Tracking · hypothesis-support
A two-interval clip-on timer for fetch blocks and mandatory rests.
A dead-simple timer that holds two intervals, work and rest, and buzzes on your belt so the rest block actually happens. It enforces the discipline you already chose; it does not invent the ratios. Splash resistant rather than waterproof, so keep it off the swim.
Job bucket: hypothesis-support
Does not prescribe work-to-rest ratios and does not predict anything. Not medical advice.
When it fits an active hypothesis, a love-move you already named, or you ask. Never as a cure.
