Great for time blindness

Exactly what I needed!

With ADHD it can be really difficult to conceptulize time, and even if my next task/event is 2-3hrs away... the stress feels like I'm already late.

Being able to glance at my watch and see how much time I have left until my next scheduled event is a gigantic relief, and helps me to accomplish so much more during the day while maintaining my peace.

My only wish is that the smaller complications could show how many minutes were left, instead of simply showing "0H" (less than an hour)

Thank you dev for building this app!

Great app ⭐️

This app is the app that I have been looking for on the whole app store. It allows me to view the time left to each event on my calendar. My favourite is the lock screen widget next to the date and time.
I would love it even more if there was more complications and widgets for the apple watch for example a countdown rather than a circular progress bar and the ability to customise them.
Great app definitely deserves 5 stars looking forward to new widgets.

Great app that fills a need!

This is a great believe there’s nothing out there really like it. I can’t believe it’s totally free. Thank you so much for making it!

I do have one feature request. It would be great to see at least part of the title of the next calendar appointment on the corner widgets of the watch rather than just the hourglass icon.

Great and simple. Want more!

Perfect for my needs. Took forever to find it since all other countdown apps seem to not sync w calendar or have the simple widget.

Love to use it on my Apple Watch to show time remaining until my next meeting. The iPhone widget is useful but ugly so I hid it in a Smart Stack.

Appreciate the app. Would pay for a pro version for more customizability.

Update: NOT Broken on watchOS 10!

Below is what I originally wrote, which turned out to be due to an issue with my watch staying connected to my iPhone after updating to watchOS 10 and/or updating my phone to iOS 17. I had to unpair my watch but now everything works again. Cal Countdown is an amazing, can’t-do-without app!! So glad my issue was resolved.

This app used to provide an excellent, extremely useful watch complication, but it has suddenly stopped working on the latest watchOS. Perhaps something to do with changes Apple made to granting calendar permissions? I recall seeing other apps having to ask for calendar permissions in a very new way, granular after the update to wacthOS 10 and iOS 17.
