Guideline 2.5.19 · 2.3.1(a) · Notes for Review
Describe your feature flags with specificity.
Paste your Remote Config or LaunchDarkly flags. ReviewNotes sorts your paywall tests, kill switches, staged rollouts, region gates, dormant features and debug menus, catches leftovers that look like hidden features, and writes App Review notes you can paste straight in.

- 4000-byte counter
How it works
From a flag dump to notes a reviewer can follow.
01 Paste your flags
Drop in a Firebase Remote Config template, a LaunchDarkly export, a .env file or just a list of names.
02 We sort them
Each flag gets a category from its name, value and targeting rules: paywall test, kill switch, rollout, region gate, dormant or debug. Override anything.
03 Leftovers get caught
Names with debug, test, staging, internal or bypass in them are the classic “hidden feature” rejection. The checklist fails if one is on.
04 A note Apple can follow
Every remote feature with what it does, its state during review and how to reach it. Counted against the 4000-byte limit, ready to paste.

What you get
Everything a reviewer needs, nothing they can trip on.
Specific, not generic
Apple rejects generic descriptions. Each flag gets a name, what it does, its state during review and the exact tap path.
Reads your real exports
Firebase Remote Config, LaunchDarkly, plain JSON, .env or a list.
Paywalls, rollouts, regions
A/B tests, percentage rollouts and EU-only screens get their own section, so the reviewer knows why their screen may differ.
Catches debug leftovers
debug, test, QA, staging, internal, bypass, cheat: if a reviewer can reach it, it reads as hidden. The checklist fails until it's off.
4000-byte counter
Apple limits the Notes field to 4000 bytes, not characters. We count both and offer a compact layout.
Private by design
Nothing is uploaded. Drafts autosave in your browser.
Guide · App Store guideline 2.5.19
What Apple actually says about hidden features
Quoted from the App Review Guidelines, last updated 16 October 2026. Checked on 23 October 2026.
“Don’t include any hidden, dormant, or undocumented features in your app; your app’s functionality should be clear to end users and App Review.”
“All new features, functionality, and product changes must be described with specificity in the Notes for Review section of App Store Connect (generic descriptions will be rejected) and accessible for review.”
So are feature flags allowed?
Yes. Remote config, A/B tests and staged rollouts are everywhere on the App Store. The problem is undisclosed behaviour: a reviewer sees one app, and a flag flip later turns it into another. That's what 2.5.19 calls hidden or dormant features.
The fix is disclosure. Apple's own submission checklist asks you to “Include detailed explanations of non-obvious features and in-app purchases in the App Review notes, including supporting documentation where appropriate.” Your Notes for Review should say which features are remotely controlled, what state they're in during review and how to reach them, and confirm that developer switches are off.
Keep it under the limit: “The Notes field can contain up to 4000 bytes.”
