This works very well. It works so well thatI had it running on my iPad Mini 2 and forgot about it. after not using my the iPad for about six months, I got it out and turned it on and wondered why on one app, it was hardly showing any users and there were hardly any new posts day after day. I had it set to show me in a very small mountain town in Colorado.
I use several iPhones logged into the same iCloud account but with iCloud Drive off so that phone calls and texts stay separate on each phone and normally that's not a problem. When I used the location faker tweak, it messed with certain things between the phons such as my weather cities in the weather app. Normally when I add a city on one phone, it automatically gets added to the other iPhones. With location faker active, the weather cities would not get added to the other phones.
Just be careful how you use it because some apps can break or not work correctly.
