Usability issues identified with the prototype of the Teaching Recovery Techniques app and the corresponding modifications.

Usability issues	Modifications to the app
Some of the video and audio recordings lacked the ability to rewind as well as the option for subtitles.	Rewind function and option for subtitles were added to all videos and recordings.
Users found the quality of some video and audio recordings to be low, affecting the overall user experience negatively.	The videos were rerecorded in a studio. The audios were rerecorded by the same narrator, while ensuring no interferences in the recording.
Users were bothered by difficulties related to the device, such as the screen going black during long audio and video recordings, and the lower tab bar being difficult to access with an iPhone.	Instructional text was added, directing the user to the device settings to enable the screen to stay on for an extended period. Adjustments were made so access to the tab bar is not affected by the type of device.
The Other People’s Stories exercise, aimed at identification and normalization, was generally perceived as important and helpful, but the audio recordings were also perceived as stressful to listen to. It could also be perceived as pressurizing to hear from others who have managed to overcome their difficulties.	A decision was made to keep Other People’s Stories in text format but exclude the audio recordings from the app. Additional information about the contents of the stories, as well as the purpose of the exercise, was added. A reference to other exercises in the app in case the user feels they would not benefit from reading other people’s stories was also added.
Users reacted to the advice to “reach out to someone close to you” and expressed that some people don’t have that option, which may be why they use the app.	A reference to the Other Support screen was added.
There was too little variety in the tips on sleep, activities, and positive self-talk.	More tips were added for each exercise.
The app only being available in Swedish.	The app was translated into more languages.
