About RC Sentinel

Rally Comp Sentinel is a dedicated backup GPS logger for offroad rally racers. Your race computer does the navigating—RC Sentinel quietly runs alongside it, recording a complete, independent track of your stage. If your primary device fails, freezes, or loses power mid-stage, your ride isn't lost: it's safe on your phone.
Built for the realities of desert and offroad rally, every GPS coordinate is written and flushed to storage the moment it's captured. No buffering, no "save on stop," no single point of failure. Start it, pocket your phone, and ride.
Review any session and share it as CSV or GPX, or send it straight to RallyComp. Keep the rulebook, schedule, service routes, emergency contacts, and tech checklist on your phone—available even with no signal.

Key Features
- Protect Your GPS Track — Each fix is flushed to disk immediately, so a crash or dead battery can't take your data with it.
- Record a Backup Track — Runs in the background capturing speed, heading, elevation, distance, and time, with a continuously growing point count.
- Export Your Race Tracks — Review any session and share it as CSV or GPX, or send it straight to RallyComp.
- Coordinate Tech & Bivouac — Lightweight event messaging for tech inspection and bivouac logistics. (Not for race communication—always use your RallyComp device for that.)
- Access Race Docs Offline — Keep the rulebook, schedule, service routes, emergency contacts, and tech checklist on your phone, available even with no signal.
- Background Operation — Keeps logging while your screen is off, with a clean, glanceable live readout showing both local and UTC time.
- Log From Your Apple Watch — Start, monitor, and record your GPS track straight from your wrist, so you can keep logging even without reaching for your phone.
- Built for Officials & Backends — Standard CSV and GPX output, metric units, and UTC timestamps—works with the tools you already use.
