Appinspo is a curated inspiration site for app interfaces, organized by device — mobile, desktop, smartwatch, Vision Pro — plus dedicated sections for icons and illustration.
The device-based split is the useful part — it saves you from wading through phone screenshots when what you actually need is watch-face or spatial-interface reference.
Good for UI designers who want current visual trends across multiple device categories in one place, especially newer surfaces like Vision Pro where dedicated galleries are still rare.
It's a newer entrant in a crowded field of app-inspiration sites, and it isn't clear from the site how large the underlying library actually is compared to more established names like Mobbin.
