Medical & Health Tracking Apps

Data is everything in my world.  As an engineer, I could track anything with enough data.  It should come as no surprise that I'm fascinated by finding ways to track my Sjogrens symptoms and other health data.  This will be a living document, because as I try new apps and devices I'll add to it.  Note that I'm only including medical tracking apps and not food logging, weight loss, or fitness apps. There are too many of these to count and everyone has their own preference. Also, I only use Android products. Sorry, Apple users!

Apps (Items in BOLD are currently in use)

• Symptom & Medication Tracking

• WebMD Allergy
• I used this for a little while to try to help me determine when I was probably going to have a flare-up based on the allergen in the air.  As far as environmental allergies go I'm pretty much only allergic to dust, which I could get exposed to even on a day when the dust was low according to this app.  I could see it being useful to people who have allergies like ragweed or tree pollen.  I don't recommend using this app as a way to figure out what you're allergic to.  A simple prick test is way more effective and not too expensive (granted, I have decent insurance in a country where that's not a given).  
• Clue Period Tracker
• Before I had my Nexplanon implanted I used Clue for its intended purpose.  I also used it to remind myself to take my daily pills (not just birth control).  I tried to use it for symptom tracking - in fact it had symptom tracking in place for things like headaches as well as the ability to add custom items - but ultimately I didn't like the way the symptom tracking was displayed and I found it a bit clunky to use. I understand that they've had a few updates since I last used it, but I'm not interested in returning to that app. 
• Med Helper Pro
• I used Med Helper Pro for about a year after I was first diagnosed. Not only did it help me keep track and remind me about my medications, but it also had a section to keep track of my doctor's info and my pharmacy info, which you know is pretty nifty if you've had to fill out half a dozen doctor's office forms. It had some primitive vitals monitoring, but I was unhappy with how the data was taken displayed and the app felt very limited in that capacity.  
• My Vitals
• I used My Vitals for several months (at least 6) and for a little while I was happy with its features.  It had most of the features I was looking for: medication reminders, vitals tracking, and even a medical reports section.  It did have some analytics for vitals tracking, but the things that could be tracked weren't as flexible as I'd like and I wasn't super fond of how it exported the data.  
• CareZone 
• I'm currently using this app.  There are two things I like most about this app. First, I like that I can input my medications by taking a picture of the bottle or box if I don't want to enter it manually.  This saved me so much time when I first started using the app.  Second, there are way more symptom/vitals trackers available in this app than any other I've tried.  I can track Body Temperature, Sleep, Weight, Headaches, Pain, and Nausea, which are options that I've rarely seen individually in other apps much less all in one app.  There are a lot of other options such as A1C, Blood Glucose, and HIV counts that I don't need, but I like that they are available.  And the way the data is displayed, with options to view different intervals, which is handy depending on the context of the symptom you're tracking.  It also has options to add contacts (like my doctors), pharmacy information, insurance information, and random photos and files I find necessary.

Obviously this works better when you populate the data.
