### 5/5 — Great app

*2026-07-03*

Really helps me remember to do my exams every month, plus helped me learn a lot more about how to do them and what I should be watching for. I've recommended this app to my friends!

### 1/5 — Not for breast cancer survivors

*2026-04-04, version 7.0.0*

The app offers recurrence rates based on outdated statistics and stages. It is deeply dangerous to tell a breast cancer survivor that she/he has a 30% chance of recurrence without first asking for details about subtype of cancer and stage, and also specifying what type of recurrence. Most breast cancer survivors don’t have a 30% chance of recurring — and yet this is the information this app peddled in its very simplistic quiz.

Fear of recurrence drives depression after treatment for many breast cancer survivors. If you’re going to estimate someone’s recurrence risk, you should do it carefully, cautiously, and with a great deal of consideration as to the mental health issues that face the survivor cohort.

I unfortunately got no benefit from this app. As a breast cancer survivor, it taught me nothing I didn’t already know. And it frustrated me with its simplicity.

### 5/5 — Knowledge is power

*2026-02-14*

The videos and graphics are so incredibly helpful. I’m so grateful to know how and when to do a self exam, as well as what I’m supposed to feel and look out for. The monthly notifications you can opt into that remind you to do a self exam just might save your life!

**Developer response:** Thank you so much for your kind review! Now that you have the app, you can test your breast health IQ with our latest breast health quiz! Just go to our website below the 12 signs of breast cancer and click “test your breast IQ”.

### 3/5 — Nice but stress provoking

*2025-12-20, version 6.2*

I like this app a lot. It provides a lot of good information. My only issue is the reminder notification is never right. It always pops up 5 to 10 days early. I can’t figure out how to fix it. It’s unnecessary stress.

### 5/5 — The only breast exam app you need!

*2025-12-09, version 6.2*

This app is so easy to navigate! From the fun and colourful design to the easy to follow self-exam guides - it makes staying on top of your monthly breast-exams a no-brainer. It also comes with a period tracker, explains clearly what possible breast cancer symptoms to look for in and on your breasts, and reminds you to check yourself every month at the right time. On top of it all - it’s free and doesn’t collect your data!!! Couldn’t ask for more!! 🥳

### 2/5 — Data disappeared

*2025-11-09, version 6.1.9*

This app would be great, except after setting up my profile, entering all my date, including my company code, tracking my cycle, and completing an exam, I returned the following month for another self exam and it was all gone. I had to start from the beginning.

### 4/5 — Risk assessment not working properly

*2025-10-20, version 6.1.8*

I tried to use the risk assessment quiz & it keeps restarting in the middle of the quiz. Hopefully this kink can be worked out, otherwise love the app!

### 5/5 — Best app for breast health information

*2025-09-26*

Hands down best app for breast health information.
Great tutorial for how to do a self breast exam. How often to get a mammogram and a schedule a mammogram option that leads to an interactive of map of places near you that provide mammogram services!

### 3/5 — Great info. App seems buggy.

*2024-09-26, version 4.9.0*

I’m tech savvy, but there are a lot of non-intuitive icons in this app (“mystery meat”). Also, the main screen’s content is all overlapping for me (on an iPhone 8). The Mona Lisa video said to go to knowyourlemons.COM, but the text in the video listed the .ORG. (Hoping the organization owns both TLDs). All in all, I’m hoping there will be more updates to clean things up, so I’ll keep the app on my device for now because getting reminders for a self exam would be good. There are just some odd quality control things going on…

### 2/5 — Great but stopped working ended up deleting due to lack of support to resolve my issue.

*2024-04-27, version 4.6.0*

Never received a notification when it was time to do a breast check. 

Then all of a sudden I couldn’t login. The pop up screen to enter my passcode didn’t appear. I contacted them via the help/support feature on the app but no one responded.
 
I then contacted them via instagram eventually I got a reply telling me to delete the app and reinstall it. That only worked for one login when I tried again I experienced the same issue. Contacted them again via instagram and got asked the usual questions, ensure that I’m using the latest version which I was. Told to delete the app which I explained I had. Then then sent me a link on how to delete the app (I’m a millennial). 

I just deleted the app after months of little to no support. Just unfollowed them on instagram. I love the idea of the app but if it doesn’t work then there is no point. 

On a hunt for replacement app.
