### 3/5 — Can’t see day number at the top

*2025-04-23*

On the iPhone 15 you can’t see the day number at the top of each day it’s cut off. But otherwise this has already been more helpful than my Creighton instructor on learning what to write each day!

### 5/5 — Best app for NFP!

*2024-03-08, version 2.1.5*

Thank you for developing this app for NFP! It is so convenient to not have paper charting!

### 4/5 — Good for Creighton Model, not user friendly

*2023-11-05*

I like this app for charting, but I wish there was an option for it to show the dates in calender view when you show multiple cycles together. I also wish there was an insights tab where it shows how the cycles compare to each other. Otherwise, it is very helpful.

### 5/5 — The best!

*2023-06-29, version 2.1.5*

This is better than paper charting! Flexible, easy to use, and simple. I love it!

### 4/5 — User friendly

*2023-02-27*

Great alternative to paper charting. Please update to allow for multiple colors ie BC or PGY. Currently you can only choose one which is limiting. Thanks!

### 5/5 — Wonderful App for Creighton Method Tracking

*2021-12-19*

I love having this app available to assist with tracking my wife’s cycle. Our son sleeps in our room and is a very light sleeper, so it was very inconvenient to try tracking via paper at the end of the day without a light. My wife and I are able to consistently track her cycle with ease using this app. I do wish we could sync this app between our phones, so she could see the chart in real time - possibly if we could have a shared account for her to long into when needed?

### 4/5 — Glad there is an app

*2021-08-31*

So glad there is an app for Creighton charting. Two things I have on the wish list: 
1. I wish that when viewing 6 or more cycles on my iPhone, it would be formatted better with the start of each cycle on a new line. It’s formatted correctly when viewing 3 months but not when viewing more than 3 months. Makes hard to read and share. 
2. I wish that the number of days in each cycle would be indefinite, automatically numbered til the next cycle begins. Not a big deal. Just have to go back and edit the cycle once it’s over.

### 3/5 — Good but could be better

*2021-03-04*

The app is far more convenient than lugging around the printed chart or trying to remember everything at the end of the day. It is fairly simple to use, but I do have some suggestions for improvement:
Allow for longer cycles. For some that have irregular cycles, they can go for longer than 32 days. Either allow for a 35 day and 40 day, or try to get away from making people pick a cycle length at all. Consider instead a pop up box when someone enters an indicator that is considered a period day, asking them if they would like to start a new cycle. Or add it to the list of selections for each day.

**Developer response:** Thank you for your review! I would like to point out that the length of the cycle can be modified from the "Edit Cycles" tab by swiping to the left on the cycle you want to modify and clicking "Edit".  This functionality is depicted in the screenshots of the app on the app store. My wife mentioned something similar to me about your idea for starting a new cycle, and I will consider something like that in a future update.

### 5/5 — Love this app

*2021-02-26, version 2.1.5*

Very useful for charting! Easy to use!

### 4/5 — Share feature doesn’t work consistently

*2021-02-23*

This app is phenomenal! It makes it easy to chart each day. 
However, I tried to share via email with my NFP instructor and she didn’t get it. It did share via iMessage with my husband. This is a crucial feature hat should be fixed.
I understand the cycle length is arbitrary since you can override, but it would still be nice to be able to change it after initially setting up a new cycle. Plus, a cycle was longer than expected and I couldn’t add more days.
Overall, this is such a helpful app. Thank you for creating it!

**Developer response:** Thank you for your review! I have not experienced the issue you mention with emailing the chart when emailing with my wife.  As far as cycle length, the length of the cycle can be modified from the "Edit Cycles" tab by swiping to the left on the cycle you want to modify and clicking "Edit".  This is depicted in the screenshots of the app on the app store.
