Observer Pro

iOS 8.0.2 Iphone 5 MD297B/A Not possible start, app will crash.. :(

I have a limited view from my yard so this is incredibly helpful for planning out which objects are visible and the timing. I’ve tried a bunch of apps and methods and this is by far the best solution. Very, very well done. My only tiny request would be to add a filters. Thank you for an amazing app!

This is the observing app I’ve been looking for. I am surrounded by woods, with only a few observing windows widely spaced around my property in various directions. I also have an observation site a couple blocks away on the edge of a lake. This app is perfect for comparing the different sites and deciding which is best, and how long I have on target for astrophotography. Also, the method for tracing the horizon at each site couldn’t be simpler. I only had to spend 15 minutes in freezing weather to measure the horizon at six sites around the yard. One little issue I’m seeing is that on my iPad Pro 2022 with iPadOS 17.3 is that when I edit a site name the on-screen keyboard won’t go away when the “Done” button is clicked. I have to close the app and restart it to get rid of the keyboard. One other reviewer also noted this behavior. Also, this app is for iPhone, so those of us with iPads have to deal with the clunky interface. If the keyboard bug gets fixed, and a native iPad version is released, this would be a 5-star app. One last note to those thinking about whether the app is worth $14- considering what you probably spent on your astronomy or astrophotography setup, this cost is a drop in the bucket and it will save you much time and irritation over using other apps that don’t really come close in functionality. However, the developer hasn’t updated this app in 3 years, and it has a bug, so don’t expect curb service for your $14.

Utility is wonderfully useful. I do have one bug to report. Once the iOS keyboard is up to search or type it won’t go away. Have to force close and reopen.

It shows exactly when an object comes into view and when it leaves.

I concur with what other reviewers have said here. This app is super useful for planning observing sessions. It’s especially useful for those of us who are forced to observe the sky with many obstructions around - tall trees, buildings, etc. The app allows users to build site specific obstruction profiles that then show what objects are visible at what times. Each object in the database has a graph showing if it’s visible and what times it will be visible along with other observing data. Can’t recommend this app more especially if you view from an obstructed site. I only wish the developer would make an iPad version of the app. Clear skies!

Great for planning. Just wish it included planets, comets, and asteroids

Sorry this app not for me I want to delete it is there any way to get my money back??? Thank you

Excellent app for knowing when your target will be visible and the best viewing times.

Very useful in helping prioritize targets for areas with obstructions. Have not figured out how to prioritize targets where I am doing narrow band imaging and don’t care so much if the moon is up. Can sort on just nebula I guess but it still ranks items based amount of time they are up when the moon is not.
