Same thing, it seems it would be simpler for me than using WorldNomads. I don't really know where I'll be next more than a 2-3 weeks ahead, and every time I finalize my next couple legs and head somewhere new, I need to apply for a new policy with WorldNomads. Also WorldNomads can be pretty expensive, sometimes it's a bit of a turn off. But I sort of trust that they'll cover me since they cater to "extreme" activities, so I still go with them.
Wondering what sort of coverage SafetyWing will do and their policy is way too long and opaque for me to make sense of. If they could have something that's like "You can go canyoneering/scuba diving/mountain biking" like WorldNomads does, and add to this "anywhere in the world with a subscription and we'll cover you for x$/month", I'd be sold. Even if it's the same price as WorldNomads in the end, just for the convenience.
