Used to work for a company bug testing their app. We used a service called installr which worked on both devices. On iOS you installed a certificate/profile and on android, it downloaded an apk which then got installed manually. 100% of the time it was easier and quicker on iOS. And this was downloaded from the internet, not a mac.
Android has been losing openness, iOS has been gaining it, they've finally met in the middle with the Android 7 release.
