is it possible to use bug hunter without having an iphone

Answer 1

Not from the website. It only works in the apps. There are apps for iOS and Android. You can setup an Android emulator in Windows and you could setup an iOS emulator in MacOS. These present their own challenges. Probably more trouble than it's worth.

It's really easiest is you have an iPhone, iPad, or Android phone or tablet. If not, then you need an emulator.
