What people say
Rated 4.7 out of 5 from 40+ ratings on the App Store.
- My health, “This has given me a great tool to discuss my health issues with my doctor” (WVa Smitty, United States)
- Super!, “Very clean and well organized, nicely customizable. Practical widgets for the home screen. Exactly what I was looking for, thanks 👍” (jxleya, Germany)
- The app I was looking for, “I highly recommend this app, no annoying ads etc, straight to the point of keeping a track of health symptoms, the best health monitor app I have ever used.” (Trisroy-Best, United Kingdom)
- Very useful and private, “The app is simple, fun, and life-changing for me. I chose it mainly so that my data is never shared, and because it’s the easiest to use. I used to write my symptoms down in a notebook; now I do it every day on the app to track how they change. Being able to also log my everyday activities to see their influence is very handy. I recommend it!” (Solex94, France)
- Exactly what I was looking for, “Out of all the symptom tracker apps, I found this to be the easiest and most straightforward. It “writes” to the health app, which is exactly what I wanted. All the others only “read” parts of the health app data, and didn’t truly write any data back. This helps me visualize my chronic symptoms soooo well.” (EB1700, United States)
- Simple and useful, “I’m not really into tracking mood and habits but this app has shown me the benefit of doing so and has helped me reflect on my day to help find the positives and see where I can improve.” (GavinLanoe, United Kingdom)
- Very useful, “This app is wonderful. You can add symptoms and rearrange them as you like. The best part: your sensitive health data is only stored on your own device.” (WhoKnowsTypo, Netherlands)
- Great app, “Finally a simple iOS 26 symptom reporting app, thank you 😀” (stranack, United Kingdom)
- Top-notch, “Finally an app in which I can collect and analyse all my symptoms. And that reminds me to log them.” (sunsoul01, Austria)
