New Cardio app for TrollStore lets users customize Apple Pay card images without a jailbreak

Another developer appears to be taking advantage of TrollStore for iOS & iPadOS 14.0-15.4.1 beta 4 devices to tinker with parameters of these operating systems that wouldn’t ordinarily be customizable without a jailbreak. The latest attempt comes by way of a new app called Cardio by cisc0disco.

Cardio TrollStore app customizes Apple Pay card images

Cardio has nothing to do with your heart health, but instead has everything to do with your Apple Pay cards. This app lets the end user change the images that are displayed for Apple Pay credit and debit cards, effectively mimicking one of the primary features of a popular jailbreak tweak called Sydney that we showed you back in May.

Cardio certainly doesn’t offer as many options as Sydney, but given how it can be installed and used on non-jailbroken iOS 15.0-15.1.1 devices by way of TrollStore, we’d say it’s pretty darn impressive.

When you open the Cardio app, you can view any of your available Apple Pay cards and tap on them to customize them. By swiping, you can move between different cards, and by tapping on them, you can pick a different image to use as the card’s background.

There’s not much else to be said here since Cardio is a particularly simple app, but if you like the idea of setting custom card backgrounds without having to do it manually through Filza, then this is a great way to streamline the process.

It’s worth noting that some users on various device types and firmware versions have taken to /r/jailbreak to report crashing in the initial v1.0 release, but it doesn’t appear to be affecting everyone and we expect that this crash will be resolved in a future update.

Those interested in learning more about or trying Cardio can head over to the developer’s GitHub page.
