Biorhythms Calculator 2026

15 Built-in Biorhythm Cycles

• There are 15 built-in rhythms: 4 Primary rhythms (physical, intellectual, emotional, and intuitive), 3 Secondary rhythms (mastery, passion, wisdom), 3 I-Ching rhythms (aesthetic, awareness, spiritual), 3 Intuitive Patterns rhythms (perception, psychic, success), and 2 rhythm averages (primary and i-ching).
• You can easily toggle various rhythms on and off so you see only the ones you are interested in using the Cycles selector on the right side of the window.
• You can easily change the color of a biorhythm cycle using the drop-down color picker on the toolbar.
• As you hover over various biorhythms in the Cycles Selector, you will see a detailed tooltip with cycle's description and other details.

Custom Biorhythm Cycles

Tailor biorhythm analysis to your life by creating any cycle you need - from hours to decades, and even blend multiple rhythms for deeper insights.

• In addition to the 15 built-in cycles, you can define your own custom rhythms that are based on either a specified fixed period or a combination of other rhythms (combination cycles).
• You can create custom (user-defined) rhythms that are based on a fixed period ranging from sub-day periods measured in hours, to mid-length periods measured in days (like primary rhythms), to really long periods measured in years ( NEW up to 9,999 days ~27+ years in duration) - and all with minute-level accuracy. For example you can create a new rhythm with period equal to exactly 15 days, 10 hours, and 12 minutes
• NEWCreate custom composite rhythms (combination cycles) by combining up to 8 cycles in 4 distinct ways - average, minimum, maximum, or median - and uncover hidden patterns.

Individual Profiles

• Profiles represent individual people whose biorhythms you can analyze. You don't need to re-enter someone's birth date every time you want to view their biorhythms. Simply enter it once and save.
• The profiles can be selected, managed, and edited inside a profile selector pane that appears on the right side of the main window. You can easily organize profiles into convenient groups (folders) such as Family, Friends, etc.
• NEWTo ensure precise biorhythm calculations, you can specify not just birth date, but also birth time and birth time zone when creating or editing a profile.
• You can group profiles not only by folder, but also by their gender or zodiac sign. In addition, you can sort profiles by either their name or age. Should the list of profiles become large, you can always easily locate the needed profile by typing in the first letters of the person's name.
• NEWYou can batch import multiple people to add many profiles at once from various sources like Excel or CSV files, or from VCF vCards. A user-friendly grid interface allows you to preview and edit data before saving it in the program.
• You can even assign a picture or a photo to a profile, so you can more easily locate it.

Multiple Side-by-Side Views with Tabs

Design a workspace that works for you: open any number of views, arrange them freely, and compare data side‑by‑side with the tabbed interface.

• You can open multiple biorhythm view tabs and arrange them freely using the Tabbed Multiple Document Interface (MDI) - side‑by‑side, stacked, or custom splits.
• For example, you can have the Graph View on the left side, and the Table View on the right side; or one above the other; or have a triple split - the possibilities are only limited by the free space on your screen.
• Moreover, views don't need to display the same information. You can easily arrange it so that one view shows one person's biorhythms, while another view shows another person's biorhythms right next to it.
• Just as well, it's possible to show biorhythms of the same person or people in both views but for different time periods, allowing for easy comparison.

See Multiple Profiles in One View

Compare up to five people at once: add or remove profiles with a simple Ctrl+Click and view all rhythms side by side.

• In addition to dedicated Compatibility View, you can easily compare biorhythms of several people in various views by selecting several profiles in the Profile Selector.
• Normally, when you simply click on a profile in a profile selector, this will change the profile displayed in the active view. However, if you Ctrl+Click on a profile, it will add that profile to the active view (or if you Ctrl+Clicked on an already selected profile, it will be removed from the active view).
• On the screenshot you can see an example where the Graph View shows biorhythms for two people and then for 4 people. However you can see biorhythms of up to 5 people in this fashion, and not just in the Graph View, but also in most of the other views like Table, Calendar, and Timeline.

Plan your Day with Biorhythm Activities

Take time planning to the next level and let biorhythms inform your decisions! With the Activities feature, you can plan your day with biorhythms: define activities that trigger when your biorhythms hit the right thresholds and let the app show you the best times for them.

• Activities make it very easy for you to learn the best time to perform certain actions (or the time during which you should avoid doing certain actions). For example, you can define a certain activity in the program that should only be triggered when Physical and Emotional rhythms are above 5%.
• You can then see when you should engage in activities in various views: like Graph NEW, Timeline, Calendar, Report, Threats and Opportunities, and others.
• Compare that to what you'd have needed to do without such a feature. You'd have to manually scroll through long biorhythm charts, looking for days when the rhythms are above or below certain thresholds. That would take hours! With the activities feature, it takes you mere seconds!
• This unique feature is available only in Biorhythms Calculator, and you won't find it in any other biorhythms app!
• You can even export activities to iCalendar format or Microsoft Outlook, so you are automatically reminded about them ahead of time!
• You can use up to 6 different rhythms in activity definition, specifying the range of desired values for each e.g. 25% to 100% with ability to invert it NEW, i.e. -100% to 25%.
• There is no limit to how many activities you can define, and activities can be grouped into folders for easier management.
• NEWYou can even designate some activities as "threats" so they will be presented with a different style throughout the app, alerting you to the fact that these represent time periods you need to be careful of.

Save Information & Export Data from Views

• You can easily save most views or information from them in common file formats for easy sharing and interoperability with other applications.
• For example, biorhythm charts from Graph and Chart views can be copied to clipboard, or saved as *.pdf-s NEW or images like *.webp NEW, *.jpeg, *.png, *.gif and others. This way you can easily share or e-mail biorhythm charts to your friends, or insert them into documents.
• NEWKey biorhythm data like critical days, max/min days, phases, and activities can be exported to iCalendar Format from Timeline, Calendar, Threats and Opportunities, and other views. You can then import these *.ics iCalendar files into most calendar applications like Microsoft Outlook, Google Calendar, Apple Calendar, and others. This way you can easily keep track of your biorhythms and automatically receive reminders about events ahead of time!
• NEWTable-based views - Compatibility, Overview, Table, Threats and Opportunities, and Journal - let you copy to clipboard or Microsoft Excel as well as export displayed data in tabular formats like *.csv files.
• NEWDetailed biorhythm reports generated by Report and Text views can be saved as html web pages or text files (*.html, *.txt) to be easily viewed in any browser, published online, or otherwise preserved or shared.

Navigate Your Biorhythms with Ease!

Navigate your biorhythms like a browser: jump forwards or backwards, zoom, and even play your chart in real time!

• Use Ribbon Navigation Tab to change dates, durations, and other settings. As you move your mouse over them, small tool tips will appear with explanations, thus making it very easy to learn all the functionality.
• You can easily navigate forwards and backwards in time as well as zoom in/out using mouse scroll wheel in Graph, Chart, and other views!

• The program remembers your actions, like changing the view, changing the start date or duration, etc., and saves them automatically into navigation history, so you can easily go backwards and forwards – much like you do in a web browser.
• AutoNav feature lets you "play" your biorhythms live by automatically shifting calculation date either forward or backwards at a set speed, allowing you to see your biorhythm chart come to life with real-time animation!
• What’s more is that the program is very precise: you can specify dates and time intervals to the last second (while in other apps the smallest time unit is equal to one day).

Visualize Your Biorhythms

• Read your biorhythms at a glance by checking various visualizations - graphic symbols that represent your biorhythm status in most views. These consist of graphic icon sets that represent the biorhythm value, and trend indicators NEW that represent cycle trend.
• With graphic icons you can easily tell how well you are doing “biorhythmically” by looking at the icon. When your biorhythms are low, depending on the icon set you selected, you may see sad faces, stormy clouds, red flags, etc. If your biorhythms are high, on the other hand, happy faces, green check-marks, etc will be displayed instead.
• NEWTrend indicators provide even more information as you can see whether you are on the rising or falling trend. Additionally critical, zero, maximum, and minimum days get their own unique symbols, making it easier to notice them.
• There are more than 30 different icon sets to choose from, and you can even make your own icon sets easily using built-in editor!
• Visualizations appear not only in the various biorhythm views (like Table View, or Report View), but also inside mouse-over tips, as well other User Interface elements.
• If you do not like visualizations, you may turn them off completely, so that only numerical value that represents your biorhythm status is displayed.

See Contextual Biorhythm Details

• Dive deeper with interactive views: the info panel and live tips reveal detailed biorhythms information, allowing you to examine a particular time point in depth.
• For example, Info Panel at the bottom will show biorhythms details for the currently selected time point in the view, and as you change the active time point, it will be updated accordingly with NEW icon animations showing the trend.
• The bottom Info Panel includes profile details such as name, time of birth, current date / time information, lunar phase, and of course a snapshot of biorhythms at the selected time point. NEWIt can also show biorhythms statistics for a chosen time period.

• NEWThese live tips can furthermore be pinned so they remain accessible even after you moved the mouse away from the biorhythm time point.

Intuitive User Interface to Explore Biorhythms

• Intuitive User Interface makes it very easy to use the program.
