Sort of like an HP gauge until retirement. ### 5/5 — Nice little complication *2022-11-03, version 3.4* Love this, it works as described. I had an issue wrote the programmer, and he replied and helped me. Great service. Again nice little complication for the watch! ### 4/5 — Fun app *2020-10-16, version 2.1* I’m enjoying having the app as a complication on my watch. Could you update with more types of complications? There are currently only a few compilations options Thanks ### 1/5 — Not working! *2020-07-03, version 2.0* I am still stuck with the New Years countdown the app came with. Renamed one and tried to change the date but the app closes every time I click on any of the dates. ### 3/5 — Expected more *2020-05-31* 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. **Developer response:** Thanks for the feedback. Version 2 just released now provides 3 events and you can pin which one you want displayed on the complication. ### 1/5 — Only 1 event can be put *2020-03-22, version 1.6* Could the producers add a feature that allows you to put more than 1 event? ### 1/5 — Didn’t download to my watch *2020-01-31* 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. **Developer response:** 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. ## Frequently asked questions about When Do ### What is When Do?
