Personal Biorhythms Calculator Customer Insights

1. This is a good biorhythm app.I've been using this Biorhythm app for years now, and I've found it to be highly accurate.

2. (Don't we all need that?!?)I've just downloaded 3 more biorhythm calculator apps (even checked a Japanese site), and found that this is completely on the opposite scale.

3. Concise and to the point information, graph is easily understood, very well put together.It seems to be quite accurate and easy to use.

4. The reason I try not to is a prediction can be self fulfilling! Years ago I bought a mechanical one - like a circular slide rule for those of a certain age! That checks out accurately with the maths of the cycles, though the analysis is not as thorough as I would like.

5. Please recalibrate your app.Downloaded 4 "biorythm apps with the highest rating into 4 seperate devices and then all on the same device together and then deleting the others so only one at a time was on the device.

6. Silly as this may sound but so far it has been very accurate within a day or two.Used Samsung Smart Switch to move to new phone.

7. Everybody shows -88% on my physical but yours is saying that I'm on +96% ; plus my headache doesn't feel positive at all.

8. Doesn't ask for unreasonable permissions like location or app usage, physical usage etc... (very honest).

9. I'd like it better if it gave more detailed information and maybe had some tools to help me benefit from the info.Easy to see the chart, easy to read the information.

10. Other than that it is a useful and apparently rather accurate representation of the three basic cycles that take place each day.

11. I don't know if biorhythms are accurate anyway, but this one doesn't seem to come anywhere near close.
