Lykta: Agent Live Activities

Lykta lets your AI agents show their work on your iPhone: a Live Activity on the Lock Screen and in the Dynamic Island while a job runs, and a notification that arrives like a message from a person when it's done. Your agent designs each activity for its subject: a progress ring for a build, the steps of a deploy, a drawing of the printer for a 3D print, a CPU chart for a server. Lykta draws it with native SwiftUI and keeps it current as the agent sends changes. Timers and progress bars run on the phone, so the agent only sends what changed, and a new layout needs no app update. GETTING STARTED 1. Open Lykta, tap Examples and send any example to your phone to see it live. 2. Tap Copy Agent Setup and paste it into Claude Code, Codex or any other agent that can run shell commands. 3. The agent runs one command. It installs lykta, a small command for sh or PowerShell, saves your gateway address and token, and reads instructions written for agents. From then on it starts, updates and ends activities and sends notifications as it works. LIVE ACTIVITIES • Layouts are built from stacks, text, SF Symbols, timers, progress bars, gauges, charts and SVG drawings, with fonts, colors and padding. • Each activity has its own Lock Screen view and Dynamic Island presentations, and appears in StandBy and in the Apple Watch Smart Stack. • Buttons, toggles and links. A toggle or button can change the activity's data on its own, so a checklist or a pause button works while no agent is running. • Agents read every press, so you can answer an agent's question with a tap. • An alert lights up the screen for the moment that needs you, such as a failed step. NOTIFICATIONS • The sender's name and picture, like a message from a person, with one thread per sender. • A sound of the agent's choosing and an image, such as a photo of the finished print. It works for anything an agent can follow: a build, a test run, an App Review, a 3D print, a recipe or a shopping list. SELF-HOSTING The source is on GitHub. You can run your own gateway with Docker and your own Apple Developer account and build the app against it; the repository includes a setup guide. PRIVACY Lykta has no accounts, analytics, advertising or tracking. The App Store app connects only to a gateway run by its developer. The gateway keeps your phone's push tokens, what your agents send, and a diagnostic log that holds no activity or notification text. It deletes ended activities after about a week, notifications after a day and diagnostics after 14 days. Reset in the app deletes your phone's data from the gateway, and its backup copies expire within 14 days. Dynamic Island presentations need an iPhone with the Dynamic Island; on other iPhones, activities appear on the Lock Screen. Lykta is an independent app, not affiliated with Anthropic or OpenAI.
