Quick answer: A guitar interface lets you plug straight into your iPhone for amp-sim apps and recording — practice with headphones or lay down tracks anywhere. Get a simple plug-in interface for practice, a USB-C audio interface for recording quality, or a modeling interface with built-in tones. Low latency and clean input are what matter most.

Pro tip — for iPhone 15 and newer, get a USB-C interface (not Lightning). Newer iPhones use USB-C, so a USB-C interface plugs in directly; older Lightning iPhones need a Lightning interface or adapter. Also use wired headphones for monitoring — Bluetooth adds latency that makes playing in time impossible. Wired in, wired out, for tight timing.
