System Requirements

Boat Timer is a PWA or “progressive web app”. It is essentially a web page that can be installed and used as an app, including being used with no internet connection. So its platform is a browser and it has been extensively tested with the Chrome and its open-source cousin Chromium. Firefox and Safari should also support PWAs and we hope to test them soon. A very recent version of browser is the most important requirement for Boat Timer.


Boat Timer can be used with touch-screen displays or with normal laptop screens and monitors (using a mouse).

Internet Connection

Required when signing on the first time, or when changing accounts after signing out. Not required when timing a race or producing results.

For the Cloud Service, an internet connection is required when you want to upload progress and results information, but not to time races.
