Many smartphone users in their 50s use 3-5 reward apps simultaneously (Cashwalk, Toss, Naver, etc.), but their actual earnings from each app are scattered and impossible to track. They spend 30-60 minutes daily on quizzes, step counts, and check-ins without knowing whether their monthly take-home is $2.25 or $22.50. In particular, they often fail to recognize hidden losses such as point-to-cash conversion rates, tax deductions, and expiration dates, leading to activities that pay below minimum wage per hour.
Solution
When you input the list of reward apps you use and your estimated monthly activity time, it automatically calculates estimated total monthly earnings, hourly return rate, and expected loss from point expiration based on an average earnings database per app, and provides a report. Key features: (1) earnings simulation based on average earnings DB of 20 reward apps, (2) ranking by efficiency relative to time investment, (3) alerts for hidden losses from point expiration and conversion rates. Differentiation: the first service to view 'all reward activities' as a portfolio rather than individual apps.
Target: People in their 50s-60s, using 3+ smartphone reward apps, with ample time after retirement or at home, interested in small side income.
