Personal Biorhythms Calculator

I enjoy using this APP daily or every other day; the information is pretty darn accurate, scary accurate. Definitely, a must have if your into this kind of stuff!!!

One way that it could be better would be a feature that found the next double and triple days. Also, a search for the best day for a couple to get together

Like to keep in mind when I'm apt to be accident prone!

I BELIEVE YOU BIORHYTHM CALCULATOR IS INVERSED TO ALL THE OTHER PROGRAMS AND WEBSITES. For example. Inverse your + / - to get your correct reading.

I've found myself at the level it predicts almost every day.

Could not be any easier. Much better than the pencil and paper method you used to have to do.

How fascinating! If in doubt check it out.

and can' t change the initial settings

Listen carefully. You will hear the sound of your own heart! Teaching and guiding you to your best life. All you ever had to do was stay by me.

But I wish the 4 colored lines (waves) were thicker.

PLEASE HELP...WILL CHANGE TO 5 STARS ASA MY WIDGET WORKS AGAIN! It recently stopped updating, so I removed it, put it back and now I can't even get it to accept a new user. I USE THAT WIDGET EVERYDAY AND LOVE THIS APP SO MUCH - PLEASE FIX OR TELL ME WHAT TO DO!

Update (12/25/16) Is it possible that on your next UPDATE for the app that you make the EMOTION line Darker and ALL the lines thicker, or make it an option in the settings. Thank you. (Original comment)soooooooooo far so good. Really like the prediction portion, many of the others leave it to you go figure out, if what you physically are feeling is right. Like that break down.

If it would show me a comparison chart (all on the same page) between my biorhythm & that of whatever other individual whose name & birth date I enter, I'd give this app 5 stars. Otherwise, it's average, no better than any other.

OK friends, please try this at home - obtain your biorhythm from any of the other websites or apps. OK, now calculate your biorhythms on THIS site and be sure to put a check in the box to select "Use more precise algorhithm". It comes right after you input your name and birthday. Now compare. Changes everything - compatibility, peaks, critical days, etc. Thank you! Why would anyone want less precise and likely inaccurate results?

I really enjoy the biorythmn predictions and day cycle insight. The compatibility with others is awesome. But, I may suggest an update to incorporate the time of your birth. I've use another biorythmn app uses that option, my biorythmn comes up completely different. Looking for a more Accurate representation with birth time.

The program is showing my physical curve at the very top. I compared it with seven other similar programs all of which show my physical curve to be at the very bottom. Some of the other curves are wrong also. Rubbish.

This is a well-designed program for biorhythms tracking and is very accurate in each of the categories displayed. My personal experience, after I notice a lower​ or higher energy like feeling, more sensitive than normal and then I check the biorhythm software for the peaks and valleys, typically I am within 3 days of one.

Most accurate biorhythm app I've used to date. Even dealing with a language barrier (I believe the dev may of Russian descent) the descriptions & suggestions are quite easily deciphered grammatically. Was a horoscope nut for decades but nothing coalesces better for me than biorhythm and this app with its screen friendly adds (never drawn over info & some of the easiest to look past) is one of the most user friendly in the app store and the most comprehensive for the awesome price of FREE for this version.

I think it is great but seems like the mental cycle and the emotional cycle are not scientifically based. The question is that where do the 23 day period and 33 day period come from? It may not be accurate.

Quite interesting but not enough explanation of what it all means. Also the English is appalling.

Informative and accurate. I am continually amazed when insights occur to me about a situation, then I look at my biorhythms after the fact to find that my intuitive abilities were peaking, for example. Four stars instead of five only because the language in the text portion isn't always clear.

The app is fun. The problem I have is that there are many grammatical errors. Hopefully, future updates will address this.

Very inaccurate when I checked a couple years ago. i think the algorithm is incorrect. Checked again today and it's still way off. I don't recommend.

How can an app that is this inaccurate (its output trails actual computational results by over a week!) be so well-reviewed? And how do you inject such an offset error into a sine wave calculation? It's not exactly a difficult formula, either, sin(2πt/c) where t is the number of days since birth and c is the length of the cycle (23 days for physical, etc.). I know it's possible to do this accurately on Android because there are some apps that perform properly, but this isn't one of them, and all of you how are giving this app a five-star rating have failed to verify the results against a calculator.

Love the ability to check compatibility with others. Also like that and includes intuition which I have not seen her most by Rhythm charts.

Uncanny.

Not a bad app. It is a bit difficult to see exactly where everything is, but maybe they will improve as updates are done. Still, good app.

Love the description! (unlike another that gives bar graphs, and nothing else.) Seems to have me pegged pretty well, after 2 weeks use.

It's nice to know when I feel good, bad or indifferent where my biorhythms are... I use it for my family too.

Clean, simple, easy to understand. I agree with what someone else already said.... the rythm lines need to be more bold. Also I would happily pay to remove the adds from this app. Overall very pleased

A highly informative and precisely accurate biorhythm prediction application. Easy to use and understand without any obvious issues with the programing..impressive!

I Love This app.... When I feel a negative Or Postive way I run to This app to c what I'm to work with for the next couple of days!

Best biorhythms app out there so far. I especially like the compatibility checking feature you enter 2 birthdates and it will calculate your compatibility with that person. Good job makers keep improving it.

Very very much better that using a paper back like I did so many years ago.

I started with biorhythms back in 1977 with the 23, 28 & 33 day templates and a book to determine where you were in the cycle. Compatibility's were even more difficult. This app is great at it all, much easier to explain biorhythms to someone who does not know anything about them, thank you.

Easy interface and options without complexity. Some category explanations seem redundant but for the most part accurate to my perceived moods and temperaments.

Cool app! Easy interface.

Significantly more accurate than other biorhythm apps I've tried.

Very well for me ,I had use biorythm for a long time

Most accurate biorhythm app I've ever used
