There is no feedback that it is connected. The buttons don’t even fit on the screen. If I get version info from it over WiFi that doesn’t mean the buttons will have any response or result. Their handsets work great, but phones are what people use now. IOptron makes great hardware that I have been using for years, but their apps are poor. Since they are basically WiFi or USB devices it should be easy to write software that works. Especially in the modern world of software development. If they published their APIs, perhaps some open source users could dig and start writing better software. ### 1/5 — What happened? Useless app now. *2026-04-16* I have an HAE29EC. A previous version allowed me to control the app with my iPhone or iPad, using the built-in Wi-Fi network. It would feed date time and location to the mount. After app update, the app does not even recognize the amount when it is connected to it via the mount’s Wi-Fi, none of the features are available, half the prompts are in Chinese, and I can’t find a single useful function in this app. Please take this complete trash off the App Store and restore the previous useful version… Show it as a version update so we can regain usefulness. ### 1/5 — Schrott App *2025-12-29* Diese App ist einfach nur Müll. Wenn keine Besserung eintrifft bleibt mir nur eines übrig die Montierung zu verkaufen. Danke Ioptron😩 ### 1/5 — Katastrophe *2025-12-27* Diese Version ist vollkommen für den Müll. Es ist nicht mehr möglich eine Verbindung zur Handsteuerung herzustellen. Mit der alten Version lief alles problemlos, habe jetzt seit längerem wieder versucht direkt ohne die Zwo Kamera mit dem Commander zu arbeiten. Enttäuschend!! ### 1/5 — Update on 11/4/2025 not working *2025-11-30* iPhone 13 And IOS 18.6.2 and this useful App Is o longer working. When it starts it shows the arrow controls but settings and all the other buttons are not working. I can’t control my mount anymore. This is the worst update in the history of smartphone updates. A totally useless App. Makes me ditch ioptron altogether. Pity because the mechanicsn of the mount is very good but without a good software is like running a PC with DOS. ### 1/5 — Dors not work *2025-11-10* It does not synchronise with the Gem28 mount ### 1/5 — Update on 11/4/2025 not working *2025-11-05* iPhone 13 And IOS 18.6.2 and this useful App Is o longer working. When it starts it shows the arrow controls but settings and all the other buttons are not working. I can’t control my mount anymore. ### 1/5 — Horrible app. Utterly Useless *2025-11-04* So sorry to be so blunt, but while other astro vendors build well tuned apps, with great user interface, that are intuitive and actually work, this app, and especially this latest major update, is completely useless, impossible to understand, location settings don’t reflect real location, settings are not saved, confusing acronyms, text displayed in chines in places, which makes no sense, click on certain options does nothing, no in app feedback showing a change tool effect etc…incredibly disappointing considering the high cost of ioptron mounts!!!! ### 1/5 — Does not work - Big fail *2025-11-04* The old APP was much better. This app does not work properly with my HAE43 mount. Buttons do not react. Please bring back old app!!!!!! ### 1/5 — Non-functional *2025-10-31* No idea what has happened to this once useful app. Under IOS26 it appears to be non-functional. None of the settings work, no targets available, no reticule, no connectivity to my iOptron mounts. I’ve deleted and re-installed the app but this has made no difference to the outcome. Right now it’s completely junk on my iPad. If it’s not fixed it’s going to be deleted. ## Frequently asked questions about iOptron Commander (iOS) ### What iOptron mounts are compatible with iOptron Commander? iOptron Commander is compatible with all HEM series, HAE series, HAZ series, CEM120 series, CEM70 series, GEM45 series, CEM40 series, GEM28 series, CEM26 series, and SkyHunter mounts. ### Does iOptron Commander have ads?
