Screen	Description
Registration and Login	Registers the name, nickname, e-mail that identifies the user, and the respective password. After this procedure, the participant receives an account’s activation e-mail, and after activating it, he/she can login.
Panel	Figure 3a presents all performed actions on the platform where everyone can access their realized activities feedback and from their peers through notifications system or participants messages.
Checkin	Figure 3b makes available the necessary participants’ activities that must be carried out daily to prevent PI.
Sending and Receiving Messages	Figure 3c provides communication between peers through previously registered or personalized messages.
Sponsorship System	Based on self-help groups, such as alcoholics anonymous (AA), a godfather/godmother becomes a mentor for one or more godchildren. Thus, bringing this concept to the platform when registering, the system chooses the participant’s godson to him/her take care of and assumes the commitment to pay more attention to him/her.
Risk assessment	It evaluates the risk of acquiring PI based on 6 subscales: sensory perception, humidity, activity, mobility, nutrition, and friction and shear. The subscales from 1 to 5, respectively, vary between 1 and 4 points, and the last one varies between 1 and 3. The lowest resulting between 6 and 9 points from subscales sum is the highest risk indicating a VERY HIGH RISK and the least worrisome level between 19 and 23 points representing NO RISK. Moreover, for comparison and follow-up, the last 5 evaluations are stored.
Materials	Supports participants sharing prepared or indicated media by therapists who follow the wheelchair users’ reality selecting texts, audios, or videos to improve the life’s quality of these people through communication.
Challenges	Individual or collective goals that, when met, are rewarded with stars and points. They are users’ incentives to induce them to stay active in the platform.
Scoreboard	Dailies and general ranking display the score after each practice is done. The points’ registration per day aims to encourage new participants since everyone has their points reset at the beginning of the day no matter what actions preceded the current date. However, on the general scoreboard, all the practices carried out are counted since the participant joined the platform.
