Mostly great app and love the new widget, but...

Update: “system” theme fixed in widget so it automatically switches between light and dark. One star added.

I’ve used this app for years, mostly to check the sunrise and sunset times, and the moon phase. I love the new widget. My one nit is the color scheme. I have iOS set to automatically shift from light during the day to dark at night. It would be really nice if LunaSolCal also supported this. In the main app, the only choices are dark and light. The widget offers dark, light, and system. I hoped that “system” meant that it would select whatever scheme iOS was using. But as far as I can tell, system doesn’t do anything. Still, other than that it’s a great app.

Developer,
Thank you for the reply.

Since leaving my updated review about this problem I have discovered that sometimes opening and closing the app is enough the restore notifications. However when that fails, turning off the alarm in question, turning it back on, re-selecting both the time and the tone restores notification mode.

I do not use “do not disturb” mode, so that isn’t the problem here. My other apps consistently send notifications so I don’t think it’s a problem with the settings or iPhone. It seems that when I mute a notification while the alarm is going off the app turns off future notifications. I haven’t tested this, it may only be an annoying coincidence. I gave back 2 stars because of your quick reply And I figured out how to fix it.

Alarms for sunrise and sunset no longer work. I have turned them off and back on, adjusted them (to go off one minute before the event, etc.) and changed the alarm sound; nothing works. Alarms still go off for moon rise and moon set, solar noon, and the equinoxes so I don’t think it is my iPhone being squirrelly.
Unfortunately, the sunrise and sunset alarms are most important alarms. Not having them is a huge disappointment.

This is a fantastic app — as it always has been — it works very well with the latest iPhone OS. I especially like the customizable alarms which you can set for any number of celestial events.
Keep up the good work guys!

Developer Response ,

One reason why certain alarms won't work might be that the (scheduled) "Do not disturb" mode has been turned on on your iPhone.

My favorite!

I check this app multiple times a day. I am always checking where the sun and moon are in the sky. I love the well thought out graphics. It is easy to use and a great aid for explaining the solar and lunar dynamics to others. There are no substitute apps for this one. It is one of a kind!
