PaceClock, a swim coach with guardrails

Field notes

PaceClock describes a three-way intake: per-length data from FORM goggles, distance/time/heart-rate data from another source, or a thirty-second manual log. At the end of each week it produces a review and proposes the next week under explicit limits, including heart-rate ceilings, minimum rest, progression caps, and deloads. The page says cards are arithmetic-checked, formatted for a wet phone, and convertible into text for FORM goggles; the extracted homepage does not show the underlying interface.
