So you fork out £630 for the drone, and Parrot are still trying to squeeze more money out of you by making you pay for app features. Nice.
The Anafi is Parrot's answer to the DJI Mavic Pro. It's £630 price tag is closer to the £700 Mavic Air, but the spec is comparable to the £800 Mavic Pro's . What you don't get with the Anafi is the software, as they've made features the Mavic's include, as software DLC for their drone (you have to make money somewhere!). If you're thinking of getting a drone and the Anafi is more your budget, then getting the software for under £1 is a bargain as it's normally £17.99. There's a nice Mavic Air vs Anafi video here that will give you a taste:
