### 1/5 — Poor

*2025-12-23*

How do I use this for 12 people. 🤷🏼‍♀️

### 5/5 — Good App!

*2022-01-15*

Always gives a good chart! Very flexible, gives you something to think about!

### 3/5 — Lost the vertical grid lines in iOS upgrade

*2019-10-21*

Hoping an upgrade will match most current iOS version? Hard to view without the grid and dates now. 😞

### 1/5 — The date

*2018-07-18*

The date is set for 2561, even on the copyright. How do I change that?

### 5/5 — 심플하고 깨끗한 앱

*2018-04-21*

재미로 보는 하루의 바이오리듬

### 1/5 — Simple Design/Outrageous Cost/Flawed Programming

*2018-03-13*

Not worth the two bucks you pay.  Got it to crash within the first 5 minutes of having it on my iPad.  

Lack of instructions either in app or on developer website is a huge detractor.  That’s why it took me five minutes to crash it; had to figure out how to add people, DOB and then page/scroll through their names both slow and fast.

Crash it by selecting “slow” so that it rolls pages into view rather than scrolling from left to right.   Just flipping back and forth between people in the slow mode caused the graphics to disappear and crash the app.  Had to restart th app to get it to go again.

Developer has lots of work to do to make this as good as a bottle of “$2 Chuck”.

### 2/5 — Hard to read dates

*2017-10-12*

Please darken the font color on the dates.

### 4/5 — Fast gut

*2016-10-17*

Beschriftung von Datum und Kurvenbezeichnung könnte etwas größer sein. Desweiteren wäre eine Auflistung der eingegeben Namen zur direkten Anwahl wünschenswert.

### 5/5 — nice view

*2016-06-16*

awesome and simple design. 간결하고 좋아요

### 4/5 — Simple and actually pretty elegant

*2016-04-15*

Nice interface, smooth transitions and original way to set date. Can have a white (like pictures) or a black background. Free version comes with ads but very small, which is a plus. It has the original 3 theories, not several unknown others like some apps. Other than that it looks pretty cool, very nice use of color on the white background, I like it a lot! And it's clean, there's somewhat of a hidden menu on bottom of screen with simple iPhone icon (three dots). 

Pretty hard to not understand these super simple functions!!!

Why 4 stars? -I haven't checked it with the actually theoretical equation. -The full version just lets one save dates, albeit it's more save slots than the competitor, why no save function? And if I did buy it, why not idk 99 saves? Or infinite saves? Seems silly to charge for. 

But those are honestly the only reasons. It's a great app for what one is looking for in a biorhythm app.
