Best for: One-click timers and billable rates
Starting price: $9 per user/month (billed annually)
Free plan: Yes
Pros: One-click timers on web, desktop, and mobile; billable rates and project estimates on Starter
Cons: No native invoicing, so bills need another tool; approvals and profit reports need Premium at $16
Toggl Track keeps the timer front and center, which is why engineers adopt it fast. A developer starts a timer, picks a project and task, and stops it when the work ends, with calendar integrations and a Pomodoro timer for focused sessions. Starter at $9 per user per month billed annually adds billable rates, team reports, and project estimates with alerts, so a lead can see when a sprint is drifting over budget.
The free plan covers a limited number of users with manual and real-time timers, tasks, boards, and personal reports, which suits a solo engineer or a tiny team testing the workflow. Premium at $16 adds labor costs, profitability reports, timesheet approvals, fixed-fee projects, and Jira and Asana integrations, which matter once billing accuracy becomes a client conversation. The main gap is invoicing: Toggl records billable time but does not create invoices, so teams that bill clients need accounting software or another tool for that last step.
