@DoomMeister knows more about which Mantis models, which App versions work with which smartphones/tablets. But here are some links to at least some files.
'Mantis Files"
It appears that all Yuneec apps are missing on the US App Store for iOS users. Hopefully it will be restored soon. This has happened once a year for several years now. I don’t understand why Apple can’t leave apps alone.
@Enrico Jorysch are the apps (Yuneec Pilot, CGO, CGO4, and Breeze Cam) still available on the EU Apple App Stores? Can you find out from your Yuneec contacts why these are dropped from the App Store every year?
If you are using an Android device the link in post #2 has some versions of the app, or you can find the Yuneec Pilot app on most apk sites like APKPure.
Google removed them all from the Play store for Android too... I went looking for the various camera control apps for the CGO3 AND 4 and such the other day and they're gone.
My understanding is it's because none of them have been updated in recent years, and target very old versions of Android/iOS, which Google and Apple consider to be insecure and outdated... Fine logic, except if the app is for a hardware product, it's not like you can just switch to a different software that's more modern.
The Android versions have been out of the Play Store for several years, but with Android you can find the apk files in other places. Unfortunately that is not the case for iOS users.
I have installed all of Yuneec's iOS apps on my iPhone 15 Pro Max.
Is there a way to back up these apps so that I can share them with others?
I haven't found a way to do this yet.
You can supposedly use the iTunes app on your PC to make a full backup of your phone and recover the app for yourself, but no way to share it with others to my knowledge Enrico.
I have Yuneec Pilot, Breeze Cam, CGO, and CGO4 backed up this way on my iPhone X and XS.
I contacted Apple Support and they are utterly useless. They are nothing more than script reading monkeys and say to contact the developer even if Apple is the one removing the app. It has to be Apple for the apps to disappear every year since 2019.
