FEATURES

Built for the field

Resilient to interruptions, quick to operate even with gloves on, and designed so a single person can run the finish line without missing a read.

01

Professional UHF reading

Direct integration with the Impinj UHF6 reader: continuous reading, up to 6 EPC prefix filters and power from 5 to 33 dBm.

02

Millisecond precision

Every read is recorded as HH:mm:ss.SSS, in real time of day or in race time depending on the mode.

03

Anti-closing protection

Foreground service with a persistent notification, screen always on and double confirmation to exit during a race.

04

Beep and vibration alerts

Configurable beep and optional vibration on every read. Volume is controlled with the device’s own keys.

05

Real-time FTP

Automatic upload of the TXT every 30 seconds, without overwriting old files and with staggered alerts if the network fails.

06

Backup to OneDrive or Drive

Periodic copy to a folder that the cloud apps sync on their own. One more backup, with no infrastructure cost.

THE SCREENS

Two views for every situation

A full view for the finish operator, with fine control, and a minimal view for seeing bibs from a distance.

01 · MAIN SCREEN

The timing view

Large clock at the top, status bar with the mode and filters, control buttons and a real-time list of reads.

  • HH:mm:ss clock: green when running, red when stopped
  • RFID indicator: ○ stopped, ◐ open, ● reading
  • Bright green background while reading
  • One-tap manual bib entry
  • Edit a record by tapping its row

TIMING MODES

Three modes, each event with its own

Chosen in the settings, they adapt the behaviour of the reader and the record list.

01

Single pass

The classic approach: each chip is accepted only once and later reads are ignored. Ideal for popular race finishes, triathlons and walks.

02

Laps

Each chip can pass several times, with a configurable minimum time between reads. The header shows the highest lap. Perfect for circuits and cycling.

03

Time-trial start

The reader reads continuously and each chip stays pending until you press ACCEPT: the time is taken at the exact moment of the tap. Ideal for time trials.

SETUP

Complete yet clear

All settings are organised into cards by area. Critical fields, such as the file name and start time, are highlighted to prevent mistakes. From any section you can return to the timer with a single tap.

CHIP READING

Two chip formats

The two most common EPC formats in professional timing, selectable under Settings → Reading.

01

Cronomach mode

The bib is written in decimal in the last characters of the EPC and is taken as is, with no conversion. Compatible with the chips commonly used at popular races.

02

TS mode

The EPC is read as 4 hexadecimal filter characters plus 4 bib characters, which are converted to decimal automatically. The typical format of Time Source and professional sports chips.

BACKUP

Triple backup of the times

Losing the times is a timer’s worst nightmare. That’s why the app writes to three destinations at once: a failure in one never puts the data at risk.

1

On the device itself

A TXT file in internal storage or in the folder of your choice, written after every read. It is the reference copy and is never lost.

2

Real-time FTP

Automatic upload to the FTP server every 30 seconds so the organisers can see the times live. If a file already exists on the server, it is renamed.

3

OneDrive or Drive

Periodic copy to a folder that the official cloud apps sync on their own. A standalone backup with no dependencies.
