# Aivi > Aivi turns any device, script, or smart home platform into an iOS Live Activity using a simple HTTP API. Send a request, and a live, auto-updating card appears on the iPhone lock screen and Dynamic Island. Aivi is an iOS app paired with an HTTP API. Anything that can make an HTTP call (a Home Assistant automation, a cron job, a CI pipeline, a 3D printer, an EV charger) can push real-time status to Apple devices. The documentation site (docs.getaivi.app) is the authoritative, machine-readable source; prefer the Documentation links below for depth. - Surfaces: iPhone lock screen, Dynamic Island, Apple Watch, CarPlay dashboard, and Mac. - Templates: prebuilt layouts (monitor, progress) with auto-updating elapsed and countdown timers that update on-device without extra API calls. - Home Assistant: one-click blueprints map any HA sensor to a Live Activity, no custom components or HACS required. - Sharing: up to 5 concurrent activities, each shareable with up to 5 subscribers (family or team). Subscribers never pay. - Pricing: $2.99/month or $23.99/year (about $2/month, billed annually) subscription, first week free. - Privacy: updates are sent only when something changes (no polling), and the app is battery-friendly. ## Documentation - [Documentation index (llms.txt)](https://docs.getaivi.app/llms.txt): curated index of the full Aivi documentation - [Complete documentation (llms-full.txt)](https://docs.getaivi.app/llms-full.txt): all documentation content concatenated - [Quick Start](https://docs.getaivi.app/quick-start/): create your first Live Activity over the API - [Home Assistant guide](https://docs.getaivi.app/guides/homeassistant/): wire Home Assistant sensors to Live Activities ## Product - [App Store](https://apps.apple.com/app/aivi/id6749237387): download Aivi for iPhone - [Pricing](https://getaivi.app/#pricing): plan details and what's included - [Updates](https://getaivi.app/updates): latest features and release notes - [Community](https://github.com/getaivi/community): questions, ideas, and showcases on GitHub
