### 2/5 — Time zones

*2025-07-15*

There are only a few time zones to choose from and mine is missing, so it’s useless to me… otherwise I think it might be a neat app

**Developer response:** Hi there! Sorry your frustrated with the Timezone, but there should be enough covering most if not all. What time zone are you in and I can make sure I have it integrated! 👍

### 5/5 — Nice!!!

*2025-05-06, version 1.11*

This is great. Nit: Would be great if it also showed the selected calendar’s event with a toggle or something!

### 5/5 — Must-have for Scheduling

*2024-12-09, version 1.11*

I stumbled upon this app by accident on Reddit, and it turned out to be exactly what I needed. 

It’s perfect for managing and coordinating my personal and work calendars whenever I need to find an open time for a meeting or appointment. It syncs seamlessly with my iCloud and Outlook calendars, making it super convenient. 

The developer is also incredibly attentive to feedback and quick to implement new features or resolve any issues. 

Overall, I’m really happy with this app - it’s been a fantastic help so far!
