Not an internet access issue—seemingly at random it removes all upcoming passes from the main page. Usually this issue resolves itself after a day or two. ### 3/5 — Absturz unter ios 18 *2024-09-19* seit Update auf ios 18 stürzt die App beim Aufruf einer Sichtung sofort ab ansonsten war das immer eine super App ### 4/5 — IOS 18.0 issue *2024-09-19, version 2.9.2* I hope there is an update coming, after installing IOS 18.0 the app shuts down if you open the Details window. ### 4/5 — Crashes On iOS18 *2024-09-18, version 2.9.2* I have enjoyed this app for many years. Unfortunately after updating to iOS 18 yesterday it crashes every time I choose a sighting time. Hopefully it gets an update soon so I can continue to enjoy it. ### 4/5 — ISS Detector crashes unexpectedly. *2024-09-17, version 2.9.2* Hey Derk, good morning! I updated my iPhone 13 to iOS 18 yesterday. ISS Detector opens just fine to the main screen, and I can access the settings menu and buy packs, but whenever I tap on one of the satellites on the main screen, it opens and then the app immediately crashes. I've tried restarting my iPhone and even uninstalling and reinstalling ISS Detector, but the same issue keeps happening. Unfortunately, I can't use the app after updating to iOS 18. Thanks for your help! Cheers! ### 3/5 — App Crashing *2024-09-16, version 2.9.2* Until I updated to iPadOs18 today the app has been really good. Now the app crashes after about a second 😕 ### 5/5 — ISS Detector *2024-09-16* Défaut de Map lorsque je veux voir ou se trouve; je sélectionne ISS a un moment donné et en cliquant dessus le map s’ouvre et se ferme en 2 secondes… très bonne application que j’utilise régulièrement….. ### 4/5 — Now Working *2024-08-07, version 2.9.2* Apologies to the developer, I couldn’t get this to work last week, but then discovered a setting for ISS which allows you to toggle between ‘Visible Passes and All Passes’. Now I have this selected I can see the ISS Radar page etc, and found it very useful for doing Amateur Radio via the ISS. Plan to purchase the extension now for all the Amateur Radio Satellites. Thank you. ### 5/5 — Helped me spot the ISS 3/3 times. *2024-07-16, version 2.9.2* Hands down the go-to ISS spotting app. I can't speak for the rest of the features because I haven't tried them, but I tried to spot the ISS during 3 different scheduled sighting windows across 2 separate days. One in 2022, two in 2024 and I successfully spotted the ISS during all 3 windows. 10/10 from me. ### 3/5 — Frustrating *2024-07-15, version 2.9.2* As well as this app works, I constantly have to uninstall/reinstall or it doesn’t work at all. ## Most critical reviews (10 lowest-rated) ### 1/5 — New update unuseful *2026-04-15* The newer update makes the app unuseful for Hamradio. Just a trash! Unable to find correct altitude when the antena has any angle (left/right), and just change the view when it is close to 90°. Now I paid for a trash app, that was 100% useful before this update. **Developer response:** I'm sorry you don't like the update. There is an option in the Settings called 'Auto Stardome switch'. Turn this off to stop switching to the star dome. ### 1/5 — Not Working With My iOS 26.2.1 *2026-02-13, version 2.11.0* I’ve purchased the Amateur Radio Satellites extension. My app gets completely wiped, no satellites, won’t restore satellites even when I do a “Restore Purchased Extensions”. If I delete the app and re-download from the App Store everything is there again, but the next day the app is wiped clean again. Can’t find a customer support link. Using an Apple iPhone 15 with iOS 26.2.1. ### 1/5 — Quite literally useless *2025-04-22, version 2.9.4* I have the location set to my city, yet the times listed are just dead wrong. I've given it days to update yet it's still the same. It's about to pass overhead and it says the next sighting is in 16 hours.. ### 1/5 — Privacy settings menu doesn’t work *2024-08-13, version 2.9.2* Quickest way to get a one star review from me is to be shady about privacy. ### 1/5 — Stopped working *2024-08-07, version 2.9.2* Looked real good , bought it and the options. Worked about a week, now will not load contracted the developer. Told me reset my phone. Worked for short time. DO NOT BUY NOT WORTH THE MONEY!!! ### 1/5 — Stupid crashing *2024-07-25, version 2.9.2* I paid money for the amateur satellites and the stupid app wont work, its just showing me blank, thanks a lot! ### 1/5 — Want to Like But No Ability to Customize TLEs *2023-08-14* I paid for the add on so I could use the app to track ham satellites. It does a good job except the TLEs are far from complete. Other apps let you specify custom TLE URLs but not this one. Very disappointing. Seems like a cash grab to get people to pay for a premium license. But if you already paid for the premium license, you should be able to specify your own. You already have our money. ### 1/5 — The ISS APP vs NASA Live *2023-08-04, version 2.7.1* The is a discrepancy on your APP versus the Live reports from NASA! The Latitude and Longitude are way off when you see your APP versus NASA Live! ### 1/5 — App looks good, but invasive privacy practices! *2023-07-16, version 2.7.1* Would love to support the developer and the app, but not at the expense of being tracked and my personal information being given put. As the App Privacy explains “data may be used … to track you across apps and websites owned by other companies”!! No thank you! ### 1/5 — Keine Übertragung mehr *2023-06-05* meine App funktioniert nicht mehr, keine Übertragung seit Wochen. **Developer response:** Starte das handy ein mahl neu. Vielleicht hilft es die Standort einzustellen in die Einstellungen. ## Most praised reviews (10 highest-rated) ### 5/5 — Parabéns *2026-09-01* Estou impressionado com a precisão desse app, mostra perfeitamente a rota dos satélites. ### 5/5 — Does what it says. *2026-04-13* Exactly. Most user friendly. ### 5/5 — App todo em inglês *2026-01-06* O aplicativo é todo em inglês. Não existe opção para português no iPhone. Para Android sim. A que diz respeito à funcionalidade se propõe, é excelente. ### 5/5 — The best for amateur radio satellites *2026-01-04* This is a great app for anyone wanting to track satellites and the ISS, but it’s especially great for amateur radio. It’s possible to filter the list down to the sats you want to track, and then when a pass is happening you can track it in AR while having the frequency (with Doppler shift calculation!) on a single screen. It’s full featured and very easy to use, plus very affordable with no subscription. ### 5/5 — Intuitive *2025-10-17, version 2.10.1* Cool intuitive app ☝️😎 ### 5/5 — Please re-add feature *2025-09-14* Love the app, it’s fantastic in all ways. One caveat, previously when you clicked on a “sighting” and entered the “radar” mode, if you pressed and held, labels for everything currently in the sky would appear. This stopped happening at some point over the last 2 years. Don’t know exactly when but would love for this feature to be re added. It greatly reduced how much I used this application and the ease of information it provided. None the less, 5 stars great app. ### 5/5 — Beste App ever....😊 😊 😊 *2025-03-19* Die App macht genau das was sie soll und darüber hinaus noch viel viel mehr.😊 Bin schwer begeistert 😅 ### 5/5 — Stopped loading sats after last iPhone update *2024-11-06, version 2.9.3* Great app but why does it keep forgetting all my satellites causing me to have to reinstall? ### 5/5 — Super *2024-09-19* Nach den Update jetzt mit iOS18 einwandfrei. Bin sehr zufrieden. Eine tolle Hilfe für die Nutzung von Amateurfunksatelliten. ### 5/5 — ISS détecter *2024-09-18* Excellente application très claire et détaillée interface conviviale Merci --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
