The study aimed to evaluate how effectively SubTracker assists users in managing their subscriptions, focusing on its usability, efficiency, and user satisfaction. We engaged 10 participants from key user groups, including young professionals, families, budget-conscious individuals, and freelancers/small business owners. Participants were asked to complete tasks such as adding new subscriptions, categorizing them, setting budgets, canceling subscriptions, and viewing renewal reminders. The goal was to identify any user pain points and gather valuable feedback to improve the overall experience.
