Living with ME/CFS often means working within an energy limit that is smaller, and less predictable, than the one you had before. Spend beyond it and the cost can arrive a day or two later, as a crash.
Pacing is the practice of staying within that limit on purpose — noticing what activity costs you, and spreading it out so you crash less often. Post-exertional malaise, or PEM, is that delayed payback after doing too much. Avoiding it is the whole point of pacing, and the whole point of Pacer+.
Pacer+ is a quiet tool for doing that. You log activities, energy and symptoms in a few taps; it helps you see the patterns and notice when you may be heading past your limit — gently, before the crash, not after.
It is not a one-size-fits-all threshold. Over your first couple of weeks, Pacer+ learns your own energy envelope from what you log, so the picture it gives you is shaped around you — not an average of someone else. Join the waitlist -
A gentle activity, energy and symptom tracker for people with ME/CFS. Built around pacing and avoiding post-exertional malaise.
