Love it but...

I love this app. But I have to give 4 stars because you have not keep up your app! Last time your app was updated was over a year ago!! Please update your app to keep customers happy.

One thing I want from a program like this is to be able to dump the fake horizon that the programmers thoughtfully (ha!) provide and substitute it with something less obnoxious. (As if I want to see the “horizon" of NewYork City every friggin’ time I open it.) But guess what — THERE IS NO EASY WAY TO DO THAT as far as I can tell. I set the preferences to include a different horizon, close the app and reopen it, and there’s friggin’ NYC again!!! I tried saving a file and setting the app to open using that file, but that didn’t work either.

This program fails the simplest test of usability. WORSE - there are no menus. All the controls are hidden in cutsey little icons. Wasted money!

Developer Response ,

Dear John-MD, you can easily set the app to open using a customized preferences file: Please go to Configure > Preferences > Startup Sky submenu. Select the 'Last session' option from there (instead of the 'Default' option). Now all settings from your previous Redshift session should be applied upon the next launch of the app. If you need some more help with resolving the issues you mentioned, please contact our support team via

Superb Program

Over many years, I've had many programs that model the cosmos…

Redshift Premium is by far the Best 😊
