Suggestions for Improvements to the Functionality of the App
All the participants pointed out some flaws in the design of Plunde that could be improved. The functions related to deleting and saving, both notes, tasks, and reminders, in Plunde were the most challenging. Hence most suggestions for improvement concerned these functions.The delete function for messages was suggested to be changed from swiping to a “button/icon” to be tapped or double-tapped. A trashcan icon was suggested as an alternative as it was perceived as more in line with other apps familiar to the participants. Further, it was suggested that the save button for the personal notes feature should have been placed at the top of the page. What is more, to change the timing of reminders, a keyboard was suggested as a more user-friendly input method than the scroll function as in the current design of Plunde. Further, a snooze function for the reminders was requested by some of the participants.Other improvement suggestions were related to the wording or labelling of the features and functions in Plunde. Further, 1 participant suggested that the command labelled “change” in the personal notes feature would be more understandable if labelled “change text.” Another participant suggested renaming the feature “information” which relates to evidence-based knowledge and guidelines regarding lifestyle. The label “information” was perceived to wrongfully be understood as information about PlundeLastly, to aid in the navigation of Plunde, several of the participants suggested a help feature or alternatively a separate written manual. In this connection, 1 participant expressed that an app should be so intuitive that there would be no need for a help feature.
