This is a really nice app overall, but setting reminders seems really difficult and awkward. I was looking for a way to set moon phase reminders, but can't see way to do this. I click on the reminders section and it tells me I need to tap the bell icon. I do that on the same page, it does nothing. I also look elsewhere in the app and it's not always there. All this needs is a list of upcoming events with a search feature for them, with the icon that you can just set a quick reminder on.

Wow! Installed, tried, bought the Premium within 20 minutes! This app has exactly what I want; the ability to show objects visible to the naked eye for clarity (which can be changed quickly when I get the binoculars and/or telescope out) and up-to-date events and information. After using a few alternatives over the years, this is now the only one installed locally for me. Easy to use, logical interface, plenty of features, looks great !

You can literally zoom in all all the planets, the sun is animated (you can't zoom into the stars but I think that's a lot to ask for to zoom into every single star) it's an awesome app last night I actually saw Cassiopeia!!! it's extremely accurate, it also includes nebulas which are gorgeous. I love zooming into the planets, the quality is amazing 😭
