Code Time turns the time you spend in your editor into clear charts and totals. See your day at a glance: total coding hours, your most productive time of day, which languages you used, and which projects you worked on. Look back: 7-day, 30-day, 90-day, and yearly trends. Compare days. See your active streak. Track AI: if you use Claude Code, Cursor, or other AI assistants, Code Time pulls in token usage, sessions, tool calls, and AI-assisted code changes โ so you can see how much your work is actually augmented by AI. Home screen widgets: Today's coding time, this year's activity heatmap, top languages, and recent AI usage โ all updating throughout the day. Sources: Code Time tracks via official editor plugins for VS Code and JetBrains IDEs, plus an agent CLI for terminal-based AI assistants. The mobile app is a read-only companion to your dashboard at codetime.dev. Privacy: We only store anonymized telemetry โ coding times, project names, and language breakdowns. We never read your code. Full details at codetime.dev/privacy. Free to use. Sign in with Apple, Google, or GitHub.
