“Overall, I feel this application has a lot of potential. Most of my feedback centers around privacy, security, and user trust, as I believe these will be the key factors in determining whether users feel comfortable adopting the application long-term. Before investing their time and trust, users generally want to feel confident that it's secure — once that trust is established, convenience becomes even more valuable, and I truly believe this is something you can achieve.”
