User Reviews

Users praise the app for its attractive, at-a-glance month view and color-coded, easy-to-use interface, often preferring it to the built-in iPhone Calendar. However, repeated issues curb satisfaction: data loss where events/reminders disappear or calendars blank after updates, intrusive Temu ads with explicit imagery, and reminders not triggering reliably. Loading/sync problems further reduce reliability. Overall, strong visuals and usability are offset by significant reliability and ad-related drawbacks.

Pros

Clear, at-a-glance month view with readable event labels.
Visually appealing UI with color coding and customization.
Easy-to-use and preferred over the iPhone Calendar by several users.
Helps you see your schedule at a glance with color-coded entries.

Cons

Data loss: events and reminders disappear or calendars go blank, including after iOS updates.
Intrusive ads, especially Temu, including explicit imagery, that disrupt usage.
Reminders/alerts do not fire reliably or as set.
Loading/sync reliability issues; events fail to load or save consistently.
