Watch live work unfold on your Lock Screen
Live Activities stay on your Lock Screen while something is still running. Follow an agent working through a task, a script working through a backlog, a deploy moving through steps, or a number that keeps changing.
await activitysmith.liveActivities.stream("sales-hourly", { content_state: { title: "Sales", subtitle: "last hour", type: "stats", metrics: [ { label: "Revenue", value: "$2430", color: "blue" }, { label: "Orders", value: "37", color: "green" }, // ... ], },});The metric you keep refreshing, right on your Lock Screen
ActivitySmith lets you display any value on your Lock Screen with widgets - SaaS metrics, revenue, number of users, uptime, or anything else you want to track.
await activitysmith.metrics.update("deploy.success_rate", 99.9);
Let your AI agent report back to your iPhone
Connect the official ActivitySmith MCP server to your coding agent so that it can notify you when work is done, blocked, or ready for review, and keep longer tasks visible with a Live Activity on your Lock Screen.

FAQ
Do I need to build my own mobile app to receive these alerts?
No, that's the best part. ActivitySmith provides a dedicated, ready-to-use iOS app. You don't have to write a single line of Swift or manage App Store submissions. Just download our app, pair your device, and start pushing alerts from your backend in minutes.
Do I need an Apple Developer account or push certificates?
No. Because you are sending alerts to the ActivitySmith app rather than your own custom app, we handle all the APNs (Apple Push Notification service) handshake. You don't need to manage certificates, identifiers, or provisioning profiles.
Can I use ActivitySmith to send notifications to my own app's users?
No. ActivitySmith is not an SDK for your own mobile apps. It's a service that lets you send notifications from any backend to the ActivitySmith iOS app.
Can I use ActivitySmith without an AI agent?
Yes. AI agents are optional. You can send Push Notifications and start or update Live Activities from any backend through the REST API or official SDKs. Webhook integrations, n8n workflows, and Zapier Zaps can also send deployment updates, automation results, business metrics, and other events to your iPhone or iPad.
Browse integrationsWhat is the benefit of using the ActivitySmith app instead of Slack/Discord?
Standard chat apps don't support iOS Live Activities or rich Push Notifications. ActivitySmith gives you a persistent Live Activity on your Lock Screen or Dynamic Island for things like 'Deploy Progress' or 'Server Migration Progress' that you simply can't do with a standard push notification.
