CORE FEATURES
One system, multiple visibility layers.
Human-Friendly Tracking Defaults
Smart defaults reduce overcount and undercount without requiring manual timers or complex setup.
Explainable Audit Timeline
Every counted or excluded interval includes reason codes so developers can see exactly why time moved.
Automatic Cloud Sync Every 5 Minutes
Sessions, ledger segments, heartbeats, quality events, projects, and collaboration data sync automatically.
Canonical Segment Analytics
Daily stats and day audit expose counted and excluded breakdowns so totals stay transparent.
Quality + Collaboration Signals
Debug sessions, build events, diagnostics, meetings, and pair-programming data give richer context than basic timers.
WHAT YOU LEARN
Beyond total hours.
Lync answers practical questions with evidence: which time was counted, what got excluded, and where your focus patterns are strongest.
