TimerOS is our product, so this is not an independent review. Every fact about another company was read off that company’s own pricing, security, trust-centre or legal page on 12 August 2026 and links to it. Where something could not be verified, the page says so. Each comparison ends with a section on where the other product is the better buy.
Automatic tracking runs in the Windows app; the macOS build is in development. Everything else runs in the browser.
14 days of the full plan, with nothing locked. Your card is saved at signup and is not charged if you cancel before the trial ends. If you stay, you pay from €8 a month for one person or €15 per user, billed annually. Full pricing.
For freelancers and for teams of two to fifty. Larger organisations need Enterprise, which is in early access.
