iOS 15 and iPadOS 15 Beta 7 is Now Available to Download Without a Developer Account with Apple

Apple seeded the seventh beta of iOS 15 and iPadOS 15 to registered developers with an iPhone and iPad just yesterday. But, if you are a non-developer and want to try out the newly released software, then you can go right ahead and install it.

All you have to do is sign up for Apple's Beta Software Program and install iOS 15 or iPadOS 15 onto your device. For full steps, check out the following:

Alternatively, you can find the official iOS configuration profile for your iPhone and iPad in order to download the beta. Once installed, everything will be delivered to you over the air. But, we will not endorse this method at this point as the public beta is safer to try out and is more mature enough for everyone to try out safely.
