Running multiple time tracking timers simultaneously for different projects or clients.
Concurrent timers are multiple active time tracking timers running simultaneously — each logging to a different project or client. Most time trackers only allow one active timer: starting a new timer stops the previous one. Concurrent timers remove this constraint.
The need for concurrent timers arises when you legitimately work on multiple things at the same time. Common scenarios: two browser windows with different client codebases open, a working session paired with an ongoing client call, or administrative work running in parallel with billable development.
Concurrent timers are particularly useful for developers using AI tools. An AI-powered coding session for Client A might run in parallel with a background process or deployment monitor for Client B. Stopping one to start the other loses accurate billing data.
Not all time trackers support concurrent timers — Clockify, for example, stops the previous timer when you start a new one on the standard plan. This forces users to reconstruct parallel work manually.
In ClockMe
ClockMe supports concurrent timers on the free plan. Start as many timers as you have active projects — each runs independently and logs to its own project. The dashboard shows all running timers with live elapsed times. You can stop individual timers independently or stop all at once.

Many consultants legitimately work on two things simultaneously — a deployment running in one terminal while writing documentation in another, for example. Concurrent timers let you track this accurately and be transparent with clients about how time was allocated.
No. Most time trackers (including Clockify on free plans and Toggl Track) stop the current timer when you start a new one. ClockMe supports concurrent timers on the free plan — no upgrade required.
Each timer logs to its own project and generates separate invoice line items. If two timers run for the same hour, that hour appears on two different project invoices — which is correct if work was genuinely split between two clients.
