Table 5 Changes made to the iKOALA intervention based on patient feedback

Think-aloud

When adding activities to ‘My activity plan’ several participants missed that there were 2 separate tabs for ‘Cardio’ and ‘Mind and body’ activities

We agreed to change the layout of this page so that all activities (including Cardio and Mind and body) we viewable on the same scrollable page but separated out into their respective sections rather than using tabs

Think-aloud

Many participants were unclear on how to access information about a particular activity by pressing on the image associated with the activity

We agreed to add a ‘More info’ button under the image to clarify how to access this information

Think-aloud

Several participants were unclear on how to ‘add a completed activity’ to their exercise plan

We agreed to add the text ‘Completed this week?’ text to the image to clearly identify where to add an activity

Think-aloud

Several participants could not determine how many activities had been completed in the ‘My activity plan’

We agreed to add a green tick when the task had been completed along with the number of times it had been performed (e.g., X1 for once and X2 for twice and so on

User trial

Several participants identified that steps and other activity data recorded through the Fitbit were not synced with the iKOALA app causing confusion

We agreed to make changes to the way the iKOALA app requested information from Fitbit to try to speed up the syncing process

User trial

Several participants were confused at ‘Opportunities in their local area” being displayed in text and on a map in the same page

We agreed to simplify this by just showing local opportunities on the map

User trial

Several participants felt that some activities were not relevant to them following the PA questionnaire

We agreed to review the suitability of the exercise to ensure they were relevant to individuals based on answers given in the PA questionnaire
