First described in the late 1800s, the term biorhythm refers to the rhythmic cycles that affect a persons performance in various areas such mental and physical ability and emotional activity.

Biorhythm Calculator provides a quick and easy way to see a three week outlook based on accepted biorhythm cycles. It stores the last birthdate entered and always opens to the current date so simply launching the app provides up to date information. Convenient controls are provided to look ahead and back a week at time allowing you to quickly assess future and past tasks. The plot length is can be set from 3 to 6 weeks and the plot start can be left, right, or center aligned. Biorhythms can be calculated for any date in the future or past by entering the information directly.

What’s New

Version 1.1.1

Fixed an issue that could cause biorhythms that were center plotted to display incorrectly.

:| needs more….

There is nothing left un charted.

there is no way out of the app. Unless you force quit the app it will stay forever…not cool
there is no "help" or anything so if you do not know what Aesthetic and awareness are talking about or why they are good to know about your screwed…

It is a great start but there are some details missing. if they would add a stop or exit I would feel better about the app and give it a 4 start. If they added some more information for the lay people who would love to know more about biorhythms and how to work with them that would be a 5 start app right now its a 3 star app at best. (I really woud have given this a 2 star but I love that they have the spiritual/awareness/ aesthetic added. not many programs have those so for that I give 3 stars.) With that said Please keep working and adding to this program.

* Primitive graphics.
* Can't save various profiles (birthdates for various people). You must repeatedly enter birthrates and dates to plot.
* Can't change colors.
* Can't resize the tiny window.
* Can't print or export.
* No preferences at all.
* Can't specify birth time of day or time zone.
* Midnight is centered between the vertical lines, which is confusing. The vertical lines between dates should represent midnight, the true division between dates, not the spaces between the lines.
* Overall very poor. It's a MAC (!!) and can do just a little more than this.

**Not** worth $2!

Works well as quick and handy biorythm calc

Quick and simple app that lets you check your weekly biorythms. I am running this on a mac mini hooked up to my television and have no size or resolution issues. Overall, a good app for daily checking of biorythms but limited in advanced features. Would recommend if you're someone looking for simple biorythm app that is very intuitive to use.
