Erasing apps from iCloud involves removing them from your iCloud account, making them inaccessible across all your devices. This can be useful for decluttering your device’s storage, removing unused apps, or resolving app-related issues.
While deleting apps from your device only removes them locally, erasing them from iCloud ensures they are removed from your account entirely. This prevents them from reappearing on your devices if you restore from an iCloud backup.
