UltraLog

UltraLog is a real-time, offline-first tracker for endurance and ultra training sessions.

Follow an athlete live - elapsed time, distance, pace, speed and breaks - straight from your iPhone. Built for coaches, crew and observers who need reliable numbers in places without signal.

• Live session tracking: start, pause, resume and finish, with stats derived on the fly • Works offline: peer-to-peer sync over Bluetooth and local network - no internet required • Join a shared session in seconds via QR code or session ID • Route preview on the map and a clean session summary • Privacy-first: no account, no ads, no tracking

UltraLog records location only to geotag your session events and compute your stats.
