App cannot run on jail broken device

There are a few signs you can look for to determine if your iPhone is jailbroken:

1. Look for apps that wouldn't typically be available on the App Store. Some jailbreak apps may have unique icons or names that stand out.
2. Jailbreaking can sometimes cause instability or unusual behavior in the operating system. If you're experiencing frequent crashes, freezes, or strange errors, it could be a sign of a jailbroken device.
3. Jailbreaking can potentially compromise the security of your device, making it more susceptible to malware or unauthorized access. If you notice any unusual activities, such as unauthorized logins or data breaches, it might indicate a jailbroken device.
4. If you have technical knowledge, you can use apps or tools to access system files and check for alterations or files associated with jailbreaking.

Remember that the absence of Cydia doesn't necessarily mean your phone isn't jailbroken. Some advanced users can hide Cydia or use alternative methods to install unauthorized apps without Cydia appearing on the home screen. If you're unsure or suspect that your device might be compromised, you might consider restoring your iPhone to its factory settings to remove any jailbreak and ensure it's secure. However, note that this will erase all data on your phone, so make sure to back up important information before doing so.

Where did you download the app from?

Well, if you have not jailbroken your phone, your only option is to contact the developers and support folks for the app to ask them how to run the app on your phone........in other words, what settings on the iPhone are required for their app?

So you downloaded an app from the App Store (thanks Katana-San) and it tells you that? You just contact the developers and ask them what's all about that interesting app

Hello~ It’s in the App Store.
