Ratings and reviews

I decided try this app after taking an astronomy course for college and gazing at the Pixel Live Wallpapers - earth display. The app provides legit data and enough user options to customize it for a wide user scope. One thing i would like is for the viewport to adjust when utilizing a non-native dpi and the option to separately set opacity for the rising and twilight widgets (the smaller ones : 1x1), or if you set update parameter 'customily'. Good job on the app, it works and looks good!

1/9/2023 update: I sent the dev a note about moonset times mismatching & we worked thru a fix via emails. WOW! Pleiades ★⁷ Award unlocked!!! [OP] TOO MUCH INFORMATION! ...And that's a good thing! I've turned on so many details that when I launch the app it takes me ten minutes to remember what each datum means. Could you add the option to reorder the blocks so we can put our favorites at the top? This app gets the "Corona Borealis Prize" - 6 bright stars!

A phenomenal volume of astronomical ephemeris in one place, presented in a compact layout. Saves hunting around using different sources. Update: Nov 2025, this app goes from strength to strength; if you've not already done so, try changing the calendar from hours to days, and then drag the bar to see how various astronomical bodies behave over time. The developer is very attentive to users.
