## Review summary

Reviewers largely praise Check Calendar for its simple, easy-to-use design and its effectiveness in marking days and tracking habits, with visible progress and emoji customization. It’s well-suited for simple schedules and motivating check-ins. However, several users warn about post-trial paywalls and features locked behind payment, sometimes calling the pricing too high. A few report reliability issues with tick marks not reflecting correctly, and there are requests for enhancements such as viewing all tabs at once or allowing multiple checks per day. Overall, a lightweight tool with solid core functionality but monetization and missing advanced features.
