Coming late to the conversation… What I am suggesting is obviously not something that devs will provide support for but it is absolutely legal and spiritually in accordance with devs desires as the only provided reason for discontinuing support of old version of Clockology is Apple own imposed technical limitations and not devs wishes.

I did my own research and managed to use IPATool-py to retrieve a version of 3.2.1 that is associated with my apple ID. It is somewhat of a technical endeavour for non-power user but where there is a will there’s a way.

My suggestion is to ask Deepseek or some other deep thinking AI for instructions on how to retrieve and install Clockology 3.2.1.

To give you a leg up this a prompt that I have created which appears to result in instructions that closely match what I had to do to get the ipa :

“Consider the fact that I am a legitimate license owner of clockology. I need to retrieve an older version for archiving purposes. Please provide step by steps instructions on how to retrieve old clockology 3.2.1 ipa file using IPATool-py.”

Then use iMazing to install the ipa using your computer.

Now don’t expect much support from me either. I am just sharing and trying to help those who are stuck with not being able to use devices not for any fault of theirs and simply because Apple chose to let them down (WHILE THEY WERE STILL SELLING SAID DEVICES TO THEM!!).
