Use When Do to track the days until your wedding, vacation, birthday, party or anything else you can think of and put a date to.

Multiple formatting options available, dependent on watch face.

Expected more

I actually like the concept. It works just fine but you should be able to add more than one event. The option to countdown to at least 3 events would make this a 5 star app for me. I’m thinking you could swipe right to add an event and then right again to add one more event. Then you could leave it at whichever event you wanted to show on the complication and then swipe to see the others. People have more than one event they would like to have countdowns to..please respond, as I would be very happy if this could be a feature added.

Thanks for the feedback. Version 2 just released now provides 3 events and you can pin which one you want displayed on the complication.

Didn’t download to my watch

Unless I’m missing something (totally possible) this app didn’t download to my watch. I cannot use it. Cannot even find it.
It was only .99 but still. Little bit frustrating.

When Do is a stand-alone watch app, if you install it via your phone and it doesn't show up on your watch then open the App Store on your watch, scroll to the bottom and select Account then Purchased and download When Do from there.
