Instead of trying to track all my symptoms, lifestyle management technics, period, etc in a journal or Notes app, I have my info organized in one easy location. I also like that my data will help researchers learn more about the disease. ### 5/5 — Thorough and research-oriented *2024-08-02* I’ve been trying to understand my symptoms and what I can do about them and this app has been a major help. Extremely specific and focused. I’ve had a lot of other symptom/period tracking apps, but this one is both more thorough and and clearly dedicated to a research mission that I’m able to participate in simply by tracking. Knowing my data is totally private is also a bonus. ### 2/5 — Won’t load *2024-07-19* The app is actually good and worked for a couple of days. Now when I try to track my day or a moment, it just spins and won’t load. So I have not been able to track for several days. Update: worked again for a couple days. Now when I go into anything (ie track this moment and click on pain) it’s just blank. Nothing in the screen where the buttons normally are. Have deleted and redownloaded many times now. My connection is good. ### 2/5 — Won’t load *2024-07-05* The app is actually good and worked for a couple of days. Now when I try to track my day or a moment, it just spins and won’t load. So I have not been able to track for several days. ### 5/5 — Finally! *2019-12-16* I’ve tried multiple endo/symptom tracking apps and they all fell short of my expectations. I’ve only had this app two days and it’s already so much more useful and intuitive than any other app I’ve tried for tracking my endo symptoms. It’s so encouraging to know that there is actually research being done based on info from this app too. I rarely go to the doctor and I’m terrible at conveying the severity of my symptoms when I do go, I think this will be an incredibly helpful tool. ### 5/5 — Love it *2019-08-08, version 1.4* Love the app handy to track things ### 4/5 — Needs a little work *2019-03-06* I love that this app asks the questions that I don’t seem to be asked by anyone, with symptoms that have not been communicated to me as being related to endo. I love that I have the ability to track my day in general and options to track specific moments. With that being said, half of the time the app does not log my entries and does not count anything toward my tracking history. I would love to see a trend section to compile all of the symptoms experienced so I can communicate these experiences with my doctor. Other than that, it’s a very good app. ## Frequently asked questions about Phendo ### What is Phendo?
