Cool muster just works. I purchased other products that didn’t work and was difficult to setup and use. I wanted to backup four years of iOS messages. Coolmuster did this like a breeze. I wasn’t required to several pages of information. One of the best products I purchased in 2020. I have been working with computers since 1982.

It enables some download of text threads which is what I bought it for but it will not download the entire content nor will the fix suggested work to alleviate this issue. There does not seem to be a solution for this issue except to give the purchase price back.
It does download most of text threads but not all. Specifically it only got one side of a two sided conversation or it only partially got got both sides of a text thread. So it depends on what you want the program for if it will work for you

Sometimes it can be a bit troublesome to establish connection - in my case between an Android phone and an iMac; but once the systems are connected it works just fine! :)

I use this app regularly for Android to keep copies of my text messages on my computer for work purposes. I like the option to export by date. I find the iOS version to be more cumbersome as it doesn't include the associated with the number.

Unfortunately Backup process stops at 2/3 completion...
Unfortunately I have tried several times to backup all the data from my oneplus 6; more than 100 GB of photo’s and video’s. This was never successfull. After 2/3rd the process stopped. Contact with the helpdesk did not result in a 100% complete backup. It looked so promissing...
