1. Another option would be great to have the compatibilities graphs to be superimposed over each other so I know when that particular person is more approachableSo far so good, although I would prefer a little less dry content and more detailed description of the personality of each category and how it pertains to each individual and, or profile.

2. Thanks for making a simple, easy to use app without all the intrusive, full-page ads others must include.UPDATE: The BEST biorhythm cycle app I've found to date.

3. Sometimes the description will say trending one way, while the graphs clearly shows the oposite.For the first couple of months I feel that it was very parallel to how I felt.

4. Special attention is given to critical days in the forecast which I believe is an extremely 'life or death' consideration feature.

5. But watching for critical days has helped the intergenerational family know what to expect and tread lightly if needed.

6. It offers much more than just the 3 typical biorhythms - this app identifies other important rhythms such as, spiritual, intuition, awareness etc.

7. I use it everyday.Read advice on another user & was able to get calendar date entered correctly.
