grant any exceptions for this purpose.

I would recommend a APN push notification as reminders, however that still cannot bring your app to the foreground or force open your UI. But you can wake up the app briefly in the background only. Cannot preset UI and cannot foreground the app.

Hope this is helpful to you, looking for ideas from other developers.
