Tactical Sport Companion
Every run you finish becomes a ghost. Pick one, and race it - your pace against your own, live, on a shared track. No feeds. No leaderboards. Just ahead or behind.
iPhone required · Apple Watch companion coming soon
The whole idea
Start a run and RunChasr calls up a ghost - one of your own past runs, replayed at the exact pace it happened - and races it against you in real time. Pull ahead and it falls behind. Fade and it catches up.
Two dot-matrix silhouettes, one shared track, always live. No glance required to know direction - only to know by how much.
Close the loop
Beat your ghost or lose to it - either way you get a full tactical report: time, distance, and pace side by side with what your ghost did at the same point. Tag the effort, log a note, share the result.
And the run you just finished automatically becomes tomorrow's ghost - the loop never needs manual setup.
System Protocol
Your last run by default, or a computed suggestion - Personal Best, Longest Distance, Recovery Standard.
Start your stride. RunChasr relays performance gaps relative to target location in absolute real-time.
Save your workout metrics. The effort concludes with a conclusive verdict and automatically queues as your next ghost target.
Engineering Details
A callout when you take the lead or lose it - never a generic timer nagging you mid-run. An opt-in spoken summary every 5 or 10 minutes for hands-off updates.
The race, live on your wrist - a compact version of the same silhouette track, with its own takeover flash and haptic.
Sync route paths, distance, duration, and calories automatically with your existing iOS Health records.
