The .json files also function as a shared database for both the patient and doctor app, so both patient and doctor can share messages as well as see the pills and missed drug events recorded by our synced 2-app system. The patient has a history list style for taken and missed drug events. The doctor will only see missed drug events but displayed on a calendar interface, since real doctors will have multiple patients and really only care about patients missing their drugs.

USER #1 (patient)

• The user started on the home page of the patient app. When asked to add a new pill, she was confused by and did not immediately understand that the rows on the home page were drug events. She saw "Manage Pills" but did not feel like it was something to go to to add a new pill. She thought maybe she was not on the home page so clicked on the top home button a few times (which did nothing since she was indeed on the home page..). She said she clicked on the home page hoping that the home page would give her a more high-level idea of how to use the app.** CATASTROPHIC: she did not know what page she was on. The app did not give her feedback at all.** MAJOR: "Manage Pills" did not convey what we wanted to convey. This naming issue has persisted since the first user prototypes where we tried "My Pills" and "Edit Pills" but always had some feedback with user confusion on what that encompasses.

• When trying to remove a pill from the manage pills page, she clicked on the pill's button only to realize that it was to edit that pill. When she returned to the manage pills page, then she discovered the "-" button next to that pill and deleted it correctly.**  MINOR: Maybe we should color the button (say bright red) so that the delete button is more intuitive and stand-out.

• User finally realized that the home page of the app contained drug events and that the app functions as a record for when she indicates (with selecting a drug event and pressing whether she "took" or "missed" the pill).** MAJOR/CATASTROPHIC: Our app layout for the home page does not seem intuitive. Perhaps we could have a clearer date and time indication, to emphasize a take-your-medications EVENT as opposed to what seems like a list of pills and some info displayed?

USER #2 (doctor)

• The user went to a patient's calendar page. When asked to delete a patient's pill, the user tried to click on the pill on the left column (the calendar then showed missed dates of that specific pill). Then the user tried clicking on the missed date purple bar that showed up in the calendar. The user finally sees the buttons at the top of the page, with "manage/edit patient's pills."
  • MINOR: Those top buttons might need to stand out more.

• When updating an existing pill, the user feedback that says "pill updated" was in color red, so user was at first alarmed thinking that she might have accidentally deleted it, because previously when deleting a pill, a red user feedback said "pill deleted."** MINOR: Color "pill updated" differently, not red. Maybe green? or blue?

• User would have liked the send button on the messages page to be able to work via pressing "enter."**  MINOR: Consistent functionality with other standard UI's.

• User was confused why when adding a new pill, the info did not show up in the calendar. User did not realize that the calendar only showed missed drug events.**  MAJOR: Our interface does not clearly or intuitively indicate the functionality we wanted to share with users.

• User would have liked to see some info of each drug on the calendar page.** (just a suggestion for additional features)

USER #3 (doctor)

• When the user was on the message page, she was asked to check the patient's pill history. She went to the page by clicking the "Patient" tab on the navigation bar. The user didn't realize that the patient's name in the message page is actually clickable and will lead to the patient's pill history page directly.
  • COSMETIC: The patient's name on the message page doesn't provide enough affordance to show that it is clickable.
