One of the main things about iOS is their security. That is because Apple’s signature App Store has strict policies and that is why it takes a while to make an application online. If you create app like Google assistant, then chances are that within 3-6 weeks, your application will be approved. However on android, that time-frame is much less. That is not to say that their security is not as good, but because their measures and scales are easier compared to Apple’s. However, android has a better marketplace and that is why many choose it over iOS. What do you think?
