PaceBar

Low-impact sensing - reads timing and frequency of interaction events without recording typed content or screen data, Steady modeling - local modeling turns working rhythm into a quiet menu-bar readout, Adaptive baseline - learns individual working rhythm over time instead of using generic thresholds, Small prompts - only nudges when useful, not distracting, Use the headroom - protects next block for important work when load is low and focus is stable, Reset briefly - nudges to step away for a few minutes when session gets heavy, Made for parallel work - helps see when extra parallelism from AI tools starts raising pace, Private by construction - no accounts, no telemetry, no cloud processing, all data stays on Mac

Helps knowledge workers notice when their work pace is rising, especially when using AI tools and parallel workstreams that increase pace and workflow fragmentation.

Mac users, knowledge workers, people running multiple AI-assisted threads simultaneously who want to maintain awareness of their work pace without intrusive monitoring.

Measuring interaction intensity and work pace, Protecting focus for important work when load is low, Knowing when AI-assisted parallelism is raising pace, Taking breaks when workflow gets fragmented

One-time purchase or subscription via Mac App Store

Privacy-first local-only processing with adaptive baseline that learns individual rhythm. No data leaves the Mac. Not a generic threshold-based tool.

AI tools make it easier to run several threads at once, increasing the need to track when that extra parallelism starts raising work pace.
