For the most part, it seems accurate. I like that it has all seven readings when most biorhythm applications have five or even fewer, thus rendering them incomplete. I wish the developer had not changed the colour for the Intuition reading. I love yellow, but the shade selection is so bright and pale, I can hardly read the line on the chart or read the number on the lower area. Please, can you correct this? I would appreciate it.

I actually got a little obsessed and bought, or downloaded, around 10 biorhythm apps. This was, by far, the most dependable and easy to use. I love seeing all 5 metrics, not only the main 3.

The wheel to select birthdate and time of sleep/wake is buggy. I agree with another review about the pale yellow color of the intuition line. It is difficult to read against the background. I’ll try another app because this one was a bit frustrating. To set my birthdate, I couldn’t use the scroll wheel without it a long delay. The scroll-wheel was stopping and resetting itself repeatedly.

if the app gave you some information as to what each of your levels means each day and guidance about what you should aim for and what to avoid so one could navigate every day as smoothly as possible it would get 4 stars... and if there was the ability to get a report about the best way to avoid issues with other members of the "group" on any given day the app would get 5 stars... its cool that you can see more levels than just the main 3, but if you don't know too much about biorhythms or what the numbers mean then you are left still having to search for the significant info
