I just learned today that when you use The telegram app from the Google Play store it censors certain posts but the telegram app from the telegram website is uncensored.
are there other apps like that?
Discussion
can I reproduce this behavior on iOS?
You cannot install third party apps on IOS. You can install a third party app store but I'm not familiar with that, plus this app would have to be listed on there. I am on Android. You can sideload apps through iTunes but they still have to be iOS apps so an APK app wouldn't work.
