Web development is built on deep focus, interruptions, and problem-solving, not clean time blocks. Tools like Harvest assume you�ll remember to start and stop timers perfectly or reconstruct your hours later. Tympi is built for how developers actually work. With its floating Picture-in-Picture timer, developers can track time while coding, debugging, testing, or deploying without switching tabs or breaking flow. Every session is logged in real time, reducing missed hours and billing inaccuracies. Tympi lets developers track time against specific projects and tasks, so work is always tied to real deliverables. Debugging sessions, refactors, and last-minute fixes no longer disappear into �miscellaneous� time. Compared to Harvest�s time-first approach, Tympi connects time ? project ? invoice in a single system. Once work is complete, developers can convert logged hours directly into invoices without manual entry. This eliminates disputes and creates clear, defensible billing for clients or engineering managers. Tympi also supports both hourly and project-based billing, making it ideal for freelancers who switch between retainers, sprints, and fixed-scope builds. Instead of spending time managing spreadsheets or separate tools, developers get one system that respects focus, accuracy, and professional billing.
