Rally Clock: Stage Timing

Rally Clock is a timing and log app for rally control workers: a clock you can trust, one big button to capture cars, and a log that gets to scoring without anyone retyping a paper sheet at midnight. It captures data. It doesn't score. Every row is saved on the device the moment it's written, so a flat battery loses nothing already logged. TIMING A CONTROL • Pick what your control is: Start Control, Flying Finish, Stop Control, ATC, the In and Out controls at MTC, Regroup and Service, and the rest. The screen changes to suit it. • CAPTURE is pressed on finger-down, with a lockout so one car doesn't register twice. • Car numbers on a big keypad, with letters a tap away. Capture first if you missed the number, and add it afterwards. • Start control: each car gets the next free start time as it's logged, with the gap between cars you choose, and a countdown to the second. A warning shows when the next start is only seconds away. • Hold to stop a start from the countdown, and the car goes back in the box. A crew late to the line gets a new start time, and the one they missed is kept for scoring. • Out controls send cars one per minute: a second car in the same minute is given the next free one, and the log says whose minute it was. • Stop control: type in finish times relayed from the flying finish. A car that leaves without one is logged as "No time yet", and linked to its time when it comes in. • Notes for a car or for the control: a hold, a red flag, a crew on foot. • Void, never delete: a crossed-out row keeps its place, which is what scoring needs. A CLOCK YOU CAN TRUST • Set it from an internet time server, copy another device at the stage, or set it by hand at the top of a minute. • The phone's own clock is never changed. If it jumps, Rally Clock holds steady and says so. • Every clock correction is written into the log, so scoring can allow for it. • Accuracy is shown, not assumed: a copy says how closely it matched, such as ±5 ms. GETTING THE LOGS BACK • Hand over to a sweep car or HQ over a Wi-Fi network or phone hotspot. No internet or phone signal needed. • Handing over copies the log: the control keeps everything. Hand over as often as you like; only new or changed rows are added. • Collecting devices pass on everything they hold, so a sweep car can hand its whole collection to HQ. • Review shows which controls are short, and by which cars. • Export as a spreadsheet (CSV) or data file (JSONL) through the share sheet. EVENT SETUP • An organizer fills in the event once. A course car hands it out, and each volunteer picks their control from a list. TRIP METERS • Several trip meters, from GPS speed, in miles or kilometers. • They keep counting with the screen locked in its mount and while you use other apps. • Calibrate against an event's official odometer check. • Reset takes a long press, and offers Undo. LAP TIMER • For a test day: START as the car first crosses the line, CAPTURE every lap, STOP on the cool-down. Each lap shows its gap to the best. ALSO • Controls on the left for a left thumb. • A tablet with a keyboard: type the car number, and Enter presses the big button. • Light and dark themes. PRIVACY No accounts, no ads, no analytics. Your data stays on your device unless you hand it over or share it. Your position is never stored or sent.
