The reason Retro Bowl is running in slow motion on iOS is likely related to issues with iOS 26. Users have reported that after upgrading to iOS 26, Retro Bowl (and some related games) experience slowing or lagging gameplay. The game developers have acknowledged the problem and noted that it may be triggered by notifications or quick app switching, which leads to performance challenges. They suggest closing other apps while playing as a temporary workaround until Apple addresses the issue in a software update.
Additional causes of Retro Bowl running slow on a device can include too many background apps running, full device storage, or outdated app versions. Restarting the device or updating the app may help improve performance, but for iOS 26 specifically, the problem seems to be a known bug linked to that OS version.
In summary, the slow motion in Retro Bowl on iOS is mostly tied to bugs in iOS 26 impacting game performance, particularly when receiving notifications or switching apps, with the developers monitoring the situation and waiting for an Apple fix.
