Hopefully this kink can be worked out, otherwise love the app! ### 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… ### 4/5 — Great app but needs tweaks *2023-04-30, version 3.9.0* Great app and fulfils an important function. But it would be helpful to be able to adjust the timings if your cycle length varies and it would also be better if the self-check reminder stayed on your Lock Screen/showed as a wee red circle on the top right corner (whatever that’s called!) of the app icon. The reminder generally pops up at 9am, which I don’t imagine is a convenient time for many to do a self-check! ### 5/5 — This app saved my life *2022-05-04* I’m 40 and no one in my family has ever had breast cancer. A year ago I noticed an odd-looking patch of skin, and didn’t really think anything of it at first. A few weeks later, it hadn’t gone away, and I started to get that sinking suspicion… I googled, found KYL, and learned the 11 non-lump symptoms — I’d had no idea previously that there were other symptoms! *Because of this app* I made a doctors appointment to get checked — but, when I went in my physician did an exam and said that because he didn’t feel a lump, I was fine, and not to worry. SOLELY because I knew about my breast health because of KYL did I push back and demand a mammogram. A week later I was diagnosed with stage 3 breast cancer. My oncologist says the chances of a recurrence are very low because I caught it early. Cancer is awful to go through, but if you have to go through it your chances of successful treatment are much improved with early detection. The Know Your Lemons Foundation is a gift to all women. **Developer response:** Hello! We are so touched that this app helped you! We'd love to hear how you are doing and learn more about your story. Please reach out to hello@knowyourlemons.org, we'd love to connect! xoxo ### 5/5 — Bright, Beautiful, Informative *2022-01-03* This app is loaded with information, all presented in bright, beautiful graphics. It doesn’t just keep track of things or send you reminders—it also explains the WHY behind everything, using a friendly, conversational approach (and, of course, lemons 🍋). The whole concept is brilliant and life-changing! **Developer response:** Thank you paginacurrien for the review! We’re happy to hear how much it has helped you. ### 5/5 — Easy To Use and Super Informative *2021-11-18* The risk assessment had me become more aware of family medical history to better support my answers. **Developer response:** Thank you DaniLu18 for the review! So glad this helped you know your normal better by looking into your family history. ### 5/5 — Breast Cancer Education App *2021-10-15, version 3.2.2* Informational, helpful, and beautifully designed. I’m sharing this with my mom and sisters! ### 5/5 — User friendly and informative! *2021-10-05* Very easy to use and I’m so glad to know what to be looking for and how to properly do self exams. The design is so thoughtful and well done which I appreciate so much! **Developer response:** Thank you for the review jbtipps! Glad the app was able to help you so much! ### 5/5 — Great info that you don’t often get in a Drs. Office! *2021-10-04* This app is beautiful, simple and so easy to use. It’s very self explanatory for a non-techy person such as myself. It provides such great and helpful information that doctors just don’t tell you! It’s going to save so many lives! **Developer response:** Thank you for the review burtlindsay! Glad we were able to provide this educational information for you all in one place! ### 5/5 — Unique and Simple *2021-10-04* This is a great way for early education and proper timing of events when trying to prevent significant concerns for potential cancer situations. Medical advice is always recommended but this is a fun and easy way to learn more about it without doing all the research. Very ingenious, I love it. **Developer response:** Thank you Wesley for the review! Thank you for pointing out that all the information we provide is backed up by reputable sources, and that we always recommend talking with your doctor. ### 5/5 — So Helpful *2021-10-02, version 3.2.1* Easy to use and has taught me a lot. Love the option for reminders. ## Most critical reviews (10 lowest-rated) ### 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. ### 1/5 — I really wanted to love it, but not all cancerous lumps are hard! *2023-12-08, version 4.3.4* Hi, I really wanted to love this app and recommend it to all my friends. I downloaded it and watched the ‘How to self-exam’ video and was really disappointed to hear that they split lumps into 3 groups: hard lumps like lemon seeds, soft lumps like peas and soft lump like beans. The video then classifies hard lumps as cancerous and soft lumps as either lymph nodes or milk lobes. This is really dangerous! Not all cancerous lumps are hard. My cancer was lobular breast cancer, which often doesn’t present as a lump. Mine did present as a lump but is was soft and squishy - more like a blister. I agree that not all lumps are cancer, but if I’d watched this video, I might not have checked it out. Please correct and update your video as I’d love to give you 5 stars! 😊 ### 1/5 — Can’t enter *2023-08-16, version 4.1.0* Can’t get in the app once I hit Enter Rock Star?? ### 1/5 — Doesn’t work *2022-01-05, version 3.4.0* Reminders don’t work and are inconsistent. ### 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. ### 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. ### 2/5 — Wanted it to work *2023-09-22* Just downloaded this app and was ready to utilize it. Unfortunately I couldn’t get past the age portion of the screening quiz as it had no options but my haptic feedback was going off like it was an option to scroll for your birth year. The only numbers it would show were 39 and 40. As I am 29 this obviously now the Ed of these options would reflect my age to accurately relay my risks. Really bummed. Super cute graphics though. **Developer response:** Hello! We found the bug and got this fixed. Just redownload and it should work perfectly. :) ### 2/5 — Cannot re-enter! *2023-08-07, version 4.1.0* Great app. Good information and features. But….once I have entered the app once I cannot renter. I see the button called “enter rockstar” when I reopen the app but it does nothing. Tried reinstalling the app. Same thing. Not much good if I can’t re enter and use some of the tools. ### 2/5 — No reminders *2020-08-24, version 2.0* This app isn’t keeping up with my cycle and doesn’t send reminders for the self-exam. It has valuable information when you go into the app, but I wanted the monthly reminders. ### 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. ## Most praised reviews (10 highest-rated) ### 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! ### 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”. ### 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!! 🥳 ### 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! ### 5/5 — Incredibly Knowledgeable *2024-03-02, version 4.4.0* This app changed the way I view myself exams. I have sent it so to so many friends! ### 5/5 — I know my lemons! *2023-04-19* I really enjoy this app. I like that it has the option for no menstrual cycle. I’ve always been paranoid about breast cancer as my great grandma had a prosthetic breast when I was a kid. They tell me she’s a “distant” relative and it’s not of concern but that’s not how my brain works. Now, my friend I’ve had since 2nd grade has recently been diagnosed with breast cancer. Thanks for making an easy tool! **Developer response:** Thank you for sharing your story and for the 5 ⭐️ review 😍. We would love to hear more of your story!

Save a life! Save a breast! JUST DO IT! Get the APP and follow the prompts…Better health will follow! 😉❤️ ### 5/5 — Love This App! *2022-12-30, version 3.8.3* This is such an amazing App! - Especially for me, because I am considered High Risk for Breast Cancer. Thank you for helping to save lives! ### 5/5 — Everyone needs this app! *2022-11-17* I was just diagnosed with breast cancer and I’m too young for a mammogram! So I began looking for an app to recommend to family and friends! They have apps for everything so why not breast exams. I love this app and wish I knew about it earlier which may have helped my situation… However, I tell all of my friends and family to use it so hopefully if they get cancer it is caught early. Highly recommend for every woman no matter the age because cancer doesn’t care how old you are and it’s happening to younger women!!! **Developer response:** Thank you so much for your review and for sharing our app with your loved ones! Women have told us they were able to find their breast cancer early thanks to our app. Keep sharing!

Got the all clear now having had chemo, surgery and radiotherapy. I wouldn’t have felt confident about what I was feeling for if it wasn’t for this app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
