Empathy is always key
Empathizing with the users does not end at the research stage, especially for a product aiming at potentially vulnerable users. A lot of times I need to push back on decisions that seems fun and useful but will complicate things for users and add to their cognitive burdens.
Testing it out with mentors
Mentors used to meet mentees at designated time, but with the App, they can potentially be reached at almost anytime. Will this make mentors feel like too much responsibility is put on them? Long-term usability studies like diary studies could be carried out to answer the question and help further iterate the design.
Providing self-help options for mentees
With the current iteration, the support that mentees get is exclusively from mentors (or mentors in training). To extend support to when the mentors are not readily available, design explorations on self-help features like anxiety relief exercises could be a potential next step.
