What it is

Mockup categories include iPhone, Android, iPad, Mac, desktop, Apple Watch, Apple TV, TV, and browser. Layout templates include Single Center, Side by Side, Grid 2x2, Isometric, and Phone + Tablet. Scene presets include Cosmic Hero, Abstract Center, Holo Laptop, and Full Responsive. Device choices include iPhone models, Pixel 7 Pro, and Nothing Phone. Canvas modes cover General, Social, App Store, and Play Store, with landscape 16:9, portrait 9:16, square 1:1, ultrawide, and Studio Display formats.
