### 4/5 — Love the Integration

*2025-10-09*

I love that I can integrate my TempDrop, Proove, and Kegg! I hope in the coming months to learn the newest version of the Marquette method of NFP that uses the Mira and use that because it also syncs with the app! I started using the app because I have been a participant through a study on the Kegg device. I hope to continue using this app after the study ends purely for the integration features. My favorite charting app, is ReadYourBody, I just wish they had more integration like this app. 4 stars because sometimes there’s glitches and wish that it was a nicer layout/user experience.

**Developer response:** Please email us your layout/UX ideas to help@chartneo.com and we will seriously consider them!

### 4/5 — Clear and easy to use

*2025-03-08*

I’ve been chatting with Cerebro Model for 10+ years. This is the best way ever! So easy to use and view

### 4/5 — Good fertility charting app

*2024-02-20, version 1.34.13*

Relatively easy to use, although I would recommend you have an instructor help you, at least to begin with. Remember, the app is only as useful as the data you put into it, so make sure you are recording all of your observations. Would be helpful to have a section on the app somewhere that explains the colours/notations and some of the extra features. Thank you for developing this app to accompany the NeoFertility method!

### 5/5 — Uncover what is not right about your cycle

*2023-11-19, version 1.34.11*

With the help of my fertility specialist, and this app, I am able to clearly see the patterns that are not right in my cycle. I am now able to take this chart to my gynaecologist and get the help I need to change these issues I’ve been experiencing.

### 5/5 — What I’ve been looking for

*2023-02-19*

I’ve been charting my cycle for family planning for a decade, and have *finally* found the app that has it all.  I can track my cervical fluid with ease, while also adding in any cross checks I might want to each cycle, and can see it all in one place. You can “scale up” or “scale down” depending on what data you want to track, it’s very user-friendly, and knowing that it follows European guidelines for privacy (which are more rigorous than HIPAA), I have zero worries about my private health information going anywhere except my healthcare provider. Great value for the price!

### 4/5 — Overall great app, needs minor tweaks

*2023-01-10*

You should add lower back pain as a symptom to track.

Can you make the “log symptoms” and “view chart” buttons on the main screen a different color? Usually when a button is grey it signifies that there’s some sort of error and you aren’t able to click it. They’re also hard to read.

**Developer response:** Great ideas! I'll make those buttons a little darker by default. I just need to think up a good icon for lower back pain. :) Stay tuned!

### 5/5 — Love this app!

*2022-12-05, version 1.34.2*

Best app to combine all options of FAMs.
So user friendly

### 5/5 — Best cycle tracking app!

*2022-09-11*

Chart Neo is exactly what I needed as I started fertility awareness. I love that it syncs with my Tempdrop. It makes it so easy to record cervical mucus, temp, tests, notes, etc. The chart view is really helpful in identifying patterns around my fertile window, and the calendar view is useful too. It’s more than the typical predictor-type apps because it relies on the data you input to determine where you are in your cycle. Overall, I couldn’t be happier with it!

### 5/5 — It’s perfect!

*2022-08-25, version 1.34.1*

Great app for anyone wanting to track their cycles.

### 5/5 — The best out there- including privacy!!

*2022-07-28*

Love this app, and the privacy it provides really helped make my decision to use it. Privacy and accuracy are very important with this kind of app. This app applies to many different npf choices with ability to have input of different types (creighton - cm cks, sympto-thermal cks) so if you prefer to chart a particular way out of old habits or are learning more this app is the one for you. The newest version provides a more modern look, with all the same abilities as before. It’s nice to get a birds eye view of the current cycle. The colors still correspond nicely to cycle days (no silly flowers or faces, thank you). My only request- is to bring back the ability to easily swipe to the previous days and swipe forward again. Right now, you see where you are from a total phase perspective , and have to go into log symptoms and then move back and forth between days. It feels a little awkward. Maybe being able to tap on the cycle would then take you to current day and then swipe? Idk, just a request. Not a deal breaker for me. The app is too good to walk away from bc of a simpler preference.

**Developer response:** Please reach out to me at help@chartneo.com so I can better understand what feature you want back -- in the new design, you can move your finger in the top bar to switch between days instead of swiping. You can also tap on a day in the bar to go directly to it.

### 5/5 — Easy to use!

*2022-03-24*

Really appreciate this app!! Very clear, fully functional, and easy to use!!

### 5/5 — Must have for tracking

*2022-01-08*

Where was this app all my life. This made tracking so easy and I wish I had this in middle school. Would have been able to identify symptom trends a lot faster.

### 5/5 — So easy to use

*2021-10-01*

This app makes it so easy to chart especially if you are new to it. It also syncs with Tempdrop automatically so it makes it even easier. I love that I can compare multiple cycles at once. You can zoom in or out to see as many as you want because it stacks your cycles. I would definitely recommend.

### 5/5 — Fastest app I’ve tried

*2021-09-22*

Great app, loads quickly, has all the features I’d need. Only thing I’d change would be to have the ability to change the cycle start date in case you tapped the wrong button! But as I don’t mess that up often, it’s not too much of an issue.

Update—Thanks for the reply! I see, yes it does change the cycle start date when I uncheck that button! :) Now everything works great!!

**Developer response:** Speed was super important to us -- nobody wants to wait for an app to load when charting. You *can* change your cycle start date, though! Look for it under the Bleeding tile.

### 4/5 — Chart Neo App

*2021-07-25, version 1.32.23*

Veľmi užitočná aplikácia pre ženy, ktoré si potrebujú zapisovať komplexne informácie svojho zdravotného stavu a fungovania počas cyklu či už sú v tom začiatočníčky alebo expertka... pripomienky, prehľadnosť, priestor na poznámky a pocity aj možnosť zdieľať info sú veľmi praktické. Odporucam.

### 5/5 — Love Automatic Syncs

*2021-06-27, version 1.32.23*

Automatically syncs to my Tempdrop and easy to read charts.

## Most critical reviews (10 lowest-rated)

### 1/5 — Waste of money

*2025-09-24, version 1.34.25*

There is much work needed to be done on this app. The information is not forthcoming. They gatekeep a lot of the info behind “consultants” who you have to pay extra to work with. In fact after you meet and pay for a “consultant” you somehow realize the app they sign you up for (this one) has a yearly membership. 

There is no liberation here, I assure you. I feel stupid for paying money for this and for the consultant.

Big thumbs down.

### 1/5 — Doesn’t say the price

*2020-05-30, version 1.32.4*

I read the reviews and they are correct , it really does not say the price at all, it makes you sign up first and says a free trail for 45days.

### 1/5 — Nowhere says the cost of app

*2020-05-27, version 1.32.4*

how much does it cost after the trial? it doesn’t say ANYWHERE. in response to response: NOT TRUE, it doesn’t say the price in the app store. 

for those in the USA, after logging in to the app and setting it up i was able to click on “purchase” in the menu and it says a year subscription is $9.99. i wish this price was easier to find and possible to find before downloading and signing up.

### 1/5 — Only benefit is liking to Tempdrop for iPhone user

*2020-05-14, version 1.32.4*

Very poor analysis system. UX/UI is not great either. Most fertility check apps are way better.

### 1/5 — Price

*2020-03-29, version 1.32.0*

What is the price after the 45 day free trial? And is the price for life or do you have to continue to make payments?

### 1/5 — No go

*2019-05-02, version 1.24.0*

Can’t even set up an account because the keyboard stays up after email/password entry, preventing me from reading/answering the end of the “is your email address correct” question.

### 1/5 — Pretty useless

*2019-05-01, version 1.24.0*

The app crashes every time when entering data. This renders it useless.

### 3/5 — Log n & integration

*2022-11-01*

It’s a great app until you have to log in all over again and reintegrate with Tempdrop.  I’m so tired of constantly changing my passwords on both.  And having to go to websites to log in and do the integration is dumb.  Most apps can open another app to do the link.   I will not be renewing my subscription.  I’ll stick with RYB.   It’s so much better.

**Developer response:** Thank you for letting us know - we are unfortunately limited by the options that Tempdrop gives us and can’t do anything about the Tempdrop login, as that is their website. In any case, I revisited the integration and was able to remove the extra Chart Neo app login, which should streamline things and make it easier. Best of luck to you in your cycle tracking journey!

### 3/5 — Can be improved

*2021-08-18*

- The are where you have to swipe left to right to log symptom level will confuse the app that it is asking to go to the day before. Every time I swipe to log symptom I will have to go back and forth many times. It’s really bothersome. Please fix this.

**Developer response:** Does the app redesign make this easier now? I’d love to know what you think!

### 4/5 — Intutivne

*2025-10-14, version 1.34.25*

Veľmi intuitívne používanie, otázniky sú po ruke na vysvetlenie. Veľmi nápomocné, ľahko sa zapisuje

### 5/5 — Love this! Easy and stress free

*2025-05-27*

I’ve used other apps to help chart fertility, cycle, etc. This one is better than all of the others. It really takes the guess out and analyzes the data for me. It asks all the right questions and allows me to chart everything with notes. It even reminds me of important things I need to do. I love that it syncs to any device including my husband’s, giving it a real “we’re in this together” and I don’t feel like I’m doing it all by myself. After all, it takes both of us to make our baby. (One minor detail for improvement in the Symptoms: in addition to increased appetite could they add decreased appetite, which is usually the one that happens to me during my cycle.)

### 5/5 — Spokojnosť

*2025-03-08, version 1.34.21*

Vyskúšala som už viaceré aplikácie aj s teplotou, s touto som zatiaľ najviac spokojná a odporúčam aj svojim kamarátkam. Vyhovuje mi, že je kompatibilná s tempdropom, ale je oveľa lepšia ako ich aplikácia. Ak váhate, či to stojí za tie peniaze, určite áno, odporúčam..

### 5/5 — Very Intuitive!

*2025-01-30*

Love that charting is so easy and I can track multiple different biomarker signs to identify what’s going on. Best feature is that I can share it directly with healthcare professionals to collaborate on diagnosis and treatment course.

### 5/5 — Great app for fertility and women’s health awareness

*2025-01-20*

I’ve been using fertility awareness based methods of fertility planning and health monitoring for over 10 years and this is my favorite app to use. I love that it integrates with Tempdrop. Customer service and tech support is excellent.  The app is also very easy to use and looks great!!!

Thanks for creating an app that integrates into my life so easily and integrates with the growing field of femtech products on the market.

### 5/5 — Best all inclusive tracker out there

*2024-12-31*

Like the title says, this app truly is the best app out there for charting your fertility. It tracks symptoms, medications, bbt, mucous, other fertility test results and more. 10/10 recommend. It keeps me organized and is easy to share with my doctor. It’s very much worth the cost.

### 5/5 — Great!

*2024-10-15, version 1.34.17*

Love it!

### 5/5 — Great fertility app!

*2024-04-02*

Great fertility app, especially for anyone with medical issues or undergoing fertility work up!

### 5/5 — Super app

*2024-03-07, version 1.34.13*

Skvelá app na zaznamenávanie a sledovanie cyklu👍🏼 plus šikovná pomôcka v spolupráci s doktorom

### 5/5 — Good for tracking body symptoms

*2024-01-27, version 1.34.13*

Good for tracking body symptoms
