I'm trying to find out which cipher suites and SSL/TLS protocol an app uses. In the privacy policy it is written that it uses SSLv3 but when I tested the server of the app's developer using an SSL checker it said it supports TLS 1.2 1.1 1.0 and SSL 3.0. Is there any way to determine the cipher suites used and the exact protocol an app uses to send data to a server?

You could install a web proxy on your router or a computer and there are even web proxies on iOS like Charles Proxy.
There are great tutorials on the site above using the Mac / Linux / Windows version of this to debug and investigate ios / iPhone traffic. The iOS app to run this on the device itself is here: Charles Proxy by XK72
