This feature was completed while I was the Lead UXUI Designer for ThyForLife . The goal was to make tracking daily measurements easier for users with thyroid conditions. 


Users need a way to track their daily measurements for their health and to report to their thyroid specialists. Users were noting their daily measurements on their Notes app, paper, calendars, etc., making it hard to locate crucial changes during their specialists visits.
Tracking”, and reorganising the app’s information architecture, so that other features requiring daily updates were also under “Tracking”. Symptoms, Superpowers (medication), bloodwork, appointments, and measurements (new). 90% of users used ThyForLife's existing daily tracking features: Symptoms and Superpowers.

Context &
During my 9 month contract at ThyForLife,  as their Lead UXUI designer, my area of focus was on the Wellness section of the app. This case study will focus mainly on the Tracking feature of the Wellness section.

ThyForLife is a thyroid management app helping users with thyroid conditions track their medication, symptoms, and overall health. The Tracking feature is part of ThyForLife's new premium section: The Wellness.

According to a survey conducted with 110 ThyForLife users, 85% of users have a separate folder for their bloodwork, and recorded additional measurements for their thyroid specialists. These included: weight, daily bowel movements, daily average temperature, and daily average heart rate. However, the app does not currently address these concerns.

The users’ current tracking method is inefficient

  1. Users need to set multiple reminders to enter their data 

  2. Human errors in data entry 

  3. Lost entries and bloodwork

For the first few iterations, we prioritised accurate and efficient tracking. Users need to be reminded to track daily and be able to view their daily measurements all in one place. Based on our user interviews and medical advisors on the ThyForLife board, tracking the user’s weight, bowel movement, daily average temperature, and daily average heart rate were the most crucial for thyroid patients.

Notifications to ensure users got reminders to track.
Current users were already accustomed to the reminders section for the app for their Superpowers, Symptoms, and Doctor’s Appointment reminders.

So, adding the tracking reminders in the same place would make sense for the user’s experience. While over 89% of users were able to locate and use the new Tracking reminders, more testing should be conducted to determine the generalisability. 

In addition to the updated reminders page, I wanted to make sure users got updated push notifications for each (as they do now with their phone's reminders). 

So, I illustrated and designed new icons. 
With accurately tracking bowel movement, thyroid specialists on the ThyForLife advisory board explained that bowel movements may be separated from Type 1 - 6. However, this was not clear to for the users so we A/B tested designs:

Since some users had wearables that provided measurements like daily average temperature and daily average heart rate, I anticipated challenges with both daily average heart rate and temperature measurements. 
However, 40% of users measured their heart rates manually. For example, User 1 measures in the morning post-medication, mid-day, post-exercise, and before bed.
Users may be forgetting to record because they have to switch between multiple apps to record.
As such, I created the option to track the user's heart rate and included an option for tags.

After another round of usability tests, users were able to use our prototype with ease. We had a 84% usability rate. 
However, viewing historical data was also crucial for users, so I made a few changes to the landing screens.

How does this feature integrate into our current product?
Previously, ThyForLife only tracked the users Superpowers (medication), symptoms, and bloodwork. Now, with the new Tracking feature, users can track all other daily measurements within ThyForlife.
Next Steps
Syncing wearables = less human error 
While 40% of users did measure manually, we should explore options to sync wearable data so that it decreases human error.

To the left is a quick mock up for what Tracking could look like with wearable data syncing.
