How to tell if certain pre-2015 app is 64 bit? As there are quite some rumors, about iOS 11 dropping support for 32 bit apps, I need to know, how to tell if an app is 64-bit. I know, that if it was published after february 2015, or if it was updated after june 2015, it has to have 64-bit support. But the app in question - IPELA Communication Mobile by Sony Corporation - was last updated on June 10th 2015. How can i be absolutely sure, that - just in case the rumors come true - I can still use it?
The easy way for me is to install the app on iOS 10.3 (or later) device. 

Then open the settings app.


tap general
tap About
tap Applications


iOS will report on the possibility to update all 32 bit apps you have installed on the device by letting you tap to each entry in the App Store where the developer web site is another tap away.
