I recently tested Tick, a time tracking tool focused on project profitability at https://www.tickspot.com/. Here is my detailed review based on practical usage and research: Tick impressed me with its simplicity for tracking time against budgets. The one-click timer starts instantly from web, desktop apps (Mac/Windows), and mobile (iOS/Android), keeping my freelancing hours accurate without fuss. The budget alerts feature shines, notifying when projects near limits, helping me stay profitable. Real-time reporting and Basecamp integration made invoicing smooth during tests. No API hurts automation, but offline access works well for mobile use. UI feels clean and fast, ideal for agencies. Free trial and tiered plans (from $79/month) suit small teams, though no per-user pricing limits scaling.
