User reviews

Women’s education

This was a great way to add on to what I already know as well as help tracking for when to repeat it and any notes you want to add for things you notice.

Great app

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!

Not for breast cancer survivors

The app offers recurrence rates based on outdated statistics and stages.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 β€” 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.

Knowledge is power

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!

Response from developer

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 β€œtest your breast IQ”.

Nice but stress provoking

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.
