Gap (pacer)
First page in the standard run carousel on watch: seconds ahead or behind target or ghost PR, with a large numeric cue and cyan header (first page in the run TabView).
Apple Watch experience
Built for runners, not shrunk from a phone app.
Runwiv on Apple Watch is a race-ready wrist HUD: live pace, heart rate, distance, and gap-to-target updates that stay readable mid-stride. When your crew sends Hype Bombs, you feel it instantly. The interactive preview below mirrors the same pages you swipe through on the watch (plus arcade and untethered modes).
Interactive watch preview
Tap a mode or let the tour cycle—pauses when you interact. Tilt moves the watch slightly (desktop).
Inside the bezel we use black backgrounds and system-style rounded type (like SF Pro Rounded on watchOS)—not the marketing Space Grotesk from the page header—so the mockup tracks the real HUD more closely.

Biometrics ring
Heart rate in a circular gauge with pace and distance tiles underneath—the second page in the run carousel.
Scan to join
When the phone has pushed a lobby session, the watch shows a QR your crew can scan—the third page in the carousel.
Main HUD
Primary pace-first page: HR · distance · elapsed, then zone dots and optional LIVE badge. It is the fourth swipe on the watch; we keep it selected by default here so the first thing you see is the hero HUD most runners use most.
Effort & watts
Running power, grade-adjusted vs GPS pace, effort target bar, cadence and left/right balance—fifth in the carousel.
Race & splits
Predicted finish, average vs last-km pace, glycogen cue, pace gap vs target and km to go—sixth in the carousel.
Recovery
HRV, readiness, VO₂ max, training load, sleep and recovery hours—seventh in the carousel.
More (legacy scroll)
Extra metrics in a scrollable page—the eighth and last page of the standard run carousel.
Hype flash
On the watch this is a full-screen cyan sheet with a bold bolt icon—matching the system symbol—so the preview reflects what you see and feel as haptics, not a decorative emoji.
Arcade modes
When the host picks Turf War, Alleycat, or Infection, the watch swaps to mode-specific pages (sample: Turf War timer and territory bar).
Untethered solo
If the phone is unreachable, the watch offers a local HealthKit solo run with START SOLO / STOP—then syncs when you reconnect.
Squad start
Representative countdown for synchronised starts driven from the phone session; exact copy may vary by build.
Why this feels different on race day
Readable in motion
Hierarchy is tuned for running cadence: pace first, then effort and context, with low-friction color cues.
Phone + watch continuity
Host from phone, run from wrist. Sessions, routes, and squad context stay aligned across surfaces.
Live social energy
Watch haptics, spectator map reactions, and squad starts make solo effort feel communal without visual clutter.
How runners use it
1. Set session — choose route, mode, and target pace in app.
2. Start synced — watch shows countdown and transitions to HUD.
3. Adjust in real time — read gap and HR without breaking rhythm.
4. Feel the hype — spectator and squad support arrives as haptic cues.
