About this tool
A simple browser time tracker for the current session — type what you're working on, click Start, and click Stop when you're done to log it. Track as many tasks as you like and see the running total. Nothing is saved or sent anywhere — closing or reloading the tab clears the list.
Type what you're working on, click Start, and click Stop when you're done — each task is logged with its duration and added to a running total, entirely in your browser.
Why use Tabreon for this?
No account or setup — name a task and click Start to begin logging time immediately.
Track as many tasks as you like in one session and see the running total update automatically.
Nothing is uploaded or stored on a server — the list lives only in your browser tab.
How to use the time tracker
1Name the task. Type what you're working on into the task name field (optional — it defaults to "Untitled task").
2Start. Click Start to begin timing that task.
3Stop. Click Stop when you're done — the task and its duration are added to the list, and the total updates.
What is an online time tracker?
A time tracker logs how long you spend on individual tasks by starting and stopping a clock for each one, then keeping a list of every task alongside its duration and a running total. It's used for freelance billing estimates, tracking focus time, or simply seeing where a work session actually went.
How Tabreon handles your data
Every task and duration is kept in memory in your browser tab for the current session only — nothing is saved or sent to a server, and reloading or closing the tab clears the list.

Common mistakes & limitations
Entries are session-only and not saved — reloading or closing the tab clears the list, so export or note down totals before leaving the page if you need to keep them.
