BioCalendar: Daily Biorhythm

Your cycles and critical days

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Three cycles counted from your birth date, a written reading every morning, and every critical day in your calendar. New subscribers get seven days free. BioCalendar counts your three biorhythm cycles from the day you were born and gives you a written reading for every day. The physical cycle runs 23 days, the emotional 28 and the intellectual 33. Each passes through the same eight states, from its high through a critical day to its low and back. Where the three sit today chooses one of 512 written readings. Read yours in the morning, then notice how the day feels against it: a few minutes of reflection, every day. WHAT YOU GET • Today's reading, and the reading for any date, past or future • A calendar with every date's symbols and critical days • A daily notification at the hour you choose • Goals, with the stretches of the month that suit each one • A monthly set of readings written around your goals and your "About you" answers • The key to every symbol, and a Help Center inside the app WITH PLUS • A personalised reading written for you every day • The Companion: ask about your day or your week, in plain language FAMILY PLANS • Up to five people on one subscription, each with their own login • Compare days: see, cycle by cycle, where your rhythms fall in step with each other • Family Plus adds personalised readings and the Companion for everyone in the household PLANS AND THE FREE TRIAL Core and Plus are for one person; Family and Family Plus are for up to five. Every plan starts with seven days free for new subscribers. After the trial the plan renews automatically, monthly or yearly as you chose, and your Apple ID is charged at the start of each period unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel in your Apple ID subscription settings; you keep access until the end of the period you have paid for. YOUR DATA Your date of birth is the one thing BioCalendar needs, and it never leaves our servers. The personalised and monthly readings and the Companion are written with an AI provider, and only if you allow it; your name, email address and date of birth are never sent to it. You can delete your account, and everything in it, from Settings. WHAT BIOCALENDAR IS Biorhythm theory is not supported by scientific studies, and BioCalendar does not claim otherwise. For educational, informational and entertainment purposes only. Not advice, and not a prediction. NEW IN VERSION 3 BioCalendar 3 is a new app, built from the ground up.
