iOS 10 vs. iOS 9 Speed Test

One of the biggest updates on iOS 10 is Siri, which has been made even smarter and it's now open to developers. That means you'll start seeing the personal assistant pop up in third party apps too.
On iOS 9, Apple introduced Siri Suggestions which displayed contacts and apps it predicted would be most useful to you at a particular time and location. It also offered up smarter answers to requests – but not on the same scale as the iOS 10 update.
Because Siri is now open to third party apps, you'll be able to say things like "Send a WeChat to Nancy saying I'll be 5 minutes late", and it'll do just that. Siri is also now smart enough to understand that command in a variety of ways, which means you don't have to say phrases in a set order for it to work.
That's what Apple claims anyway – we'll remain on the fence until we actually get a hold of it.
