Five questions worth answering.

Is Pacekeeper a medical device?
No. Pacekeeper is a documentation and training practice — a log, a prescribed cadence, and a companion. Operates under FDA General Wellness guidance (2019). Your neurologist interprets the data.
What does Pacekeeper actually do?
Three things. It prescribes an adaptive run/walk plan calibrated to your individually-targeted cadence (typically 105–130 bpm, per the SPARX2 protocol). It surfaces that cadence during each session with an optional metronome cue. And it produces a one-page report your neurologist can read in two minutes.
What stage of Parkinson's does Pacekeeper work for?
Designed for runners and walkers in early-to-mid-stage PD — anyone who can complete a continuous 10-minute walk without assistance. The plan flexes by your on/off state, not by a one-size-fits-all ramp.
What devices does Pacekeeper pair with?
Apple Watch and Garmin for sensor input. Exports to Strava, Apple Health, and Google Fit so your existing record stays unified.
What happens to my health data?
Yours, always. Pacekeeper never sells, licenses, or shares your data without your written consent. Export anytime. See the privacy notice.
