Pace

Printable plans built from your own numbers.

Pace is our own family of four small stores. Each asks a few questions, then code turns the answers into a personal PDF plan, dated from the day you start: training loads, maths sheets, Bible readings or exam study days. No templates, no subscriptions, one payment.

All four are open for orders. Set up a plan on any of them and the PDF is ready within minutes of paying.

Four stores

One engine pattern, four subjects. Each store has its own design, its own languages and its own reader.

How a plan is made

The same three steps in every store.

  1. You answer

    A short set of questions: the goal, the dates, the numbers that only you know.

  2. Code calculates

    Paces, loads, sheet levels, reading lengths and study days come from formulas and published formats, not from AI. Kilopace alone adds AI-drafted coaching notes around the calculated numbers.

  3. You print

    A PDF arrives by email within minutes, every page dated, ready to print at home.
