What matters, right on your Lock Screen and Dynamic Island. Island Pulse gives you an API endpoint and a secret Bearer token. Your automations send HTTPS POSTs with JSON; your iPhone turns those updates into Live Activities on the Lock Screen and Dynamic Island. Use it for deploys, sales pings, home automations, or anything you can trigger over HTTPS. HOW IT WORKS • Copy your endpoint and Bearer token from the app and use them in Shortcuts, GitHub Actions, cron, Zapier, or your own code. • Every request must include a job_id so updates route to the right Live Activity stream. • Use title for what people see as the activity title. Use message for the main text. • History stays on this device so you can see what arrived recently. FREE • One active job at a time (one concurrent Live Activity stream for your account) • Title and message on the Lock Screen; you define what they mean • Default layout only • Live Activity plus the last 10 completed runs in your in app log PRO • Multiple concurrent jobs within iOS limits* • Last 30 days of run history • Custom job names and icons • Longer runs with automatic renewal when you need an activity to stay visible • Premium themes and layout options *Subject to iOS system limits (for example, up to five concurrent Live Activities per app) and device capabilities. Subscriptions are billed through your Apple ID. Pricing and renewal terms are shown in the app before purchase.

Read full description

Pi Relay is a companion iPhone app for the Pi coding agent. It lets you connect securely to your own Pi remote-control server, browse active projects and sessions, and continue conversations from your phone. Pairing is simple: install the Pi remote-control extension on the machine running Pi, open the pairing QR code, and scan it with Pi Relay. Once paired, you can switch between remotes, view project sessions, read conversation history, send new prompts, abort running work, and request context compaction with /compact. Pi Relay is designed for users who already run Pi on their own computer or development environment and want a lightweight mobile companion for monitoring and continuing work away from the desktop. Key features: - QR-code pairing with your Pi remote-control server - Remote list with quick switching and unpairing - Project and session browsing - Conversation view with selectable and copyable messages - Runtime status and context usage display - Prompt sending, abort support, and /compact support - Live session updates while the app is active Pi Relay requires a running Pi remote-control extension/server. The extension is available at: https://github.com/zerray/pi-remote-control
