Prosty biorytm obliczy twój biorytm na kolejne dni.

Prosty biorytm obliczy twój biorytm na kolejne dni. Algorytm biorytmu rozpoznaje trzy cykle: fizyczny 23-dniowy, emocjonalny 28-dniowy i intelektualny 33-dniowy. Każdy z nich został szczegółowo opisany wraz ze wskazaniem na jakie umiejętności dana linia wskazuje.

Według zwolenników biorytmów, na życie człowieka wpływ mają rytmiczne cykle biologiczne, definiujące bieżące zdolności w różnych dziedzinach aktywności. Cykle te zaczynają się tuż po urodzeniu i oscylują w stałym sinusoidalnym rytmie przez całe życie. Znając datę urodzin człowieka, przy użyciu modelowania matematycznego, można zatem przewidzieć jego poziom umiejętności z dokładnością do jednego dnia. 

W aplikacji znajdziesz m.in.:
- Trzy linie biorytmu - fizyczną, intelektualną i emocjonalną,
- Czytelny wykres biorytmu na następne dni - wszystkie trzy linie i każdą z osobna,
