☀Sunny Side Up

Love it!

This is a handy little app. I love the fact that you can assign different colors to each cycle. Biorhythms are a way to understand when it is advantageous to do certain types of activity, according to your natural cycles, which are set at birth. Critical days are when you are most apt to have issues with whatever energy is crossing the middle line. This app shows all of this in an easy to follow format for each day, week, or month. Well worth the download. Would defiantly recommend this app.


Great App

Very conveniently designed, tracks the whole family & preferences allow you to configure to your own tastes. Provides easy to read graph & lists percentages as well. You are able to use arrows to advance the chart for succeeding days ahead. It has been so convenient to have this reference available in just a couple of clicks. This is the nicest Biorhythm calculator I have used. It is perfect for my needs.
