About this app

Battle Ground Race Timing records every lap of a trail or loop race by tapping runners' NFC wristbands with a phone. It is built for race days with no internet: the timing runs entirely on phones at the venue, and results go online when a connection is available.

FOR VOLUNTEERS
• Sign in once and the phone stays ready for the whole event, even offline.
• Tap a runner's wristband: the phone confirms instantly what was counted, e.g. "Lap 3 of 5 · 15 of 25 km" or "FINISHED".
• Double taps, early taps and taps after the cutoff are caught automatically.
• Assign wristbands to bib numbers and check any band in seconds.
• Works with the phone's own NFC or a USB-C NFC reader.

FOR RACE DIRECTORS
• One phone becomes the race hub: it collects taps from every timing phone over its Wi-Fi hotspot.
• Set up distances (e.g. 50K, 25K, 10K), loop length, start times and cutoffs.
• Optional start taps: a late starter's time runs from their own start.
• Live race view: who is running, overdue, finished, DNF or DNS.
• Leaderboards and results per distance, with CSV export.
• Review screen for unknown wristbands and questionable taps; add missed laps, mark DNF / DQ / DNS, or remove a runner.
• Manage volunteer accounts and revoke a lost phone.

BUILT FOR THE COURSE
• No internet needed at the venue; every tap is saved on the phone first.
• If the hub is out of range, phones keep recording and send everything when it is back.
• Results also sync to the online leaderboard for families and crews.

Made for Battle Ground India events. Accounts are created by the race organiser.
