FAQ

Questions people ask

What life tools are available?

NovaKit Life includes date and time calculators, stopwatch, Roman numerals, postal lookup, pregnancy and health reference tools, loan calculators, world time, and exchange-rate utilities.

Are health calculators medical advice?

No. Pregnancy, fetal weight, child height, BMI, and life timer tools are reference calculators only and should not replace professional medical guidance.

Do exchange rates update automatically?

Exchange-rate tools request current rates from a public API at runtime. If the provider is unavailable, the tool shows a clear error instead of using stale values.
