Apple debuts ARKit 4 with new depth capabilities and Location Anchors to place AR experiences throughout cities, and expands face tracking to more devices

Context & Ripple Effects
ARKit has shipped on a yearly cadence since its 2017 debut, and each version has widened what developers can anchor virtual objects to: correctly-sized objects on a table first, then shared sessions across four iOS devices, then real-time occlusion of people alongside RealityKit tooling.
ARKit 4 continues that arc along two axes at once — scale and reach. Location Anchors move anchoring from a room to whole cities, while expanded face tracking loosens what had been a hardware constraint since face tracking arrived exclusively on iPhone X. Depth capabilities push fidelity further on supported devices.
First-order effects
- Developers can now build AR experiences pinned to specific places throughout a city rather than re-anchored per session, making location-based AR apps practical instead of demo-grade.
- Face-tracking apps gain a much larger addressable install base as the feature leaves its iPhone X-era hardware exclusivity behind.
Second-order effects
- Location Anchors make physical venues — stores, landmarks, transit points — into programmable surfaces, giving local businesses a reason to commission AR content the way they once commissioned web pages.
- Google's rival AR stack, which Super Ventures' coverage framed as ARKit's key technical contrast back in 2017, faces pressure to match city-scale persistence or cede the developer mindshare Apple has cultivated through successive ARKit releases.
Third-order effects
- If the pattern holds, AR shifts from per-device novelty to a persistent, location-indexed layer over cities — and whoever controls the anchoring infrastructure controls discoverability within it, an App Store-style gatekeeping role extended to physical space.
The trend: Apple is scaling AR from tabletop demos to persistent, city-wide layers through its annual ARKit cadence, widening hardware support as it goes.
