  Install Chronojump on Windows

Recommended
  Recommended: Chronojump 2.3.0-2423 (2025 Mar 12).

Please, read this first:
  • Your Windows have to be 64 bits, check it previously.
  • Installed Python version is not compatible with Windows 7 and previous Windows versions. Python is only needed if you want to import sessions from other Chronojump databases.
  • In the following weeks we will have also an ARM version.
Older versions

Older version: Chronojump 2.3.0-83 (2024 March 25)

If the language of your system is hebrew and you cannot run the software, please contact us.
 
On Windows it works on both PCs and tablets, but does not work on Win 8 RT, Windows 10s, Windows 11s because these systems only allow apps from the Microsoft Store.
 

  Install Chronojump on MacOS

Recommended
  For Silicon mac (arm64): chronojump-2.3.0-2517-arm64 (2025 Apr 5)
This version should capture with encoder flawlessly if R is installed (see Notes below).
  For Intel mac: chronojump-2.3.0-2305-x64 (2025 Feb 16)
Needs MacOS version Mojave (10.14) or higher.

Notes:
  • Before install you need to check if your mac is Silicon or Intel. If unsure read this.
  • R is used for encoder capture and some graphs analysis on force sensor, encoder and race analyzer. If any of these processes fails, we recommend you this workaround:
    1. Install R for mac Silicon, or R for mac Intel.
    2. On Preferences / advanced / R, Python. Rscript file -> [Other location], and click on [Autodetect].
      If you have installed R and Autodetect does not work, just write: /usr/local/bin/Rscript below [Autodetect].
    3. Close preferences and restart Chronojump.
  • Python is used for session import. If this process fails, we recommend you this workaround:
    1. Install Python for mac (works for Silicon & Intel).
    2. On Preferences / advanced / R, Python. Python file -> [Other location], and click on [Autodetect].
    3. Close preferences and restart Chronojump.
  • If you have Chronojump data in your computer, better do a full backup of Chronojump data before installing.
Older versions
Installation procedure for older versions:
  1. Install mono.
  2. Download Chronojump for macOS:
      Chronojump 2.3.0-83      (9 Apr 2024)
      Chronojump 2.3.0-83 for Sonoma (temporary fix without graphs) (9 Apr 2024)
  3. Allow Chronojump on Gatekeeper
  4. If this is the first time you install Chronojump: Install R (and you will also need to accept it on Gatekeeper)
If you cannot open the Chronojump-version.dmg file, try to right click on the file, select: “Open with” > “Disk Image Mounter”.
We’ve detected that Suunto users can experience conflicts with Chronojump. Please make sure that Moveslink software is not running during Chronojump use.
 

  Install Chronojump on Linux

Download recommended
  For X86-64: chronojump-2.3.0-2399-gbf08d_x64.deb (2025 Mar 10)
For ARM64: chronojump-2.3.0-2411-g0f6ff9_arm64.deb (2025 Mar 11)
Download advanced
For advanced users:
Hardware permissions
If this is the first time you install Chronojump:
  • Assign permissions for the hardware:
    sudo usermod -a -G dialout username
  • Close the session in order to ensure that hardware permissions are assigned
 

  Install Chronojump on ChromeOS

  For X86-64: chronojump-2.3.0-2399-gbf08d_x64.deb (2025 Mar 10)
  For ARM64: chronojump-2.3.0-2411-g0f6ff9_arm64.deb (2025 Mar 11)

To know which I need you can install: Cog – System Info Viewer and see what it says on “Architecture”.

  Microcontrollers

Our microcontrollers provide the bridge between the sensors and your computer.

Jumps and encoder test are measured by our microcontroller Chronopic.

On WICHRO, Force sensor and Race Analyzer we use other microcontrollers also designed and manufactured by us (and included in the products).

  Webcam recording / sync

Chronojump can record any test using a webcam. But users need to understand:
  • Chronojump does not manage the webcam directly, it does so through the ffmpeg utilities that Chronojump installs and uses for this purpose.
  • New versions of Chronojump sometimes come with updated ffmpeg utilities to help detect new cameras.
  • We do not sell webcams and since you provide your own computer, we cannot ensure that your webcam will be recognized by ffmpeg on your computer.
  • Most of the hardware should work and you can contact us to try to find a solution. But we can’t ensure that there is a solution because the problem will be more related to your operating system or ffmpeg detection.
  • If the camera doesn’t start, the first thing to do is make sure Chronojump (and maybe ffmpeg) have camera recording permission. Check it on your operating system.
  • On ARM-silicon Mac versions it might be more difficult for the camera to work properly (some of the reasons).
  • Starting with version 2.3.1, Chronojump will have a playback video synchronized with a moving mark in the test performed on the Force sensor and in Race Analyzer. Please note that this synchronization is not perfect, but it will be very useful and it is a long-awaited feature for our users.
