How to Customize the iPhone Action Button (15 Pro and 16+)

Action Button for Knowledge Work

iPhone 15 Pro and iPhone 16 Action Button has eight built-in options, plus "Shortcut" which unlocks any automation.

For knowledge workers: configure Action Button → Shortcut → a Shortcut that opens Nemos in voice capture mode. Single button press from any state → immediate voice capture. This is faster than any software-based shortcut because it works from lock screen and doesn't require facial recognition first.

Secondary use cases: configure as a Shazam trigger for music identification (captures to Shazam's history, not searchable — share result to Nemos afterward), or as a language translation trigger for travel.

The right configuration depends on your primary capture bottleneck. For knowledge workers who capture ideas via voice throughout the day: Nemos voice capture is the clear winner for Action Button.

Where Nemos fits

Nemos is a private second brain for iPhone that solves the "I saved it somewhere" problem. Every screenshot, voice memo, PDF, and link you save gets OCR'd, transcribed, and indexed on-device using Apple Foundation Models. Find anything by typing one word. Free. Apple-only. Free on the App Store.
