JCLOCK
The most advanced digital race clock, controlled from anywhere. Bluetooth, Wi-Fi, browser, API — every control method built in.
Built for professional race timers and event directors who need reliable, flexible clock control without compromise.
Three Simultaneous Connections
Up to three operators can control the same clock at the same time via Bluetooth. Assign roles, split responsibilities, or give your team independent access — no conflicts, no waiting.
Time Controls
Count up, count down, time of day — with configurable ceilings, custom start points, and live pause/resume. Every timing scenario covered.
Brightness Controls
Manual brightness slider with auto-brightness to adapt to changing conditions — from gym lighting to direct sunlight.
Display Controls
Send bib numbers, split times, or custom text straight to the clock face. Queue entries for rapid sequential display.
One Phone, Many Clocks
Multi-Clock Control
The Innovative Timing Systems mobile app connects to and manages multiple jClocks simultaneously from a single device. A timer can manage an entire course — start line, finish line, mile markers — all from one phone.
Connect to multiple clocks from one phone simultaneously
Synchronize time across every clock on your course
Start together, update together, or control independently
Manage start, finish, and mile marker clocks from a single device
No App Required
Browser Control
The jClock has a built-in Wi-Fi hotspot. Connect to the clock's network from any device — phone, tablet, laptop — and control the clock entirely through a web browser. No app install required. No internet connection required. Just connect and control.
Built-in Wi-Fi hotspot — no router or internet needed
Works on any device with a web browser
Every feature from the mobile app available in the browser
Ideal for volunteers and guest operators
Permanent Installations
Network Control
The jClock can join an existing Wi-Fi network. Once connected, the clock is controllable from any browser on the same network. Ideal for permanent installations — gyms, school tracks, natatoriums, indoor facilities — where the clock lives on-site and staff control it from a desk or phone without needing to be physically next to it.
Joins your existing Wi-Fi network — no special hardware
Controllable from any browser on the same network
No need to be physically next to the clock
Perfect for gyms, tracks, natatoriums, and indoor facilities
Gymnasium
Wall-mounted, staff-controlled from any desk
Track & Field
Always ready for practice and meets
Natatorium

Indoor Facility
Permanent installation, zero daily setup
REST API
Developer API
When the jClock is connected to a Wi-Fi network, it exposes a full REST API. Build custom control interfaces, automate clock behavior, integrate with third-party timing software, or script clock operations for complex multi-clock deployments. Programmatic control over every clock function. Documentation available.
