Traccar Client for IPhone 5S with OS 12.5.7
You would probably have to compile it yourself and install directly on the device using Xcode.
Ok I'll try
There are websites where you can download older versions of app apk's. Websites like apkpure (google it). I am not saying its recommended but old apk versions can be found.
Track-trace you're talking about Android. On iOS it's not possible to sideload an app, unless you jailbreak the OS, which is even more complicated.
Ah yes Anton, you are right (as always :)
I want to install Traccar client for IPhone 5S with OS 12.5.7, I don't know how to do this. As far as I understand, there are older versions on Github, but how is the installation of an older app carried out from there?
