Palm Biorhythms v3.0 User Guide


Palm Biorhythms allows you to calculate and view the three main biorhythm cycles for you and any number of friends. This guide gives a brief introduction to biorhythms and describes how to use the Palm Biorhythms program.

What Are Biorhythms?

Biorhythms were proposed in around 1890 by a Berlin doctor called William Fliess. Fliess collected statistics from a number of his patients and from these he observed regular occurrences of symptoms such as fevers, disease and even death. He concluded that there are a number of "master internal clocks" that govern the human condition. These clocks move in regular cycles and are all synchronised at the time of birth. These cycles are known today as Biorhythms.

Classic biorhythms have 3 cycles, which are described below. (There are other 'new' cycles that have been devised, which are combinations of the base 3, but I don't deal with these).

Generally when a cycle is high it's good and when it's low it's bad. When a cycle passes from high to low or low to high it passes through a zero or neutral value. This zero condition is termed critical. The theory of biorhythms advise that you avoid performing activities related to a cycle on critical days. Critical days aren't worse than days when the cycle is at its lowest point, they are just different. On low days things may not be going your way but you are aware of it because you are not feeling your best. On critical days you are more likely to be caught unaware, you may think everything is fine and dandy while in reality things aren't. In a way you may be lulled into a false sense of security. When a physical cycle is critical for example, you may cause an accident because of over confidence. Had you exercised a little more caution it would have easily been avoided.

Please note: the details given above are my understanding of how biorhythms work, and may not be wholly accurate. In addition I don't believe there's any scientific basis in biorhythms and see them as a bit of fun, I'd caution anyone trying to read too much into them.

Using Palm Biorhythms

The operation of Palm Biorhythms can be split into the following functions:

Configuring Profiles: Create or modify the details of friends and family.
Graph View: Display a graphical output showing the biorhythm cycles over 13 days (23 days in hi-res version).
Critical Calendar: Display a calendar showing which days are critical over that month.
Critical List: Display a list showing the next 20 critical days for various cycles.
Daily Summary: Display, at a glance, the biorhythm state for multiple people.
Compatibility View: Show the compatibility levels between different people's biorhythms.
Compatibility Bars: Show the compatibility levels between two people in a bar graph.
Exact Age: Find out exactly how old someone is.

Configuring Profiles

A profile is just someone's name and date of birth. Palm Biorhythm needs at least one profile in order to calculate and display biorhythms. Configuring multiple profiles allows you to switch between displaying different people's biorhythm cycles quickly and easily.

When Palm Biorthyms is started for the first time you will be prompted to create a new profile in the Edit Profile dialog as shown below.

New Profile Dialog

Simply enter in a name and date of birth and Palm Biorhythms is ready to be used. If you want to add new profiles or edit an existing one. Select the menu item View -> Edit Profiles, this action displays the Profiles dialog as shown below.

Edit Profiles Dialog

Graph View

Palm Biorhythms has six ways to display biorhythm information. Each of these ways is termed a view. Probably the most useful view is the Graph View, this displays biorhythm cycles plotted 6 days (11 days in hi-res mode) either side of the target date. To display the Graph View, select the menu item View -> Graph. The screenshot below shows the various parts of the Graph View.

Graph View

Most views allow the user to perform the following actions:

If you are using a device with a jog-dial (e.g. a Clie) the following can also be performed:

If you are using a device with a 5-way navigator the following can also be performed:

Critical Calendar

The Critical Calendar shows which days, over a calendar month, are critical. This view can be displayed by selecting the menu item View -> Critical Calendar.

Critical Calendar View

Critical List

The Critical List shows the next 20 days where one or more cycle is critical for the target person. Select the menu item View -> Critical List to display this view. The screen shot below shows the various parts of the view.

Critical List View

Daily Summary

The Daily Summary View shows the values of each biorhythm cycle for all profiles. Use the menu item View -> Daily Summary to display this view. The screen shot below describes the various parts of this view.

Daily Summary View


The Compatibility View displays how compatible one person's biorhythms are with somebody else. To display this view, select the menu item View -> Compatibility. The compatibility calculation depends on birth dates only, therefore the target date is not shown in the compatibility views.

The program supports two methods of compatibility calculation use the menu Options -> Compatibility Mode to switch between these modes. A complete description of how these modes differ can be found here.

Compatibility View

Compatibility Bars

The Compatibility Bars View shows the biorhythm compatibility between two people. Use the menu item View -> Compatibility Bars to display this view.

Compatibility Bars View

Exact Age

This is pretty self explanatory, it shows the exact of the person used in the target profile. To display it select the menu item View -> Exact Age. Depending on your point of view, this may not be pleasant viewing.
