• Measure your local horizon profile in minutes with your iPhone.
• Unique charts completely take the guesswork out of predicting object visibility. Your house, trees, mountains, or any other obstructions are completely factored in to all visibility charts.
• New to astronomy? The Featured object list shows a list of objects specific to your location and local horizon that are great for observing right now.
• Keep a list of your favorite observing sites, each with their own local horizon profile. Compare object visibility between sites to find the best spot to setup your scope.
• There's a lot to observe! Observer Pro gives you a place to maintain a list of your favorite objects as well as an observing list that you can take with you to the eyepiece.

Observer Pro FAQ
Is Observer Pro free?
Yes, Observer Pro is completely free and it doesn't have any in-app purchases or subscriptions.
Is Observer Pro legit?
✅ The Observer Pro app appears to be high-quality and legitimate. Users are very satisfied.
Eine sehr schöne und gut durchdachte App. Die Funktion einen eigenen Horizont hinzuzufügen ist prima. Leider wird die App seit 4 Jahren nicht mehr weiterentwickelt. Hin und wieder stürzt sie bei mir ab. Trotzdem gebe ich alle Sterne da sie konkurrenzlos ist und in den allermeisten Fällen ihre Aufgabe erfüllt.
Not all work
weather feature dont work
horizon feature dont work
ugly old style
really expensive, hope for a biiiigggg update soon.
only 3stars
Optimaler Beobachtungsplaner
Die Berücksichtigung des individuellen Horizonts am Standort ist das Beste! Endlich kann ich (wieder) auf einen Blick sehen, was sich in dieser Nacht beobachten lässt.
Danke für die Weiterentwicklung!
Lohnt sich sehr
Das Planen einer Beobachtungsnacht ist komfortabel und schnell gemacht. Klasse, dass ich nun einfach den Horizont meiner Gartensternwarte mit berücksichtigen kann.
Da ich 1-2 mal im Jahr auch im südlichen Afrika beobachte, fehlen mir zur besseren Orientierung auf der Sky Map die Sterne südlich von DEC -30 Grad. Auch wenn hier ein paar Sterne fehlen: hier lasse ich alle fünf stehen.
Tolles Programm
Wenn noch GPS mit Objektfindung dann ist das Programm fünf Sterne Wert. Empfehlung!!!
Excellent app to plan DSOs
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!
Awesome observing app, easy to set horizons
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.
Fantastic but not perfect
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.
Love horizon measurement tool.
It shows exactly when an object comes into view and when it leaves.
Outstanding astronomical observing app
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!
