About ToffeeLab

Start with an everyday question

ToffeeLab is a solo-operated collection of tools and explanations for Saju, baby milestones, and investment planning. We aim for simple interactions and clear calculation methods.

Different kinds of evidence

Saju is traditional interpretation for reflection. Baby tools help explain dates and official growth references. Investment tools calculate user assumptions. None guarantees a diagnosis or future success.

What is currently available

Investment simulations, baby date calculations, Saju charts, comparisons and daily reflections are available. Growth percentile calculations are not provided. Check each tool’s calculation method and supported range. The service has not been reviewed by medical or financial experts.
