Yes, parts of the Toggl Track web app can work offline (for a limited time). Here are a few key things to keep in mind:
Offline mode will be automatically enabled whenever you’re not connected to the internet.
Offline mode entries will have a warning icon with an exclamation mark in front of them in List-view. This signifies they have not been synced to our servers yet as they were created offline.
All data you create or update offline will be synced with our servers once your connection is restored.
Offline mode is only available for time tracking. In other words, it only works on the Timer page. Reports, Project management, Profile settings, etc. are not available offline.
If you still have questions about using Toggl offline, please contact our Support team by clicking on the purple chat icon in the bottom right corner of this page to start a chat or search our knowledge base.
