Focus area and potential solutions to improve intervention based on findings

Focus	Potential solution and refinement strategies
Test strip	Develop additional resources on completing test (e.g., video instruction, visual diagram outlining steps, list of ‘tips’ to take high-quality pictures) Request urine tests on random days once per week rather than more frequent submissions
Unclear report submission	Provide clear feedback that report was submitted/completed (e.g. “Today’s report has been submitted”) Reduce photo loading and upload times
Participant facing features	Add alarms and alerts (e.g., medication, appointment reminders) Add a treatment timeline or milestone indicators (e.g., treatment duration, what to expect such as medication changes at month two of treatment) Make the notes section more specific (e.g., things to remember, medication names, appointments, etc.) One participant used a separate notes app to keep track of these things.
Treatment supporter facing features	Add an announcement function that the treatment supporter could use to alert all patients (e.g. being gone for a few days) Increase technical support
Forum not heavily utilized	Change forum layout more familiar style (e.g., WhatsApp-style chats) to increase participation/ease of use Initiate use at the start of treatment
Maintain and improve useful app features	Access to a treatment supporter Side-effect reporting Calendar view/visualization of treatment tracking Treatment progress indicator/graphic (e.g., days in treatment, remaining)
