Just learned from @atpfm that the Apple Feedback app is built into iOS. To open it you must navigate to applefeedback:// in Safari. 🧐

The app is:

• Not on home screen
• Not in App Library
• Can’t find with Spotlight
• Not on App Store
• Disappears from the app switcher when you switch away, even if paired with another app in Split View
• Disappears from Slide Over when swiped away

From which it seems:

• Apple loves receiving our feedback.
• Secret URLs are cool, I guess.
