What aimy.bio can do

A free biorhythm calculator built on Dr. Jerzy Sikora’s 1983 method — with everything computed in your browser, not on a server.

• Your three cycles today

  Three rings — physical, emotional, intellectual — with the day’s symbols (+, −, X, 0) and where each cycle is heading. One glance and you know what kind of day the method sees.

• Key days calendar

  Transition days and strong-phase starts, 90 days ahead. One tap exports them as an .ics file to your phone or desktop calendar — no account, nothing leaves your device.

• Phase charts

  Sikora’s method reads cycles as discrete phases, not a smooth sine wave. The charts show exactly that — including the emotional cycle’s famous double critical day.

• Compatibility for two

  BioMatch compares two people’s cycles the way the 1983 book did — bioaffinity cycle by cycle, phase by phase. Check a partner, a friend, a teammate.

• Family view

  Up to ten profiles side by side: whose day is strong, who’s in transition, where the collision days land. One calendar for the whole household.

• A blind diary — and a real study

  Rate your day before you see the chart, so the score can’t be suggested. Your entries power an honest, pre-registered test of whether the method holds up. Join in, anonymously.

• A share card, not a screenshot

  One tap renders your day as a clean PNG — cycles, symbols, no name, no birth date. Safe to post anywhere.

• A real app, offline

  Install it from the browser and it works with no connection — on iOS, Android and desktop, in eight languages.
