Runtime - Offline Music

Music you own, on your watch, offline.

Your music. On your wrist. Completely offline. Runtime is the simplest way to play your own music on your Apple Watch — no account to create, no subscription to pay, and nothing that ever touches the internet. Load the songs you already own, create playlists for your runs, send them to your watch, and head out with nothing but your wrist. Built for runners, walkers, and anyone who'd rather leave the phone at home.

WHY RUNTIME No account — never sign up, log in, or hand over an email. No subscription — no monthly fee, no premium wall, no upsells. Fully offline — no servers; no Wi-Fi or cellular needed to sync or play. Nothing leaves your device — no tracking, no ads, no analytics. Zero bytes collected.

MADE FOR THE RUN Take only your Apple Watch — your phone can stay home. Big, glanceable controls: play, pause, skip, back. A clean, distraction-free terminal-style interface that's easy to read mid-stride.

GOOD TO KNOW Runtime plays music you already own. It's a player, not a streaming service, and doesn't include a catalog of songs. Audio plays to your Bluetooth headphones through your Apple Watch.

No noise. No tracking. No subscription. Just your music, fully offline.
