# RelevanceKit Provide on-device contextual clues that increase a widget's visibility in the Smart Stack on Apple Watch. RelevanceKit tells the system *when* a widget is relevant -- by time, location, fitness state, sleep schedule, or connected hardware -- so the Smart Stack can surface the right widget at the right moment. Targets Swift 6.3 / watchOS 26+. > **Beta-sensitive.** RelevanceKit shipped with watchOS 26. Re-check Apple > documentation before making strong claims about API availability or behavior. See [references/relevancekit-patterns.md](references/relevancekit-patterns.md) for complete code patterns including relevant widgets, timeline provider integration, grouping, previews, and permission handling. ## Contents - [Overview](#overview) - [Setup](#setup) - [Relevance Providers](#relevance-providers) - [Time-Based Relevance](#time-based-relevance) - [Location-Based Relevance](#location-based-relevance) - [Fitness and Sleep Relevance](#fitness-and-sleep-relevance) - [Hardware Relevance](#hardware-relevance) - [Combining Signals](#combining-signals) - [Widget Integration](#widget-integration) - [Common Mistakes](#common-mistakes) - [Review Checklist](#review-checklist) - [References](#references) ## Overview watchOS uses two mechanisms to determine widget relevance in the Smart Stack: 1. **Timeline provider relevance** -- implement `relevance()` on an existing `AppIntentTimelineProvider` to attach `RelevantContext` clues to timeline entries.
